Plastic thread pipe
Execution standard: JG 3050-1998. Popularly speaking is a white hard PVC hose, anti-corrosion, anti leakage, pipe for wire wear. Now the PE bellows are used as "electrician casing", which is very quality and cheap, beautiful and convenient.
Stainless steel thread pipe
304 stainless steel or 301 stainless steel, used as wire, cable, automatic instrument signal wire and cable protection pipe, specification from 3mm
Stainless steel pipe to 150mm. The ultra small caliber stainless steel threading tube (inner diameter 3mm-25mm) is mainly used for sensing line protection of precision optical ruler and industrial sensor line protection. It has good softness, corrosion resistance, high temperature resistance, abrasion resistance and tensile strength.
Carbon steel tube
Wire and cable protection material for the production of Q235 and the tube with a tube, usually for R=6D products. R, you will be in slow camber, when threading
It's very easy to get through. When the carbon steel threading pipe is connected with the straight pipe, it uses casing to protect the interface and then connects the pipe and threading pipe by welding. The purpose is to protect the electric wire and cable inside the interface from damage caused by electric welding. The usual specification is DN20-DN150.
