Steel Wire Reinforced Thermoplastics Composite Pipe

Intro

The Steel Wire Reinforced Thermoplastics (PE) Composite Pipe is abbreviated as SRTP, which is a kind of high-strength plastic steel wire wound in the pipe as the reinforcement, and the outer layer and the inner layer are compounded with thermoplastic high-density polyethylene on both sides, which is compounded by extrusion molding method. New environmentally friendly plastic composite pipe. It not only overcomes the respective shortcomings of steel pipes and plastic pipes, but also has excellent pressure-bearing performance of steel pipes and good hygiene performance of plastic pipes.

The steel mesh skeleton polyethylene composite pipe has a three-layer structure, namely the core pipe, the steel wire layer, and the outer PE layer. The core tube and the steel wire winding layer are used to withstand the internal pressure of the pipe, and the outer PE layer is mainly used for welding connection.

Both the core tube and the outer PE layer are made of PE80/PE100 grade raw materials, and the steel wire winding layer is made of HDPE modified material and steel wire. The modified HDPE and HDPE can be melted together under heating conditions.

Performance & Advantages

1. Good corrosion resistance

   Compared with metal pipes, steel-framed polyethylene plastic composite pipes, like PE pipes, have excellent chemical corrosion resistance, and have good corrosion resistance to more than 270 corrosive media such as acids, alkalis, salt solutions, and organic solvents.

2. Good anti-wear performance

   The wear resistance of steel frame polyethylene plastic composite pipe is 3 times that of steel pipe

3. Smooth inner wall and low conveying resistance

   The steel skeleton polyethylene plastic composite pipe adopts the internal shaping process, and its inner surface is smoother than the inner wall of the plastic pipe. The equivalent absolute roughness is 0.01mm, while the equivalent absolute roughness of the inner surface of the steel pipe is 0.2mm. The steel pipe has been significantly improved.

4. Good toughness

   The steel-framed polyethylene plastic composite pipe has a moderate elastic modulus, which is 4 times that of polyethylene pipes and one-sixtieth that of steel pipes, indicating that the product has moderate toughness and inherits the characteristics of polyethylene flexible pipes, which is convenient for Excavation construction and slope laying, reduce construction costs.
