Sichuan develops new composite plastic pipe

The Dongtai brand steel wire mesh composite plastic pipe developed and produced by Sichuan Chentai New Material Technology Co., Ltd. in December 2003 is made of cold-rolled steel strip and hot plastic as raw materials, and the porous thin-walled steel pipe formed by hydrogen arc butt welding is enhanced. A new type of composite pressure pipe (ie, PESI pipe, also known as Perm tube) with a double-faced composite thermal plastic in the body, outer layer and inner layer, making it a solution to the problem of banned galvanized pipe, construction water supply supervisor and system pipe network. A revolutionary technological achievement.
Hole mesh steel pipe composite plastic pipe connection can be used in the form of flange connection, but also can be used to facilitate, fast, safe and reliable tube sets of electric welding connection. The electric fusion welding connection relies on the electric heating element preset in the pipeline to be heated and heated, and melts and cools the plastic of the inner wall of the sleeve and the joint portion of the outer wall of the pipe (pipe) to be integrated.
The connection strength is high, and the connecting force between pipe and pipe fittings is >200,000 kilograms, and there are no defects such as leakage. Hole mesh steel composite plastic pipe is one of the Ministry of Construction science and technology achievements promotion project. As a transmission pipeline, it can be widely used in petroleum, chemical, pharmaceutical, mining, municipal engineering and so on.
