Profile: Plastic lined piping combines both common piping systems, metallic and nonmetallic piping, into one. We provide the chemical resistance of plastics, fluoropolymers, and the inherent strength of steel, or alloy metallic piping systems. Our loose liners provide a space for gas build-up between the plastic liner and the steel pipe. Our bonded plastic lined pipe can operate at full vacuum. We offer the most complete lining capability.
