The advantages and applications of PE pipes
The chemical name of PE is polyethylene, which is simply understood as plastic. The plastic bags and plastic wrap used in our daily lives are PE. Of course, this is only the most basic explanation, because PE materials have high strength, high temperature resistance, corrosion resistance, non-toxic, wear and other characteristics.
PE polyethylene pipe is divided into many types, which can be divided into water supply pipe, gas pipe, mining pipe, sewage pipe, and non-excavation cross pipe threading pipe. According to raw materials can be divided into HDPE, LDPE, LLDPE. The following focuses on the different uses of PE pipe.
The PE water supply pipe is a replacement product of traditional steel pipe and polyvinyl chloride drinking water pipe. The pipe has a smooth inner wall, low frictional resistance, good low-temperature resistance, corrosion resistance, safety and health, good flexibility and other excellent features; in addition, the product is light in weight, easy to install, handle, connect, convenient and reliable construction, long service life more than 50 years. It is mainly used in the temperature of not more than 40 degree, general water transport, and drinking water transportation, mainly used in municipal buried water supply, construction water supply, farmland irrigation, residential quarters, plant buried water supply systems.
The PE mining pipes must withstand certain pressure. HDPE resin with high molecular weight and good mechanical properties is usually used. Its wear resistance exceeds many metal materials (carbon steel, stainless steel, bronze, etc.) under strong corrosion and high wear conditions. The service life is 4-6 times that of steel pipes, and it can be used for 50 years under safe use, with significant economic benefits. It is suitable for places with underground water supply, air discharge, air pressure, shotcreting and gas discharge where underground temperature does not exceed 40 degrees.
PE gas pipes, like mining pipes, must also withstand certain pressures during use. HDPE resin meets the gas pipe standards. We all know that, as a gas pipeline, for safety reasons, must have a series of advantages: stable and reliable interface, material impact resistance, and resistance. Cracking, aging, corrosion resistance and so on. Compared with traditional pipes, HDPE pipe systems have the above advantages and have a long service life of up to 50 years. Suitable for gas pipelines with working temperature between -20-40 degrees and long-term maximum working pressure not exceeding 0.7MPa.
Sewage PE pipes, also known as high-density polyethylene pipe, English: HDPE. Because of its advantages of wear resistance, acid and corrosion resistance, high temperature resistance, and high pressure resistance, it has gradually replaced the traditional pipes and cement pipes in the market, especially because it is lightweight and easy to install and move. It is the first choice a in all new material.
PE pipe is often used as the pipe of choice for municipal engineering, mainly used in: urban water supply, sewage treatment industry.
Because the PE pipe has good resistance to insulation and its own strong pressure resistance, it can also be used as a power threading pipes. In addition, PE pipe applications also include PE biogas pipes, PE-RT heating pipes for hot and cold water, PE telecommunications, cable sheathing pipes, etc. Its wide range of uses is unmatched by other materials, and it is believed that in the future development , PE pipe will have more innovation.
