APPLICATION NOTES GENERAL: Endot Endopoly and Golden Jet Pipe are flexible, black, coiled pipes and EndoPure is a blue pipe with a clear core, all of which are produced from polyethylene resins with the classification of PE 4710/PE 3408 or PE 3406. The primary difference in the resins is the wall thickness required to achieve a specific pressure rating. PE 4710/PE 3408 having the thinnest wall and PE 3406 having a slightly heavier wall for equivalent rating. The type of resin has little to do with the installation method. (See Size Comparison Chart for details on product dimensions) Endot Industries produces polyethylene pipe using PE 4710/PE 3408 and PE 3406 resins. Endot pipe is available in pressure o ratings of 100 PSI through 200 PSI. All pressure ratings are for pipe and tubing at 73.4 F. (See Temperature vs. Pressure Rating Chart) Endot produces three types of polyethylene water pipe, ID controlled pipe, manufactured to ASTM specification D2239, commonly called IPS (Iron Pipe Size) pipe, OD controlled IPS pipe manufactured to ASTM D3035 and ASTM D2447, and OD controlled tubing manufactured to ASTM specification D2737, known as CTS (Copper Tube Size) or as WST (Water Service Tubing). ASTM (American Society for Testing and Materials) is a widely recognized organization that develops standards on characteristics and performance of materials, products, systems and services. Endot brand name products EndoPure, Endopoly, Golden Jet, Super Golden Jet, Black Diamond, Super and Poly-Xtra are National Sanitation Foundation (NSF) Certified for use with potable drinking water. NSF Certification provides the user with the highest level of confidence the pipe will not interact with nor release any chemicals into the water supply. NSF Certified pipe and tubing is recognized by the permanent imprint of the NSF logo on the pipe. The NSF Certification also assures the user the pipe is produced from one of the highest grades of raw material available. All Endot pipe and tubing is permanently marked with indent printing. Color coded printing identifies various pressure rating and grades. STORAGE AND HANDLING: Endot pipe should be stored so as to prevent damage by crushing or piercing. Coils of black pipe may be stored outdoors without damage from weather or Ultraviolet exposure. Colored pipe contains Ultraviolet inhibitors to protect it from sunlight, but colored pipe should be stored in a protected area away from Ultraviolet exposure. Do not expose pipe and tubing to excessive heat. Do not drag across rough ground and avoid hitting or placement on sharp objects when storing or placing in service. Before pipe or tubing is installed each length should be inspected for transport damage, cuts, punctures or excessive abrasion. Damage from shipping or handling may have occurred. Although each coil is clean and sealed or capped when it leaves the factory dirt or debris may have entered the pipe during installation. Flushing the pipe before final connections are made is good practice. APPLICATION NOTES SIZES - PRESSURE RATINGS - COIL SIZES SIZE RANGE: Iron Pipe Size (IPS) Copper Tube Size (CTS or WST) OD Controlled ASTM D3035 & D2447 1/2" through 3" 3/4" through 2" 3/4” through 3” STANDARD INSIDE DIAMETER RATIO (SDR or SIDR): Each size of IPS pipe (ASTM D2239) in each pressure range is rated with a SIDR number (Standard Inside Diameter Ratio). The SIDR is determined by dividing the Nominal ID by the Minimum Wall Thickness. STANDARD OUTSIDE DIAMETER RATIO (SDR or SODR): OD controlled tubing (ASTM D2737, & D3035) is rated by Standard Outside Dimension Ratio (SODR) which is determined by dividing the Nominal OD by the Minimum Wall Thickness. When selecting external compression fittings for use on IPS or CTS products the SIDR or SODR must be considered. Selecting external compression fittings by pressure rating could result in the selection of the wrong fitting. (See Size Comparison Chart) Table # 1, Size Comparison Chart, lists the SIDR and SODR for each of the sizes and pressure ratings manufactured by Endot Industries. See ASTM specifications D2737 and D2239 for details on IPS and CTS specifications. PRESSURE RATINGS: IPS pipe, ASTM D2239, is produced from 80 PSI to 200 PSI. CTS tubing, ASTM D2737, is produced in 160 PSI with PE 3406 resin and 200 PSI with PE 4710/PE 3408 resin. COIL SIZES: The standard lengths of pipe coils range from 100 feet through 500 feet with each manufacturer having specific stock coil sizes for each size and pressure rating. Endot's standard coil sizes may be found on the List Price Sheet for each product type. Coils of 1000 feet and longer can be produced to order. Endot Industries stocks large cable reels to allow the production of very long lengths of the heavier pipe such as 160 PSI and 200 PSI where 1000 ft. coils may weigh up to 950 lbs. The use of a reel allows easier handling of these heavy pipes yet eliminates the need for joints in long sections of pipe. Lengths of over 6000 feet may be packaged on reels. Smaller coils can also be custom produced. APPLICATION NOTES PRESSURE RATING VS. TEMPERATURE OF ENDOT PIPE AND TUBING All pressure ratings of Endot polyethylene pipe and tubing are for an operating temperature of 73.4oF. Endot pipe can be used at temperatures higher than the rated 73.4oF, but the user must consider the reduced pressure capacity of the pipe. Every 10oF. rise or fall in temperature from 73.4oF will reduce or increase the pressure rating of the pipe by approximately 12%.

