dn20/25/32/40/50/63/75/90/110/125/160/180/200/225/250 large diameter PE water supply pipe
dn225 large-caliber PE water supply pipes and fittings are produced using imported PE100 or PE80 as raw materials. The specifications, dimensions and performance meet the requirements of GB/T13663-2000, GB/T13663.2-2005 standards, and the sanitary performance meets the GB/T17219 standards and national hygiene standards. Ministry-related safety evaluation regulations, PE environmental protection and health water supply pipes have the advantages of good flexibility, strong corrosion resistance, light weight, and excellent impact resistance. Pipes and fittings can be connected by hot-melt sockets, hot-melt butt joints, and electric fusion, so that the pipes and fittings are integrated, the system is safe and reliable, the construction cost is low, and it is developing rapidly in engineering applications. The vigorous promotion of PE pipe conforms to the guidelines of the Ministry of Construction and the State Economic and Trade Commission for the development of chemical building materials and meets the development needs of improving people's living standards.
■ Electric heat welding: use a special electric welding machine to connect the straight pipe to the straight pipe, and the straight pipe to the pipe fittings. Generally used for tubes below 160mm.
■ Hot-melt butt connection: use a dedicated butt welder to connect pipes, generally used for pipes above 160mm.
■ Steel-plastic connection: It can be connected by flanges, threaded screws, etc.
■ In order to facilitate construction and ensure construction quality, corresponding tools should be prepared.
Such as: Rotary cutter to cut the pipe; Rotary scraper-to scrape the oxide scale on the surface of the pipe; Wall climbing scraper-to scrape the surface of the large-diameter pipe; Air cut tool-to realize the on-site operation of the air cut.
1. Long service life: Under normal conditions, the service life can reach 50 years.
2. Good hygiene: PE pipe is non-toxic, does not contain heavy metal additives, does not scale, and does not breed bacteria, which can solve the problem of secondary pollution of drinking water. It complies with GB/T17219 safety evaluation standards and regulations of the Ministry of Health.
3, can withstand the corrosion of a variety of chemical media: no electrochemical corrosion.
4. The inner wall is smooth, the friction coefficient is extremely low, the medium's passing capacity is correspondingly improved, and it has excellent wear resistance.
5. Good flexibility, high impact resistance, strong shock and distortion resistance.
6. Light weight, convenient transportation and installation.
7. Unique electric fusion connection, hot fusion butt joint, and hot fusion socket connection technology make the interface high in strength with the pipe body, ensuring the safety and reliability of the interface.
8. The welding process is simple, the construction is convenient, and the overall project cost is low.
9. PE environmental protection and health water supply pipes dn20~dn90 are blue, dn110 and above are blue or black with blue lines, other colors need to be customized, and the color of accessories corresponds to the color of the pipe.
