It depends on the chemical solution, temperature of service and the abrasive nature of the particles flowing through the system. Abtrex will work with you to decide which abrasion and corrosion control system is appropriate for your individual processes.
The condition or the interior substrate will determine the suitability of adding linings to existing tanks/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.
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.
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 equipment and surrounding area.
Abtrex has facilities in Indiana, Pennsylvania, Texas, and Alabama. Our crews have worked throughout North America and as remotely as China, Brazil, Norway, Korea, Germany, Poland 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).
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