APPLICATION NOTES INSTALLATION METHODS JOINING IPS PIPE: Two generally accepted methods of mechanically connecting sections of IPS (ASTM D2239) and CTS (ASTM D2737) polyethylene water pipe and tubing together or joining it to other piping materials are available. For IPS the most common method is insert fittings made from brass or PVC that seals using gear clamps. IPS pipe and CTS tubing can be joined using external compression fittings that seal via internal gaskets and external clamping. Insert fittings cannot be used on polyethylene water tubing (CTS) made to ASTM D2737. The Size Comparison Chart lists the various sizes of IPS pipe made by Endot and the nominal dimensions of those sizes. ASTM D2609 outlines the dimensional requirements for plastic insert fittings. INSERT FITTINGS: Use insert fittings with sufficient length to allow the application of two clamps on each side. Use clamps produced from all stainless steel including the screw. Place clamp screws 180o opposite each other. Be sure clamps are over the barb of the fitting and not the flat. Do not use any lubricants, sealing compounds or pipe dope. Use of these materials voids all warranties and may cause damage to the pipe. Heavy walled, large diameter pipe, 160 PSI and 200 PSI and 1-1/4" and larger, require the use of brass or galvanized insert fittings and industrial type clamping devices. For 1-1/2" and 2" ID 200 PSI pipe external compression fittings specifically designed for use with IPS pipe are strongly recommended. External compression fittings provide an effective, reliable coupling for heavy wall, large diameter pipe. In cold weather it may be necessary to warm the pipe in order to insert the fitting. DO NOT USE A TORCH TO HEAT THE PIPE. Gently warm the pipe using hot water or by storing the pipe in a warm place prior to use. EXTERNAL COMPRESSION FITTINGS: External compression fittings can be used on both CTS and IPS products. Since IPS pipe is Inside Diameter controlled the external type fitting has to have sufficient tolerance to accommodate the normal and acceptable ASTM specified variations in OD. Ease of insertion of the pipe into the fitting will vary with the normal tolerance variation of the fittings and the pipe. It is important to specify the SIDR (or SODR) of the pipe in use when ordering external fittings. See The Size Comparison Chart for SIDR information and for the comparison of sizes between the various resin types. When assembling a joint using one of these fittings follow the manufacturer's directions carefully. If the fitting manufacturer calls for insert stiffeners they must be used to insure a leak free joint. DO NOT LUBRICATE THE PIPE Lubrication other than water should not be used. Use of any lubricants, sealing compounds or pipe dope voids all warranties for Endot pipe and tubing and may cause damage to the pipe or tubing. APPLICATION NOTES HEAT FUSION OF ENDOT PE 4710/PE 3408 PIPE & TUBING INSTALLING PIPE AND TUBING USING FUSION WELDING: Endot products may be joined by Thermal Heat Fusion. Follow the tooling manufacturer guidelines carefully when joining pipe or tubing with thermal fusion. Thermal fusion joints when properly made are as strong or stronger than the pipe itself and eliminate any flow restrictions.

