Hole net steel strip polyethylene composite pipe is a composite material pipe that uses cold-rolled steel strip welded hole net pipe as the reinforcing frame, and is compounded with thermoplastic plastics. Below is a detailed introduction to it:

Structure and Principle

The steel frame of the steel-bonded polyethylene composite pipe on Kongwang is formed by rolling and welding after perforating the steel strip. The reinforced frame and the plastic interlock to form an integrated unit, with the plastic layers on both the inner and outer walls almost impossible to peel off. The composite layer contains no adhesive, combining the benefits of steel and plastic pipes.

Performance Features

High strength and pressure resistance: Thanks to the steel strip reinforced frame, the pressure resistance of the pipe material is significantly improved, enabling it to withstand greater pressure and external loads.

Corrosion and wear resistance: The plastic layer on both the 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, non-scaling, water head loss 30% lower than steel pipe, and meets relevant hygiene standards, suitable for drinking water transportation.

Long service life: Up to 50 years under normal conditions.
