304 stainless steel butt welding elbow not only saves space and weight, but more importantly, it ensures that the joint will not leak and has good sealing performance. Due to the reduction of the diameter of the seal, the size of the compact flange is reduced, which will reduce the cross-section of the sealing surface. Secondly, the flange gasket has been replaced by the sealing ring to ensure that the sealing surface matches the sealing surface, which mainly brings convenience to the pipeline designer.
Butt welding elbow is an elbow formed by steel hot pressing or forging technology. The connection method is butt welding with the steel pipe through the elbow. Using resistance heat to weld two workpieces along the whole end face at the same time, there are usually two methods: resistance butt welding and flash butt welding. They have high productivity and are easy to realize automation, so they have been widely used.
Feature 1:Butt welding elbows are mainly used to connect two pipes with different end radius, or to change the pipe diameter. Usually, such elbows need to be produced according to specific engineering requirements or specific drawings. In addition to meeting the requirements of pipeline diameter, the specific conditions of the pipeline must also be considered, such as pipeline transmission pressure, fluid viscosity, abrasiveness, corrosivity, fluid transmission and many other factors. It has certain pertinence and applicability, which is another important construction and use feature of butt welded elbow.
Feature 2: the butt welding elbow has welds. After the welding operation is completed, the butt welding elbow needs to be treated with anti rust or anti-corrosion treatment according to the actual situation or the external environment of the pipeline to avoid rust or corrosion of the welds. This process can ask us to clarify the quality of butt welded elbows before use.
