Gas gas buried polyethylene (PE) pipe is a new type of plastic pipe product which is made by screw extrusion with high quality polyethylene mixture as raw material. The characteristics of HDPE gas pipe, such as corrosion resistance, high temperature resistance, good flexibility and flexibility, have successfully solved the problems of easy corrosion of traditional pipe and sealing defects of interface. At present, it is widely used in the transportation field of low-pressure gas pipe.
Our company obtained the "manufacturing license of pressure pipeline components" in December 2017, and the "faithful" brand gas pipe with embedded polyethylene (PE) is manufactured in strict accordance with the national standard. All pipes and pipes have been inspected by the national building materials testing center, and all the indexes have reached the national standard.
The technical requirements
Executive standard: GB15558.1 -- 2015 embedded polyethylene (PE) pipe system for gas use part 1: pipe
GB15558.2 -- 2005 embedded polyethylene (PE) pipe system for gas use part 2: pipe fittings
Colour: tube shall be black (PE80 or PE100), yellow (PE80) or orange (PE100). PE80 black pipe should be extruded together at least
Three yellow bars; At least three orange bars shall be extruded on PE100 black pipes, and the color bars shall be uniformly distributed along the circumference of the pipes.
Length: the length of the straight pipe is generally 6m, 9m, 12m, which can also be agreed by both parties.
External appearance: the inner and outer surface of the pipe should be clean and smooth, free of air bubbles, obvious scratches, dents, impurities and uneven color defects. The two ends of the pipe are cut evenly and perpendicular to the pipe axis.
Pipe material characteristics
1. Excellent corrosion resistance
With few strong oxidants, it can resist various chemical corrosion. No electrochemical corrosion, no coating required.
2. Reliable sealing performance
PE gas pipe is mainly connected by hot melt, and the interface is integrated with the pipe. The tensile strength of the interface is higher than that of the pipe itself to ensure the safety of the whole pipe.
PE gas pipeline has excellent flexibility and adaptability to uneven reduction of pipe base. PE gas pipeline is of good seismic performance.
4. Good impact resistance
PE pipes have good toughness and high impact strength, and heavy objects directly over the pipes will not cause the pipes to break.
5. Long service life
PE gas pipeline under normal working conditions, the service life can reach more than 50 years.
6. Larger conveying flow
The pipe wall is smooth, which can improve the flow rate of medium and increase the flow rate. Compared with the same metal pipe, it can convey a larger flow rate and save power consumption.
7. Remarkable economic benefits
Low cost, less investment, compared with metal pipeline, can reduce the project comprehensive investment about 1/3, can coil small diameter pipe, can further reduce the project cost.
8. Convenient construction performance
Pipe material is light, PE material of the same volume is only 1/8 of steel, easy to handle, good toughness, welding process is convenient and simple, construction speed is quick.
