I. Introduction of Ginde Polyethylene Gas Pipe
Properties of Ginde Polyethylene Gas Pipe:
1). Long lifespan: PE gas pipe can be used for fifty years at least on rating temperature and compression;
2). Good corrosion resistance: it is in condition to corrosion of many chemic mediums expect very few strong oxidants; no electrochemical corrosion;
3). Excellent antifriction property: inside wall is very lubricous, rub coefficient is very low, and ability of overpass of medium is respective improve and it has excellent antifriction property. The wearable capability is four times than steel tubing when carry sand and pulp;
4). preferable impact resistance: PE gas pipe has good toughness, its impact resistance is preferably and it will not breach when heavy things impress directly;
5). Reliable connect performance: unique electric heat melting jointing and heat melting abutting joint technical make strength of joint higher than strength of the pipe body. Sealing surface will not break out as earth moves or action of the load, so this can protect safe reliability of the joint;
6). Good construction performance: the pipe is lightweight, easy for transportation and installation, the jointing process is simple, fast construction, and synthesis cost has obviously decreased.

II. Application range of Ginde Polyethylene Gas Pipe:This product is mainly used for transportation and mounting of natural gas, liquefied petroleum gas, artificial gas, and also can be used in the area of chemical industry, medication, paper making areas and so on.
III. Production technique of Ginde Polyethylene Gas Pipe
1.Production equipment
Ginde group has tens of advanced product line of polyethylene pipe and fittings production equipment. Adopting computer management with advanced level internationally from product exploitation to production can guarantee that the company can produce high quality product.
2.Raw material
Polyethylene gas pipe takes high quality polyethylene resin as its main raw material, adding necessary anti-oxidant and anti-ultraviolet absorber auxiliaries and so on. It is one new product which is made of pilling out and adopts imported excellent PE80 or PE100 material. The gas pipe material is produced and inspected severely according to national standard GB/T 15558.1-2003 “buried polyethylene(PE) pipes system for fuel gas The part one: tubing”, the pipe fittings are produced and suspected severely according to national standard GB/T15558.2-1995 “Buried polyethylene pipe fittings for fuel gas:,
