Specification of our PVC -U double-wall bellows

About PVC-U

PVC-U is also called UPVC, rigid polyvinyl chloride. The full name is Unplasticized Polyvinyl Chloride. Unplasticized means "unplasticized, without plasticizer". PVC-U uses PVC as the main raw material, adds necessary additives, and is produced by extrusion molding. That is to say, it is composed of amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to using additives, the method of blending and modification with other resins is also adopted, which makes it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on.

PVC-U double-wall corrugated pipe is a special pipe with smooth inner wall, corrugated outer wall and hollow inner and outer walls, which is processed and produced by polyvinyl chloride as the main raw material. The pipe has beautiful appearance, strong pressure resistance, small water resistance, and acid and alkali corrosion resistance. It is easy to install and transport, and has the obvious advantages of energy saving, material saving and water saving.

Advantages of our PVC -U double-wall bellows

① PVC-U double-wall bellows is manufactured by using the main raw material PVC. The internal wall is smooth and the external wall is bellows type. The hollow special pipe between the external and internal walls is mainly applied into the buried sewage and drainage system. The double-wall bellow is beautiful in appearance and special in structure with 2,4,8 and 16KN/㎡ of the ring stiffness

② The interface is connected with the flexible natural rubber sealed ring, which is characterized by firm connection, non-leaking capacity, convenient carring and simple construction, etc.

③ Lower comprehensive cost than the iron casting pipe and cement pipe. The serive life can reach 50 years. The double-wall bellows is the pipe applied most in plastic buried drainage and sewage discharge pipe in all countires in the world.
