Plastic coated composite pipes are steel pipes coated with epoxy or polyethylene layers (200–500 μm) to combine the strength of steel with the corrosion resistance of plastic. They offer excellent durability, smooth internal flow, and pressure resistance up to 2.5 MPa, making them ideal for water supply, fire protection, and industrial pipeline systems.
