Plastic pipe fittings and cast iron pipe fittings are not the same technical field
Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing, convenient construction and other characteristics, it has been more and more widely used in building engineering. Mainly used for building construction of the water supply system, piping, drainage, exhaust and sewage sanitary pipe, underground drainage pipe system, storm pipe and wire installation supporting the use of threading pipe.
The most widely used plastic pipe is plastic pipe. There are many kinds of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. It belongs to thermoplastic, including PVC pipe, polyethylene pipe, polypropylene pipe, POM pipe, etc. it belongs to thermosetting phenolic plastic pipe. The main advantages of plastic pipes are good corrosion resistance, light quality, convenient molding and easy processing. The disadvantages are low strength and poor heat resistance.
Plastic fittings are of national standard.Plastic pipes are usually made of synthetic resins, that is, polyester as raw materials, adding stabilizers, lubricants, plasticizers, etc., to "plastic" method in the pipe mill by extrusion processing.
