Butt-welding elbow is steel hot pressing or forging forming elbow, its connection form is directly the elbow and steel pipe butt welding, so as to change the Angle and direction of the two pipes.
Butt weld bend USES: butt welding elbow is mainly used to connect two different end radius of pipe, or used in pipe, the diameter of this type of elbow typically need according to the specific project requirements or detailed drawings for production, in addition to accord with the requirement of pipe size, must also consider the pipe concrete conditions, such as pipeline pressure, fluid viscosity, abrasion resistance, corrosion resistance, fluid conveying a variety of factors such as temperature.Urban butt-welding elbows are welded at the pipeline construction site, which is due to the different welding standards of all kinds of pipelines, and on-site welding is required according to the weld level of the pipeline.
Butt welding elbow introduction: Butt welding elbow is steel hot pressing or forging forming elbow, its connection form is directly the elbow and steel pipe butt welding, the main manufacturing standard of butt welding elbow is generally GB/T12459, GB/T13401, ASMEB16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752-1995.
Classification of butt welding elbows:
The butt welding elbow is divided into 45° butt welding elbow, 90° butt welding elbow and 180° butt welding elbow according to the Angle of the elbow. Other special Angle elbows can be customized according to the customer's drawing.Common materials of butt-welded pipe fittings include carbon steel, alloy steel and stainless steel.According to its radius of curvature, the elbow can be divided into long radius butt welding elbow and short radius butt welding elbow.The radius of curvature of the long radius butt welding elbow is equal to 1.5 times the outside diameter of the pipe, i.e. R=1.5D.The radius of curvature of the butt welding elbow of the short radius is equal to the outer diameter of the pipe, i.e. R=1D.Where, D is the diameter of butt welding elbow, and R is the radius of curvature.If divided by the pressure grade, there are about 17 kinds, and the American pipe standard is the sa
