Hole steel belt polyethylene composite pipe is a composite pipe material with a reinforced skeleton made of cold-rolled steel strips welded into a perforated pipe, and is compounded with thermoplastic plastics. Below is a detailed introduction to it:

Structure and Principle

The steel frame of the steel belt polyethylene composite pipe on Kongwang is formed by rolling and welding after punching the steel strip. The reinforced frame is integrated with the plastic, making the inner and outer plastic layers almost impossible to剥离. There is no adhesive in the composite layer, combining the advantages of steel and plastic pipes.

Performance Features

High strength and pressure resistance: With a steel strip reinforced frame, the pipe material's pressure resistance is significantly enhanced, capable of withstanding greater pressure and external loads.

Corrosion and wear resistance: The plastic layer on both inner and outer walls provides excellent corrosion resistance, effectively resisting erosion from acids, alkalis, salts, etc., and boasts good wear resistance, about four times that of steel pipes.

Excellent impact resistance: High ring stiffness and impact resistance, capable of adapting to complex construction and usage environments.

Low linear expansion coefficient and thermal conductivity: Possesses the characteristics of low linear expansion coefficient of steel pipes, with a low thermal conductivity, and good thermal insulation performance.

Good hygiene: Interior wall smooth, no scaling, water head loss 30% lower than steel pipe, and meets relevant hygiene standards, suitable for drinking water conveyance.

Long lifespan: Up to 50 years under normal conditions.