Shortened heating times can result in an incomplete bond of materials and a weak joint that may fail. Endot Industries, Inc. does not recommend fusion of Endot pipe and tubing to materials of a different grade or specification or to material classified as “wide spec”. Fusion joints between dissimilar materials may fail even when the time and temperature settings are correct. Polyethylene pipe is chemically inert and there are no known glues that can be used to create effective joints that will stand up over long periods of time. APPLICATION NOTES: WARMING PIPE TO ASSEMBLE FITTINGS: Polyethylene pipe may develop some ovality from storage and in cold weather it may be necessary to warm the pipe to enable the insertion of a fitting or the assembly of a compression fitting. To warm polyethylene pipe DO NOT USE A TORCH TO HEAT THE PIPE and never heat the plastic above 2000 F. The recommended method for warming the pipe is immersion in hot water or warming with a hair dryer. Use care to warm the inside of the pipe was well as the outside, never heat the outside of the pipe only. Polyethylene does not become brittle when subjected to extremely low temperatures, but does become much stiffer. The workability of polyethylene increases with higher temperatures. The heavier the wall thickness of the pipe or tubing being used the more stiffness will be encountered in cold weather. It is recommended that the pipe or tubing be kept in a warm environment prior to installation outdoors in the winter months to keep it as flexible as possible. LUBRICATION AND SEALING COMPOUNDS: The use of any type of lubricant including detergent or soap lubricants to ease the insertion of the pipe or tubing into a fitting voids all warranties on the pipe. Detergents, soap and surfactants may cause stress cracking in polyethylene and should never be used. Endot does not recognize any pipe dope or sealing compound as acceptable for use with Endot polyethylene pipe or tubing, regardless of manufacturer's claims. All pipe sealant and dope may cause stress cracking in polyethylene and should never be used. The use of any pipe dope or sealing compound voids all warranties. APPLICATION NOTES SITE PREPARATION: When polyethylene pipe or tubing is to be installed in a trench site preparation is important. Pipe must be surrounded with a bed of sand or other backfill material that is 1/2" or less in diameter and is free from rocks, sharp objects and debris that might puncture the pipe. The base of the trench must be lined first with sand and the pipe uniformly and continuously supported for its entire length. Pipe should be placed at a depth at least 12 inches below the local frost line and a minimum of 18 inches below the finished surface grade for light loading and at least 24 inches for sites with heavy loading. Trenches may be curved to avoid obstacles with the minimum trench radius being 24 inches. Polyethylene's natural flexibility allows it to be routed around objects to eliminate fittings. ASTM D2774, F645-95 and ASTM D2321 cover the installation and site preparation for polyethylene pipe and tubing in detail and should be followed by installers. Check with you local code officials to determine specific local requirements. THERMAL EXPANSION AND CONTRACTION: Polyethylene is stable in its cross section dimensions, but can expand and contract longitudinally with changing temperatures. Allowing polyethylene pipe to naturally "snake" in a trench will provide adequate slack to compensate for this expansion and contraction. A minimum 12 inches of slack per 100 feet of pipe must be allowed to compensate for thermal changes. INSTALLATION IN CONTAMINATED SOILS: Hydrocarbon fuels, certain organic solvents and a few other chemical compounds can have a serious negative effect on polyethylene if present in sufficient quantity. Water carried in any piping system is vulnerable to contamination by absorption of chemicals through the walls or joints. Water lines produced from any material should not be installed in areas when known chemical contamination is present or if chemical spills are likely to occur. See a chemical resistance chart to determine if a particular chemical has any negative effects on polyethylene pipe and tubing. PRESSURE TESTING OF INSTALLATIONS: All installations must be pressure tested prior to backfilling. Check all joints and connections for leaks before backfilling the trench. ASTM D2774 and The Plastic Pipe Institute technical reference #TR-31/88 provides detailed testing information. Pressure tests must be made using water, Do Not pressure test with air. It is the users responsibility to select the proper fitting and to ensure the assembly is correct and leak tight. All joints must be pressure tested prior to backfilling. Endot assumes no liability for the improper installation of any fitting nor the failure to test the joint prior to backfilling a trench. CRIMPING PIPE TO STOP FLOW: The use of crimping tools to shutting off flow in polyethylene pipe is acceptable. It is critical that the crimping tool used meets the following criteria: 1) The tool is specifically designed for use with polyethylnene pipe. 2) The tool is set up for, or uses adaptors to match the size (OD) of the pipe. Using a tool designed for smaller diameter pipe on larger diameter pipe will damage the pipe and require replacement of that section of pipe. 3) The tool is only used once on a specific place on the pipe. A pipe once crimped should never be crimped in the same place again. 