Frequently Asked Questions

Questions About Rubber Lined Pipe? We’ve got answers!

 

Do I need linings or coatings in my piping system?
It depends on the chemical solution, temperature of service and the abrasive nature of the particles flowing through the pipeline. Abtrex can be your pipe lining solution expert that will work with you to decide which abrasion and corrosion control system is appropriate for your individual processes.
Can you line used or existing pipe that is already in service?
The condition or the interior substrate will determine the suitability of adding linings to an existing pipe. Abtrex can inspect your existing equipment to determine if you need newly fabrication and rubber lined systems. We also specialize in field services that may allow your systems to be refurbished.
What is the best lining solution for my pipe?
A multitude of factors determine which lining solution is best for your application. Temperature, PH levels, flow velocity and particle size can all determine what type and thickness of material is recommended for your equipment.
What is the turnaround time to rubber line pipe and what will it cost?
Unfortunately, there is not one simple answer to cover every situation and configuration. However, with sufficient information, Abtrex staff can quickly provide budget pricing and time estimates. Our sales engineers and project managers can help create a plan that will minimize downtime. Some factors effecting turnaround and pricing are:

– Rubber compound being applied (natural, neoprene, nitrile, etc.)
– Surface preparation required (eg. strip and re-line versus new construction)
– Access to the tank and surrounding area.

What geographic region does Abtrex serve?
Abtrex has facilities in Michigan, Indiana, Pennsylvania, Texas and Cambridge, Ontario. Our crews have worked throughout North America and as remotely as China, Brazil, Norway, Korea, Germany and Mexico.
I've used other lining and coating systems that have delaminated or flaked off prematurely. What is the bonding strength of rubber lining?
Most rubbers manufacturers list the adhesion to metal at 25 to 30 pounds. Abtrex rubber linings consistently surpass the manufacturers’ specifications and have achieved results of 50 to 60+ pounds using ASTM D429 method B (90° stripping test).
What are the advantages of vulcanization?
Rubber is comprised of long polymer chains. These chains can move independently of each other, distorting the material. Vulcanization crosslinks the chains and prevents this movement. Basically, vulcanized rubber has a memory; it will distort under stress, but will return to shape after the stress is removed.

Other benefits are:

– Better adhesion to substrate
– Higher strength/durometer (hardness)
– More stable
