PE-X/Steel/PE-X Pressure Pipe Production Line

Development Background of PE-X/Steel/PE-X Multi-layer pressure pipe

Associating the requirements from market, Guangzhou Advance-Tech Co., Ltd began to develop plastic-steel-plastic (PE-X/Steel/PE-X) multi-layer pressure pipe technology in 1998, and successfully developed this technique in 2000.

Through large quantities of developments and practices, Guangzhou Adance-Tech Co., Ltd has solved the problems of adhering of various steel strips to plastic, and butt welding and forming of thin wall steel strips. Through joint efforts of Guangzhou Advance-Tech Co., Ltd and Xinxing Ductile Iron Pipes Co., Ltd for many years, PE-X/Steel/PE-X multi-layer pressure pipe became one of the advanced pipes following the PE-X/Al/PE-X multi-layer pipe, which combines the advantages of metal and plasti. PE-X/Steel/PE-X multi-layer pressure pipe has been being applied in China, South East Asia, South America, etc.

Introductions for PE-X/Steel/PE-X Pressure Pipe

PE-X/Steel/PE-X multi-layer pressure pipe is a kind of new structural multi-layer pipe originated by Guangzhou Advance-Tech Co. Ltd and improved over and over again for many years. The PE-X/Steel/PE-X multi-layer pressure pipe takes HDPE as the inner and outer layers, continously butt weledd thin wall steel pipe as the middle layer. Special thermosol is used to adhere ech layer together. The whole forming and extrusion process is continuous, so each layer of the PE-X/Steel/PE-X pressure pipe are integrated together combining the advantages of metal pipe and plastic pipe. The wall thickness of the PE-X/Steel/PE-X pressure pipe is thiner than that of the plastic pipe, but the pressure-bearing of PE-X/Steel/PE-X pressure pipe can up to 2.5Mpa (25bar). The PE-X/Steel/PE-X pressure pipe’s rigid is very good.

The PE-X/Steel/PE-X pressure pipe technology has been applied and tested in various domains and regions in China, and is accepted by end users and construction units. The Chinese government has approved the Standard and Construction Specification for PE-X/Steel/PE-X Pressure Pipe jointly compiled by Guangzhou Advance-Tech Co., Ltd and Xinxing Ductile Iron Pipes Co., Ltd. Many PE-X/Steel/PE-X pressure pipe manufacturers in advanced countries refer to this standard and introduce technology from Guangzhou Advance-Tech Co., Ltd.

Characteristics of PE-X/Steel/PE-X pressure pipe:

1.5-layer structure, corrosion resistance, high pressure bearing, oxygen barrier, good mechanical strength;

2. Low corrosion cost comparing with steel pipe of the same pressure degree;

3. Low expansion coefficient, creep resistance;

4. Flexibility;

5. Light weight;

6. Applied widely in water, gas and oil transportation.

Production line performance and characteristics:

1.5-layers composition technology on originally continuous forming and welding for thin wall steel pipe, synchronous co-extrusion of inner and outer plastics;
