Polypropylene (PP) lined pipe is our most economical option for industrial fluid handling. PP lining delivers excellent resistance to acidic and basic fluids, and can handle temperatures up to 225˚F (110˚C). However, it does not handle solventsand VOCs well, and can become brittle in low temperatures. Typical uses for PP-lined piping include water treatment, chemical processing, and power generation. PP-lined piping is also a popular choice for use in food and beverage manufacturing, processing and packaging.

ATL PTFE-Lined Pipe and Fittings

Resistoflex ATL PTFE piping is a highly specialized variant on conventional PTFE-lined piping that has been designed to reduce permeation rates by up to 60%. Made from specially formulated resins, ATL PTFE liners deliver optimal crystallinity and strength, even in severe service applications. As a result, they can withstand exposure to both aggressive chemicals and high temperatures. For more information and detailed product specifications, contact SEMCOR directly.

PVDF-Lined Pipe and Fittings

PVDF lined pipe — also known as Kynar® — is extremely tough and durable, with superior abrasion resistance compared to other types of lined piping. It has a high thermal expansion coefficient and is suitable for use with halogens and high-strength acids. As a result, Kynar-lined piping is often used for pulp and paper manufacturing, chemical processing and electronics manufacturing. It is less suitable for processes involving pH levels higher than 11, or temperatures above 275°F (135°C).

For all of the above products, we carry an extensive supply of pipe fittings and accessories. Let us put together a complete package containing everything you need for your application.
