PE (Polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, high temperature resistance, corrosion resistance, and non-toxicity. Because it does not rust, it is an ideal substitute for ordinary iron water supply pipes. The 110PE drain pipe complies with the national standard for products: GB/T 13663-2000 "Polyethylene (PE) Pipes for Water Supply".

Plastic pipeline development in China is progressing rapidly, with quality continuously improving. Among them, polyethylene PE pipes are widely used in building water supply, building drainage, underground drainage pipes, building heating, gas transmission pipes, electrical and telecommunications protective conduits, industrial pipes, and agricultural pipes due to their unique advantages. They are primarily applied in urban water supply, urban gas supply, and farmland irrigation.

As of today, the connection technology for polyethylene has become very mature and reliable. Statistics show that the leakage rate of polyethylene pipes is less than 0.0002, far lower than the 2-3% of ductile iron pipes, significantly enhancing the safety and economic benefits of pipelines, which is also a very important reason for the extensive use of polyethylene pipes in gas pipelines.

（1）Polyethylene has excellent corrosion resistance, good sanitary performance, and a long service life

The 110PE drain pipe is made from inert materials and can resist the erosion of various chemicals except for a small amount of strong oxidizers, and it is not prone to bacterial growth. The reason why plastic pipes have replaced steel pipes and cast iron pipes is not only because plastic pipes have lower water transport energy consumption, lower living energy consumption, lighter weight, smaller water flow resistance, easy and quick installation, lower cost, long service life, and thermal insulation functions, but also because plastic pipes have superior corrosion resistance and are less likely to breed microorganisms compared to steel and cast iron pipes.

（2）Polyethylene has uniqueflexibility and excellent scratch resistance

The unique flexibility of the 110PE drain pipe also allows it to effectively resist underground movement and end loads. In terms of strength and rigidity, plastic underground pipes are not as good as cement pipes and metallic pipes. However, in practical applications, plastic underground pipes belong to "flexible pipes" and can share the load with surrounding soil under proper design and construction. Therefore, plastic underground pipes do not need to achieve the same strength and rigidity as "rigid pipes" to meet the mechanical performance requirements for underground use.

（3）Polyethylene has outstanding low-temperature performance

The low-temperature embrittlement point of the 110PE drain pipe is -70℃, which is better than other pipes. During winter outdoor construction, polyvinyl chloride (PVC-U) pipes are prone to brittle fracture. An experience summarized from pilot projects laying PVC-U underground water supply pipes in Beijing, China, is that it is not suitable to carry out PVC-U pipe installation when the temperature is below zero degrees. Another notable evidence is that to improve the toughness and low-temperature impact performance of PP, ethylene can be copolymerized with propylene monomer to produce random copolymer polypropylene (PP-R), which generally uses the IPP process route and method to copolymerize the mixed gas of propylene and ethylene, resulting in a copolymer with randomly distributed propylene and ethylene segments in the main chain (i.e., PP-R pipe material). The ethylene content in PP-R pipe material is mostly about 3%. However, the improved low-temperature performance of PP-R is still not satisfactory, with an embrittlement point of about -15℃, which is much higher than the embrittlement point temperature of polyethylene pipes at -70℃.

The standard specifies the product specifications, technical requirements, testing methods, inspection rules, marking, packaging, transportation, and storage for polyethylene pipes (hereinafter referred to as 'pipes') made from polyethylene resin as the main raw material and extruded. This standard also stipulates the basic performance requirements for raw materials, including classification systems.

This standard applies to water supply pipes made from PE63, PE80, and PE100 materials. The nominal pressure of the pipes is 0.32MPa to 1.6MPa, and the nominal outer diameter ranges from 16 mm to 1000 mm.

The pipes specified in this standard are suitable for pressure water supply at temperatures not exceeding 40°C and general-purpose applications, as well as for the transportation of drinking water.
