What are the types of plastic pipes?

At present, China municipal pipe market, plastic pipe is the steady development of PE pipe, PP-R pipe, UPVC pipe has a space for one person, one of the most strong momentum of development of PE pipe and gas pipe is notable, is the two largest application market.Compared with the traditional pipe, polyethylene pipe has reliable connection, good low-temperature impact resistance, anti advantage cracking, good chemical corrosion resistance, aging resistance, good abrasion resistance, flexibility, water resistance, convenient transportation, a variety of new construction methods etc..

Polyethylene is one of the most popular plastic resins. Because of its structural characteristics, polyethylene is often unable to withstand higher temperatures, and its mechanical strength is insufficient, which limits its application in many fields. In order to improve the performance of polyethylene, many modification methods of the crosslinking of polyethylene, polyethylene molecular three-dimensional structure by covalent bonds between the formation of a network, quickly improve performance, such as polyethylene resin shaped heat denaturation, wear resistance, chemical resistance, resistance to stress cracking and a series of physical chemical properties.XLPE with its superior performance can be hot and cold water pipes, widely used in construction engineering and municipal engineering in drinking water pipeline; pipe or conventional heating system pipe floor heating system; petroleum and chemical industry pipeline conveying fluid; food industry; refrigeration system pipeline; water system of buried pipeline; gas pipeline.

Chlorinated polyvinyl chloride pipe is a new kind of water supply pipe made of chlorinated polyvinyl chloride resin. Its biggest advantage is that it is more resistant to high temperature. This pipe application in China just started in recent years, is used in cold water and waste water, chemical solution conveying pipeline, long-term use of infusion temperature up to 120 degrees Celsius, life for 40 years.

The production material of rigid PVC pipes is PVC-U mixed ingredients, and the mixture shall be mainly PVC resin, in which the additives necessary for the production of the tubes which meet the requirements of this section shall be added, and all additives shall be dispersed evenly. Mainly used for water supply (non potable water), drainage pipes, storm pipes.PVC pipe has high hardness, stiffness and allowable stress; anti aging ability is good, durable, life can reach 50 years; corrosion resistance, low price, easy adhesion, self extinguishing; Recyclable. The utility model has the advantages of convenient installation, simple and convenient, good sealing performance, no impact resistance, poor durability, high technical requirements for bonding and long curing time.

Plastic pipe is a high-tech chemical composite building material, and chemical building material is following the steel, wood, cement, the new fourth new types of building materials. Plastic pipe with water loss, energy and material saving, ecological protection, convenient completion etc., widely used in building water supply and drainage, urban drainage and gas pipe and other fields, become the main force in the new century urban network. According to the material of pipe making, the plastic pipes used for construction can be divided into PVC pipes, chlorinated polyvinyl chloride pipes, polyethylene pipes, XLPE pipes, etc..
