Steel-Plastic Composite Pipe | Coated Plastic & Lined Plastic Composite Steel Pipe for Water Supply & Drainage

Steel-plastic composite pipe is a composite pipeline product that combines the mechanical strength of steel pipe and the anti-corrosion performance of plastic, mainly including coated plastic composite steel pipe, lined plastic composite steel pipe and short-pitch internal spiral steel-plastic composite pipe for building drainage.

Our products strictly implement national and industry standards, with complete specifications ranging from DN15 to DN3400, meeting the pipeline needs of fire protection water supply, construction water delivery, chemical fluid transportation, municipal engineering and other fields.

Excellent Corrosion Resistance
The inner plastic layer isolates fluid from the steel pipe, effectively resisting acid, alkali, salt and sewage corrosion, and extending service life.

High Mechanical Strength
It retains the impact resistance, compression resistance and bending resistance of steel pipe, suitable for buried, overhead and heavy-load engineering environments.

Smooth Inner Wall & Low Fluid Resistance
The smooth plastic inner wall reduces pipeline scaling, improves water delivery efficiency, and avoids pipeline blockage.

Wide Specification Coverage
Specifications cover from small-caliber DN15 to large-caliber DN3400, and customized processing is supported to meet various engineering needs.

Strict Standard Compliance
Our products comply with GB and CJ/T national and industrial standards, with stable quality and convenient engineering acceptance.
