Polyethylene plastic steel winding pipe

Polyethylene-plastic-steel winding pipe (SRWPE) is made of steel-plastic composite special-shaped strip through spiral winding welding (extrusion welding on the lap joint), and its inner wall is smooth and flat, and the specifications are DN200-DN2600mm. This kind of pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate, long life (50 years), etc. It can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), and is an environmentally friendly green product.

Features:

1 Safe and reliable ring stiffness Compared with pure plastic pipes, the reinforced steel strip is very easy to make pipes, especially large-diameter pipes, have enough safe and reliable ring stiffness 2 The inner wall is smooth, and the flow resistance is 20~30% lower than that of cement pipes. Polyethylene (PE) The inner wall of the pipeline is smooth, the friction coefficient is small, and the sediment is not easy to accumulate in the pipeline, and the friction resistance is almost unchanged after long-term use 3 Flexible or leak-free (electrofusion welding, butt welding) connection, good sealing performance and environmental protection performance Both sealing connection methods can be operated manually with simple tools, no need for machinery, very simple and fast, reliable and leak-free4 Corrosion resistance, service life of more than 50 years High-density polyethylene (PE) pipeline service life can be as long as 50 years5 Quality Light, few joints, no need for large equipment, easy installation and laying, light weight, no need for large lifting equipment during installation. Good axial flexibility, low requirements for the flatness and firmness of the bottom of the groove during laying, and strong ability to withstand abnormal stress caused by improper installation 6. On-site production, greatly saving transportation costs ) transportation, the pipe winding device is simple and compact, which is convenient for manufacturers to transport the device to the vicinity of the construction site, and the nearby winding production and supply of pipes greatly reduces the transportation cost of users. 7. Strong resistance to abnormal sudden load. The pipe can resolve the resulting stress through elastic deformation, and avoid leakage or damage at the pipe joint due to excessive stress and deformation. The comprehensive cost is competitive. The advantages of the material are combined, and the pipe has excellent comprehensive performance.
