Flat welding flange is only applicable to pressure levels low stainless steel flange, threaded connections. The fatigue life of flat welding flange is only about a third of the butt welding flange, subjected to internal pressure and the performance of flat welding flange, stainless steel flat welding flange though the price is cheaper than stainless steel threaded flange. Easy to damage the flange surface and cause the deformation of the flange surface, cannot be used in under the action of alternating stress, stainless steel threaded flange is used in the occasion of galvanized steel pipe and cast iron flanges can't welding.
