The performance characteristics of stainless steel elbow

Stainless steel elbow is a kind of elbow formed by steel hot pressing or forging technology. The connection method is through the butt welding of the elbow and the steel pipe, and the two workpieces are welded together along the entire end surface using resistance heat. Usually there is a resistance pair. Two methods, welding and flash butt welding, have high productivity and easy automation, so they have been widely used. The stainless steel elbow not only saves space and reduces the weight, but more importantly, it ensures that the joints will not leak and have good sealing performance. The size of the compact flange is reduced because the diameter of the seal is reduced, which will reduce the cross-section of the sealing surface. Second, the flange gasket has been replaced by a sealing ring to ensure that the sealing surface matches the sealing surface. The B value of a 45-degree elbow is a structural scale, which is mainly to bring convenience to pipeline planners. Stainless steel elbows have certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. Usually used for power station, chemical, petroleum and other equipment data. The weldability of stainless steel stamping elbows is poor, and attention should be paid to the welding process, heat treatment prerequisites and the selection of suitable welding rods.
