The polyethylene-plastic steel coiled pipe (SRWPE) is made of steel-plastic composite profiled strip by spiral wound welding (extrusion welding on the lap joint), and its inner wall is smooth and flat, and the specification is DN200-DN2600mm. The pipe has the advantages of corrosion resistance, light weight, simple installation, large flow rate and long service life (50 years). It can replace the pipe made of high energy consumption materials (cement, cast iron, ceramics, etc.) and is an environmentally friendly green product.

HDPE plastic steel winding pipe is a high-tech composite pipe product with independent intellectual property rights, world leading level, green environmental protection, energy saving and consumption reduction. The product is mainly used as a buried drainage pipe, which integrates the rigidity of the steel strip and the corrosion resistance of the polyethylene, the low frictional resistance and the anti-wear.

No. Features Details

1 Safe and reliable ring stiffness Compared with pure plastic pipe, the reinforced steel belt makes it easy to make the pipe, especially the large diameter pipe, safe and reliable.

2 The inner wall is smooth and the flow resistance is 20~30% lower than that of the cement pipe. The inner wall of the polyethylene (PE) pipe is smooth, the friction coefficient is small, and the sediment is not easy to accumulate in the pipe. The friction is almost unchanged after long-term use.

3 Flexible or leak-free (electric welding, butt welding) connection, good sealing performance and good environmental performance. Both sealing connections can be manually operated by simple tools, no need for machinery, very simple and fast, and reliable and leak-free.

4 Corrosion resistant, service life over 50 years High density polyethylene (PE) pipeline life can be up to 50 years

5 Light weight, few joints, no need for large equipment, easy installation and installation, light weight, no large lifting equipment required for installation. The axial flexibility is good, the flatness of the bottom of the groove is required during laying, the requirement of firmness is low, and the ability to withstand abnormal stress caused by improper installation is strong.

6 Strong resistance to abnormal sudden load The pipe can be elastically deformed to resolve the resulting stress, avoiding leakage or damage due to excessive stress and deformation at the pipe joint.

7 Comprehensive cost competitiveness The advantages of combining two materials of steel and plastic, the pipe has excellent comprehensive performance.
