Astm A234Wpb 90° Sch40 Elbow Buttweld Pipe Fitting Wholesaler Price

The production process of butt welding elbow is: use an iron plate to heat it to the heating point, and then send it to the press mold. Generally, it can be pressed three times, and then the blank is placed on the cutting disc, and the excess part is removed. Cut it off, then let the AB surfaces combine, butt, and then connect by electric welding, and then flatten the elbow mouth with a lathe, which is generally made in this way. After the welding construction operation is completed, it is necessary to carry out anti-rust or anti-corrosion treatment according to the actual situation or the external environment of the pipeline to prevent the elbow from rusting or corroding at the weld. Butt welding elbows are usually welded at the pipeline construction site. , This is because the welding standards of various types of pipelines are different, and it is necessary to carry out on-site welding according to the level of pipeline welds. Butt welding elbows are mainly used to connect two sections of pipelines with different end face radii, or to change the diameter of pipelines. Like this type in In the case of general needs, production should be carried out according to specific engineering requirements or specific drawings. In the production process, in addition to meeting the requirements of the diameter of the pipeline, the specific conditions of the pipeline must also be considered, such as the pressure of pipeline transportation, fluid Factors such as viscosity, wear, corrosiveness, and fluid delivery temperature must be considered.
