Composite Pipe
Plastic-Coated Composite Pipe
Steel pipe fused with internal and external plastic layers for corrosion resistance, clean flow, and easier installation.
Overview
Built for the application, not just the catalog
This product family covers polyethylene-lined, epoxy-lined, and other composite configurations according to the service condition. Joint preparation and fittings are available to keep the installed system reliable.
It is often used where conventional carbon steel pipe would require frequent maintenance or where water quality standards demand a clean interior.
