Basic parameters: DN15-DN50 socket welding, DN65 above for butt welding.
Stainless steel tube → blanking → bulging → punching → flat head → welding interface (or interface) → solid melt processing → washing white → grinding welding marks → fine → air pressure detection → surface inspection → labeling and certificate → package into Library.
1, the implementation and reference standards: GB / T 12771-2000 "stainless steel welded steel pipe for fluid transmission" and GB / T 12459-2005 "butt welded steel fittings."
2, the working temperature: -40 ℃ ~ 200 ℃; glenflange
3, Tensile strength: not less than 520Mpa, elongation of not less than 35%, the product measured value of 733 Mpa;
4, flattening test: flattening the pipe to the outer diameter of 1/3, no cracks or cracks;
5, pressure test: Each pipe have been 1.6 Mpa pressure test;
6, pressure test: pipe and pipe connection, at 2.5 Mpa, packing 5min conditions, no leakage at the junction;
7, drawing test: Socket TIG welded pipe connection pull force 3 times the national standard;
8, corrosion resistance: pipe fittings by salt spray test no rust.glenflange