4) Following crimping the same tool can be used to re-round the pipe to provide full flow capacity to the line. APPLICATION NOTES INSTALLING PIPE USING DIRECTIONAL BORING EQUIPMENT: Endot pipe and tubing may be installed using directional boring equipment. The boring tool should create a hole that is 25% larger than the outside diameter of the pipe or tubing to allow the pipe to pass through the soil without being abraded or subjected to excessive tension. All bends and changes in elevation should be within the guidelines established for polyethylene pipe and tubing. Pipe or tubing installed with directional boring equipment must not be subjected to tensions greater than the tensile strength of the product being used. Excessive tension can cause damage to polyethylene pipe. The nominal tensile strength of 200 PSI, PE 4710/PE 3408, 3/4" and 1" pipe (IPS) and tubing (CTS) is as follows; ASTM D2239 Pipe (IPS) 3/4" 1" 1200 PSI 1900 PSI ASTM D2737 Tubing (CTS) 800 PSI 1300 PSI In some soils it may be necessary to grout the bore hole to prevent collapse prior to installation of the pipe. Grouting will maintain the hole and reduce friction that could damage the pipe. Endot will not be responsible for damage to the pipe when boring takes place in soils that do not maintain a open hole during pipe installation or that contain sharp rock or debris that cut or scrape the pipe causing damage that may reduce the wall thickness. NOTE: Pipe laying in sun light can increase significantly in temperature often to temperatures as high as 140 o F. If pipe is bored at elevated temperatures it is possible that the pipe will stretch or elongate. If the pipe stretches greater than 5% the pipe is damaged and may not be capable of carrying it’s rated pressure. Endot will not warranty pipe that has been stretched greater than 5%. APPLICATION NOTES WELL PIPE INSTALLATION: Polyethylene pipe is an ideal product for use in both deep and shallow well applications. See the Depth Setting Chart for a guide to the depth settings that various grades of pipe can be used at. Although claims for deeper settings have been made they exceed the design ratings for all Polyethylene pipe and the installer risks rupturing the pipe if the pressure developed by the column of water and the pump pressure exceeds the pressure rating of the pipe. No warranty claims for depths greater than those listed will be honored. The actual installation includes the use of insert fittings and stainless steel clamps as previously covered. Torque arrestors and centering devices should be used to prevent the pipe and wires from rubbing the well casing. The installation of torque arrestors and other well hardware should be per the manufacturer instructions. If the pipe has a submersible pump suspended on it a safety rope must be installed to assist in pulling the pump. When a long length of pipe is pulled from a well care must be taken to prevent kinking of the pipe. The maximum bend radius of polyethylene pipe is 18 inches. If the pipe is kinked the section must be removed since a weak point has been created at the kink. OTHER USES: Polyethylene pipe and tubing is used in many other applications. Lawn Irrigation is one of the more popular uses. Generally the pipe is plowed into the ground without preparing a trench. This method works well if the soil is free of rocks and other sharp objects. The denser the soil the more difficult this method of installation can become due to the increased tension placed on the pipe. The use of heavier walled pipe can overcome some of these problems. For above grade applications Endot recommends the use of black pipe or tubing. Endot produces EndoPure, blue pipe and tubing, which is Ultraviolet stabilized, but all colored HDPE pipe and tubing has a finite life and should not be installed where continuously exposed as in above ground installations. Endot EndoPure has been tested for a five (5) year life span without fading or UV damage in the Florida latitude. High Density Polyethylene is a very stable plastic compound allowing the use of pipe manufactured from it to be used in numerous applications. Before attempting to use polyethylene in applications other than for transport of water one should check with an knowledgeable source to determine if the product is suitable. Certain chemicals may soften polyethylene and can degrade its ability to withstand internal pressure. If the polyethylene pipe is to be used to transport chemicals or chemicals are present in the pipe environment it is the responsibility of the user to determine if the chemicals are compatible with polyethylene pipe.

