Plastic-lined steel pipe bonds a corrosion-resistant plastic liner to a structural steel outer pipe. The economical answer for services that are corrosive first and abrasive second — acid, alkali and salt slurries, desulfurization systems.
Liner materials: PE for general chemical service, PP for higher temperatures, PTFE for aggressive chemistry.
EverWear Pipe (Cangzhou Ruicheng Pipeline Equipment Manufacturing Co., Ltd., founded 2014) produces plastic-lined steel pipe in Yanshan Economic Development Zone, Cangzhou, Hebei, China.
Technical Features
- Steel strength, plastic chemistry. Each material does what it does best.
- Liner matched to the medium. PE / PP / PTFE selected for your specific service.
- Continuous protection through fittings. Elbows, tees, reducers lined alike.
- Smooth, low-friction bore. Resists scaling and build-up.
- Economical vs. solid alloy. Far less than stainless for equivalent corrosion service.
- Cut-to-length and flanged to drawing. Ready to bolt up.

FAQ
1. Which liner material suits my service?
Depends on medium, concentration and temperature — send service conditions for recommendation.
2. Plastic lined vs. stainless steel — which is cheaper?
Plastic-lined carbon steel is typically the economical choice for moderate temperatures/pressures.
3. What temperatures can it handle?
Depends on liner: PE moderate, PP higher, PTFE highest. Confirm before quoting.
4. Are fittings lined too?
Yes — elbows, tees, reducers with liner carried to flange face.
5. What do you need for a quotation?
Diameter, lengths, liner material (or medium/concentration/temperature), flange standard, quantities.
