water supply and drainage engineering is the most commonly used material is a variety of pipes, and you are these commonly used pipe and what do you know!

1. Polyethylene (PE) Pipe

PE pipe processing does not add heavy metal salt stabilizer, the material is non-toxic, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water. Except for a few strong oxidants, it can resist the erosion of a variety of chemical media; no electrochemical corrosion. Under rated temperature and pressure conditions, PE pipes can be safely used for more than 50 years. PE pipe has good toughness, high impact resistance, and heavy objects are directly pressed through the pipe, which will not cause the pipe to rupture. The strength of PE pipe hot melt or electric fusion interface is higher than that of pipe body, and the joint will not be disconnected due to soil movement or live load. The pipeline is light, the welding process is simple, the construction is convenient, and the comprehensive cost of the project is low.

2. random copolymer polypropylene (PP-R) water supply pipe

PP-R pipe is also called three types of polypropylene pipe, the use of random copolymer polypropylene through extrusion into pipe, injection molding into pipe fittings. It is a new type of plastic pipe product developed and applied in Europe in the early 1990 s. PP-R the end of the 1980 s, the gas phase copolymerization process was used to make about 5% PE randomly and uniformly polymerize (random copolymerization) in the molecular chain of PP and become a new generation of pipeline materials. It has good impact resistance and long-term creep performance.

PPR pipe advantages: moderate price, stable performance, heat insulation, corrosion resistance, smooth inner wall without scaling, piping system is safe and reliable, and does not penetrate, the service life can reach 50 years. It is known as never scaling, never rust, never leakage, green high-grade water supply material.

PPR pipe shortcomings: high construction technology requirements, the need to use special tools and professionals for construction, in order to ensure the safety of the system.

PPR pipe application:

1, the building's cold and hot water system, including central heating system;

2. Heating system in buildings, including floor, wall panel and radiant heating system;

3, can be directly drinking pure water water supply system;

4. Central (centralized) air conditioning system;

5, transport or discharge of chemical media and other industrial piping systems.
