Seamless steel tube factory cold drawing (rolling) : round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating)→ multi-pass cold drawing (cold rolling)→ blank tube → heat treatment → straightening → water pressure test (flaw detection)→ marking → sto

I. Material warehouse requirements
1, keep the material warehouse clean, smooth drainage place, away from harmful gas or dust. Remove weeds and debris from the site and keep the steel clean

Stainless steel pipe fittings are widely used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of the twenty key products developed in China. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural use: for piling pipes, Bridges; Pipe for wharf, road, building structure, etc.

Sealing mode: the core of the high-pressure self-tightening flange is the perfect, metal to metal new seal, that is, rely on the elastic deformation of the sealing lip of the sealing ring (T-arm) to form a seal, belongs to the hard seal; Then the combination of sleeve section, clip sleeve and seal ring formed a strong rigid body, so that the strength of the connecting part is far greater than the strength of the pipeline base material itself.
