DataTime:[2016-7-5]

Threaded flange's English name: threaded flange that is connected to the equipment or pipe thread flange.
1. Chromium stainless steel flange pipe sclerosing beautiful mark after welding flange is bigger, is easy to crack. If using the same type of chromium stainless steel electrode (G202, G207) welding, must be above 300 ℃ preheat and 700 ℃ or so slow cooling after welding. If stainless steel flange welding cannot be heat treatment after welding, should choose stainless steel flange pipe fittings electrode (A107, A207).
2. Stainless steel threaded flange, in order to improve the corrosion resistance and weldability and increasing stability element Ti, Nb, Mo and so on, some good weldability is chromium stainless steel flange. Using the same type of chromium stainless steel flange welding electrode (G302, G307), should be above 200 ℃ preheat and around 800 ℃ tempering treatment after welding. If cannot undertake the weldment heat treatment, should choose stainless steel flange pipe fittings electrode (A107, A207).

3. The threaded flange pipe fittings, stainless steel flange welding rod has good corrosion resistance and oxidation resistance, widely used in chemical, chemical fertilizer, oil, medicine, machinery manufacturing.
