Butt weld elbows use resistance heating to simultaneously weld two workpieces together along the entire end face. Field installation usually adopts two methods of resistance butt welding and flash butt welding. Butt weld elbow is a kind of elbow formed by hot pressing of steel or by forging technology. The connection method is the butt welding of the elbow pipe and the steel pipe. High productivity and easy automation, so it has been widely used. The following is a detailed introduction to the characteristics of butt weld elbows in construction.

Feature 1: Butt weld elbows are mainly used to connect two sections of pipes with different radii at both ends, or to change the diameter of pipes. Such elbows usually require compliance with specific requirements or specific drawings, in addition to compliance with pipe diameter requirements, conditions in the pipe such as pipe pressure, fluid viscosity, abrasives, corrosive fluid transport and many other factors such as temperature should also be considered.
Feature 2: The butt weld elbow has a weld seam, and the elbow is rusted or corroded after the welding operation or after the external environment of the pipeline to prevent corrosion and avoid bending or rusting during the welding process.
Feature 3: Usually, when welding butt weld elbows at the pipeline construction site, due to the different welding standards of various pipelines, it is necessary to carry out on-site welding according to the welding level of the pipelines, which is another feature of butt weld elbows.
