Butt welding elbow pipe fittings has three characteristics, detailed as follows:

1. Generally, butt welding elbow pipe fittings is carried out in the pipeline construction site, because the welding specifications of various pipelines are different, and on-site welding is required according to the weld grade of pipelines.

2. Welded elbow pipe fitting has weld. After the completion of welding operation, anti-rust or anti-corrosion treatment shall be carried out on the elbow pipe fitting according to the actual situation or the pipeline external environment, so as to prevent the elbow pipe fitting from rust or corrosion at the weld. 

3. Butt welding elbow pipe fitting is mainly used for connecting two sections of pipelines with different end face radii, or for pipe resizing. The general requirements of this type of elbow pipe fittings are based on detailed engineering requirements or detailed drawings. In addition to meeting the requirements of pipeline diameter, the detailed conditions of pipeline, such as pipeline conveying pressure, fluid viscosity, abrasion, corrosion, fluid conveying temperature and other factors, should also be considered.
