Welding elbows are mainly used to connect two sections of pipes with different end face radii, or to modify the diameter of pipes. This type of elbow generally needs to be produced according to specific engineering requirements or drawings, in addition to meeting the requirements of pipeline diameter.
Welding elbows also takes into account the specific conditions of the pipeline, such as pipeline conveying pressure, fluid viscosity, wear resistance, corrosiveness, fluid conveying temperature, and other factors.
Targeted and practical, this is another important construction feature of butt welded elbows. To avoid rust or corrosion of the elbow at the weld seam, this process requires us to clarify the quality of the welded elbow before use.
Characteristic 3: Generally, welding elbows is carried out on the pipeline construction site. This is because the welding standards for various types of pipelines are different, and on-site welding needs to be carried out according to the welding seam grade of the pipeline.
