Hdpe Water Pipe Manufacturer in China
HDPE water pipes are pipes made of high-density polyethylene material. The material has higher strength and density than low-density polyethylene due to its molecular structure, which has higher linearity and fewer branches. HDPE is a thermoplastic that can be softened and formed by heating and fixed in shape after cooling, which makes it very suitable for manufacturing various types of pipes.

Key Features of HUALIN Hdpe Water Pipe
Hdpe water pipes have excellent physical properties and chemical stability. They are not only strong and pressure-resistant, but also have good flexibility and impact resistance, and can be used safely in complex terrain and harsh environments. The inner wall of HDPE water pipes is smooth, with low water flow resistance and high transmission efficiency. At the same time, they have excellent corrosion resistance and can effectively resist the erosion of acids, alkalis and various chemicals in the soil. The service life can reach more than 50 years. High-density polyethylene water pipes are light in weight and easy to install. They can be connected by hot melt or electric melt to ensure reliable sealing of the joints and reduce the risk of leakage.

HDPE Water Pipe Connection Technology
The common connection methods of HDPE water pipe connection technology include hot-melt butt, electric-melt connection and mechanical connection. Among them, hot-melt butt is to heat the end face of the pipe to melt it, and then fuse and cool it under pressure to form an integrated joint, which has the advantages of good sealing and high strength; electric-melt connection is to use electric-melt pipe fittings with embedded resistance wire to heat and fuse two sections of pipes, which is easy to operate and suitable for connecting pipes of different diameters. In addition, mechanical connection methods such as flanges and steel-plastic transition can also be used to facilitate connection with valves or other material pipeline systems.
Main structural types and applications of HDPE water pipes
| type | Structural features | Typical application scenarios | Performance Advantages |
| Wire Mesh Skeleton Composite Pipe | HDPE+steel wire reinforcement, two-color composite layer | High pressure water supply (≤1.6MPa) | Ring stiffness SN8-SN16, anti-foundation settlement |
| Double wall corrugated pipe | The outer wall is corrugated to resist pressure, and the inner wall is smooth | Municipal drainage/rainwater collection (DN3000) | Pressure-resistant and impact-resistant, easy to construct |
| Steel belt reinforced spiral pipe | HDPE+corrugated steel belt “V” reinforcement | Deep buried sewage discharge (covering soil> 8 meters) | Ring stiffness reaches SN20, deformation rate <3% |
| Seamless outer insulation pipe | HDPE outer layer + thermal insulation interlayer | Heating network (medium ≤ 120℃) | Resistant to environmental stress cracking and strong sealing |
