Characteristics of butt welding elbow in construction

There is a weld seam on the butt welding elbow.After the completion of the welding operation,the welding elbow needs to be treated with anti-rust or anti-corrosion according to the actual situation or the external environment of the pipeline,so as to avoid the corrosion or corrosion of the elbow at the welding seam.This process can make us know the quality of butt welding elbow before application.

Usually the welding elbows are welded in the pipeline construction site. This is due to the different welding standards of all kinds of pipelines, which require on-site welding according to the grade of pipeline welds. It is another characteristic of butt welding elbow that field welding should be carried out according to different pipe weld grades.

Butt welded elbows are mainly used to connect two pipelines with different end radius, or for pipe diameter modification. This type of elbow generally needs to be produced according to specific engineering requirements or specific drawings. In addition to meeting the requirements of pipeline caliber, it must also consider the specific conditions of pipeline, such as pipeline pressure, fluid viscosity, abrasion, corrosiveness, fluid transport temperature and other factors. It has a certain pertinence and usability, which is another important construction characteristics of butt welding elbow.
