Laminated & Plastic Fittings

Steel pipe inadequacies in severe chemical applications led to the development of plastic lined steel. However, without any bonding to the steel, the normal characteristics of plastics such as creep, high thermal contraction and expansion, plastic memory and lower strength lead to mechanical failure of the lining. Dual laminate piping can be used in full vacuum, at higher temperatures and weighs approximately 75% less than lined steel. Additionally, any external corrosion due to exposure to industrial environments is avoided. Unlike thermoplastic pipe, dual laminate pipe will retain its pressure rating even with temperature increases. The allowable support spacing is almost twice that of thermoplastic pipe and dual laminate pipe is rarely subject to brittle fracture at low temperatures.
