DN300 Sewage Pipe Drain Pipe HDPE Reinforced Double Wall Bellows

The DN300 Sewage Pipe Drain Pipe HDPE Reinforced Double Wall Bellows is a new type of steel-plastic composite gravity flow pipe. It is manufactured through the welding of special composite strips, which allows it to fully combine the merits of ordinary pressure plastic pipes (such as flexibility) and high-strength steel ribs (such as structural stability). This dual advantage enables the pipe to meet all requirements of relevant projects, making it a preferred choice for transporting both corrosive and non-corrosive media via gravity flow.

Feature:

1.Strong Compression Resistance and Impact Tolerance

The reinforcement layer made from steel strips notably boosts the pipe’s ring stiffness and enhances its ability to stand up to impacts. This feature allows the pipe to adjust well to different ground conditions when used in practical scenarios.

2.Excellent Hydraulic Efficiency

Our steel belt reinforced HDPE corrugated pipe has a smooth inner wall, and this design helps reduce frictional resistance when fluid flows through it. When compared with concrete pipes of the same inner diameter, this structure makes the pipe’s flow capacity go up by over 40%.

3.Good Chemical Resistance

This type of pipe can resist the erosion of various chemicals, including acids, alkalis, and salts. Such a property makes it a perfect choice for wastewater discharge tasks in different types of soil environments.

4.Outstanding Abrasion Resistance:

The inner surface of the pipe is smooth, which helps reduce scaling to a minimum. As a result, it has a longer service life compared with steel, cast iron, or concrete pipes.

5.Ease of Installation:

No temperature restrictions; low requirements for foundation treatment. Lightweight, flexible, and compatible with multiple jointing methods.

Applications:

1.Municipal Engineering

2.Underground drainage, sewage, and ventilation systems.

3.Electrical and Telecom Engineering

4.Protective casing for power cables and communication optical fibers.

5.Agriculture irrigation systems for farmland and forestry.
