The main use and material division of butt welding elbow

Butt-welding elbows are mainly used to connect two sections of pipes with different end-face radii, or for pipe resizing.This type of elbow generally needs to be produced according to specific engineering requirements or drawings. In addition to meeting the requirements of pipe diameter, it must also consider the specific situation of the pipeline, such as pipeline conveying pressure, fluid viscosity, abrasion, corrosion, fluid conveying temperature and other factors.Usually the welding elbow is welded in the pipeline construction, which is due to the different welding standards of all kinds of pipelines, and it needs to be welded on site according to the weld level of the pipeline.After welding elbow 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, in order to avoid corrosion or corrosion of the elbow at the welding seam, which causes too short service life of the elbow.
