coating process involves the use of dip tanks that
contain a solution of nickel, phosphorus, or hydrochloric
acid. During a recent inspection, the tanks themselves
showed signs of corrosive attack, so a call was made to
Nilex.
After an initial site visit, Nilex provided several liner
options. Maintenance-free tank operation and long
service life were desired, so Nilex installed a polymeric
liner equal to the task.
Challenge
A tank’s durability and total lifecycle often depend on
the influence of its primary adversary: corrosion. Harsh
chemical reactions in process tanks generate significant
corrosion, so material selection and quality control were
crucial in this application.
Solution
Although the customer considered various companies,
Nilex was chosen for the following reasons:
•
Extensive tank lining experience
•
Long geomembrane service life
Summary
•
Spark testing capabilities to ensure liner integrity
The customer, Harber Coatings, specializes in protecting
industrial parts against corrosion and abrasion. Their
•
Production schedule that satisfied customer’s
expectations
HYDROCHLORIC ACID LOOSE-FIT LININGS
The customer also considered an alternative product, a
rubber lining, but chose Enviroflex Linear Low Density
Polyethylene (LLDPE) geomembranes instead because
polymeric linings provide rubber-like performance at a
much lower cost than rubber or spray coatings.
Results
Storage and process tanks are only as good as their
liners. The better the liner, the longer a tank lasts.
Without functioning process tanks, the customer suffers
expensive and unwanted downtime.
Nilex assisted with onsite API 653 consulting, product
and technical support and efficient installation
turnaround, quickly restoring Harber’s operation.

Installation
Nilex’s Enviroflex LLDPE geomembranes have the ability
to conform to irregular surfaces, offer greater resistance
to stress cracks and facilitate easier welding. This
increased flexibility makes Enviroflex geomembranes
well suited to pre-fabrication into large panels,
minimizing field work, therefore a very quick turnaround
was achieved (and required by the customer).
A four-man crew spent a total of 64 man-hours on
installation.
