Water Conservancy & Fire Protection

In compliance with well-established domestic and international standards, we manufacture high-quality water supply, drainage and fire protection pipes that meet technical requirements on diameter, material, wall thickness, anti-corrosion type and connection method. Our products are tailored to various construction environments, pressure conditions, project types and other on-site operating factors.

Product Features

High strength, non combustible, stable

The base pipe is made of steel pipe, featuring high mechanical strength and non-combustibility with stable pressure bearing performance. Steel pipes of different materials, wall thicknesses and processing technologies can be selected according to the conveying pressure of different media to adapt to diverse working conditions.

The installation is flexible and convenient

A variety of connection methods including threaded joint, grooved joint, flange joint, welding and socket joint are available for pipes of different diameters and actual application scenarios such as pipe gallery, underground laying, overhead installation, hoisting and shaft installation. The installation is flexible and convenient.

Corrosion and scaling resistance

Anti-corrosion steel pipes, especially food-grade epoxy resin plastic-coated steel pipes, deliver excellent corrosion resistance and anti-scaling performance. They prevent secondary water pollution and blockage of sprinkler systems caused by precipitate inside pipes.

Smooth inner wall

The smooth inner wall of epoxy resin plastic-coated steel pipes reduces frictional resistance, effectively cuts down hydraulic loss during operation and lowers overall operating costs.