Consult Endot APPLICATION NOTES ICE SKATING RINKS Polyethylene (PE) pipe is a cost effective product for use in the construction of ice skating rink freezing systems. PE is up to 5 times less expensive than steel pipe and eliminates the need for costly skilled labor to weld numerous joints. The labor savings using PE can be up to 75% of a steel pipe installation. PE can be produced in extra long coils of up to 1000 feet or on wooden reels of up to 7500 feet thus eliminating joints and further reducing installation cost. The total time of installation can be reduced when using PE due to PE's light weight and flexibility. PE is abrasion resistant and can be encased in a concrete or sand base with no concern as to corrosion or other damage. Care in handling must be observed during shipping, storage and installation to prevent punctures from sharp objects. PE is nearly chemically inert and is suitable for use with brine and ethylene glycol solutions. See the Chemical Resistance Chart for details on specific chemicals. The Heat Transfer K Value for High Density Polyethylene is 2.5. (2.5 BTU/hr/oF/f2/f) INSTALLATION SUGGESTIONS Inspect all pipe prior to installation for damage such as kinking, cuts or abrasions. Do not use pipe that is damaged. The base upon which the pipe will be installed should be uniform, smooth and free of sharp objects. If insert fittings are used they should be located outside of the actual ice area for ease of service. Long lengths of pipe facilitate this method of installation. All clamps must be stainless steel and two clamps should be used on each side of a fitting. (See Joining Pipe with Insert Fittings) Pipe can also be joined using thermal fusion for even greater reliability. Follow the fusion equipment instructions carefully. Installed pipe must be protected from damage prior to embedment. Do not allow wheelbarrows and other equipment to travel over the exposed pipe. The entire system must be pressure tested with water to 150% of system working pressure prior to embedment. DO NOT PRESSURE TEST WITH AIR. APPLICATION NOTES CONCRETE SLAB INSTALLATIONS & RADIANT HEATING Endot polyethylene (HDPE) pipe and tubing are versatile products that are ideal for installing potable water systems and radiant heating systems especially when these systems are installed in a concrete slab. Using HDPE will provide a system that is superior to metal piped systems. The primary advantage of HDPE pipe or tubing in a concrete slab installation is CORROSION RESISTANCE. Concrete is a highly alkaline material and this alkalinity will rapidly corrode copper pipe and tubing whereas HDPE is unaffected by this alkalinity. Endot PE pipe is nearly chemically inert and provides a system with exceptional longevity.

Consult Endot APPLICATION NOTES FORCE MAIN SEWER SYSTEMS Endot recommends that only pipe and tubing made from NSF Certified resin be used in a sewer application. Endot’s NSF CERTIFIED PE-4710/PE-3408 pipe and tubing are versatile products that are ideal for transport of waste water and sewage in force main sewer systems. NSF Certified resins assure the pipe and tubing is capable of withstanding various chemicals that might be found in waste water that will cause stress cracking of lower quality resins. NSF Certified resins are also pressure rated, a critical issue with force mains. Using NSF CERTIFIED resin will provide a system that is superior to metal piped systems. The resin used to produce pipe and tubing for a force main sewer system should carry a minimum cell class rating of 445574C according to ASTM D3350. (NOTE: “C” = black resin, if colored pipe is produced the letter must be “E” which equals colored with UV Stabilizers.) NSF CERTIFIED pipe and tubing is pressure rated and able to handle the pressure of grinder pumps. Endot’s NSF Certified resins carry a Hydrostatic Design Rating from the Plastic Pipe Institute assuring the ability to withstand pressure for 50 to 100 years of service. (NOTE: Non-NSF Certified resins are not likely to be pressure rated and questionable for use in a pressurized system.) Endot NSF CERTIFIED PE-47/PE-3408 pipe is nearly chemically inert and provides a system with exceptional longevity. (See Chemical Resistance Chart) Non-NSF resins may not be resistant to chemical attack that causes stress cracking. INSTALLATION EASE: Endot NSF CERTIFIED pipe is lightweight, flexible and available in extra long continuous lengths for faster, joint free installations. TOUGH AND DURABLE: Endot NSF CERTIFIED pipe can endure the punishment of the most demanding installation. Produced from the highest quality polyethylene resins available Endot pipe can be buried with confidence it will perform for many years. SUPERIOR FLEXIBILITY: Endot NSF CERTIFIED pipe can be installed in long continuous lengths and NSF CERTIFIED coiled pipe can be cold bent to a minimum radius of 10 to 20 times the nominal pipe diameter to provide for contouring to installation conditions. Ordinary shifting and settling of soil will not fracture or shear the pipe. Handling on the job site is not as difficult as PVC and other products that can be brittle and subject to breakage if dropped or accidentally hit by equipment. SUPERIOR CRUSH RESISTANCE: Endot PE pipe is extremely strong and will withstand high load conditions without fear of collapse or damage. NOTE: NSF Certified resins are repeatable in characteristics such as flexibility, pressure rating, crush resistance etc. Non-NSF resins are not likely to be consistent in these characteristics.
