Usage Of PE Pipe

1. PE mining pipe
Among all engineering plastics, HDPE has the highest wear resistance and is the most noticeable. The higher the molecular weight, the more wear-resistant the material is, even exceeding many metal materials (such as carbon steel, stainless steel, bronze, etc.). Under the conditions of strong corrosion and high wear, the service life is 4-6 times that of steel pipe and 9 times that of ordinary polyethylene; And the conveying efficiency is improved by 20%. The flame retardant and antistatic properties are good and meet the standard requirements. The downhole service life is over 20 years, with remarkable economic benefits, impact resistance, wear resistance and double resistance.

2. PE sewage pipe
PE pipe for sewage disposal is also called high density polyethylene pipe, which means HDPE in English. This kind of pipe is often used as the first choice for municipal engineering, mainly used in sewage treatment industry. Because of its wear resistance, acid resistance, corrosion resistance, high temperature resistance, high pressure resistance and other characteristics, it gradually replaced the position of traditional pipes such as steel pipes and cement pipes in the market, especially because this pipe is light in weight and convenient to install and move, and is the first choice of new materials. Users should pay special attention to the following points when choosing pipes made of this material: 1. Pay special attention to the selection of raw materials for plastic pipes. There are thousands of grades of polyethylene raw materials, and there are raw materials as low as several thousand yuan per ton in the market. Products produced by this raw material cannot be constructed, otherwise, rework losses will be huge. 2. The selection of pipeline manufacturers shall be subject to the formal and professional manufacturers. 3. When choosing to buy PE pipes, inspect the manufacturers on the spot to see if they have production capacity.

3. PE water supply pipe
PE pipes for water supply are the replacement products of traditional steel pipes and PVC drinking water pipes.
The water supply pipe must bear certain pressure, and PE resin with high molecular weight and good mechanical properties, such as HDPE resin, is usually selected. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding and difficult connection, so it is not suitable as the material of water supply pressure pipe. However, due to its high hygienic index, PE, especially HDPE resin, has become a common material for producing drinking water pipes. HDPE resin has low melt viscosity, good fluidity and easy processing, so its melt index has a wide range of choices, usually the MI is between 0.3-3g/10min.
