Non-standard size (large diameter) HDPE pipe and fittings

BAISHITONG HDPE pipe is a perfect solution for municipal engineering system and urban water supply and drainage system. HDPE pipe adopts high-quality original  PE100 raw material, with the size range of DN 800-2000mm, and the performance conforms to ISO4427 standard and other national certification standards. HDPE pipes for water supply can be manufactured with different rated pressures, mainly: sdr11-pn16 bar, sdr13.6-pn12.5 bar, sdr17-pn10 bar, sdr21-pn6 bar, sdr26-pn6 bar, etc

Nowadays, many PN16 flange adaptor and other fittings are used in the market to act as PN20 and PN25 pressure grades. As you know, the pressure of PN16 is definitely not able to reach PN20 and higher pressure. Even if it is new material, the PN16 is difficult to achieve the PN20 and PN25. Tt is absolutely impossible to replace the PN20 with the PN16 or even the PN20. Especially for water supply pipes, fire-fighting pipes or industrial pipes, the pressure level required is generally higher. In the event of joint leakage or pressure test, it is very difficult to repair due to joint problems caused by bursting or leaking. It is very dangerous to burst the pipeline system because of excessive pressure.

With the development of technology and the increasing market demands, the PN20 and PN25 pressure pipes have been easily realized. Through the improvement of machines and technologies, it is very easy for our factory to solve high pressure grade HDPE pipes. Especially in the replacement of steel pipes of the same pressure grade, as well as in the field of fire protection, water supply, etc., our factory PN20, PN25 pressure HDPE pipe production has made a major breakthrough.

At the same time, there are no manufacturers producing the same pressure grade pipe fittings. Through our continuous efforts and technological innovation, our high-pressure grade HDPE pipe fittings have solved the problems in the current industry, successfully solved the problem of replacing the steel pipe fittings with plastic pipes, and the vacancies of PN20 and PN25 pipe fittings. A major breakthrough has been made in the field of water supply and fire pipeline.

fittings can withstand stronger pressure than the injection molded pipe fittings, With this kind of processing of HDPE pipe fittings technology. The new materials are produced into solid HDPE pipes or thick-walled pipes first, the use the CNC lathe processed into precise pipe fittings according to the drawing, comply with the relevant pipe fitting production and test standard. Especially for some special-shaped pipe fittings, like long flange adaptor(Stub end), reducers, etc., It will not be limited by moulds and quantity. it is much more cost-effective than making mould for the small quantity, The most important is the quality, because it is made from one-piece, could bear more higher pressure, it is much better than ordinary injection molding fittings.

This kind of CNC lathe processing pipe fittings are suitable for water supply, gas and other pipeline system.
