Because of its good comprehensive performance, elbow is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, power, aerospace, shipbuilding and other basic projects.

It is required to control the curvature radius of the elbow. For example, if the radius length is 1.5D, the radius of curvature must be within the required tolerance range. Because most of these pipe fittings are used for welding, in order to improve the welding quality, the ends are turned into grooves, with a certain angle and a certain edge. This requirement is also strict. The thickness of the edge, the angle and the deviation range are specified, and there are many more items in geometric dimensions than the pipe fittings. The surface quality and mechanical properties of the elbow are basically the same as those of the pipe. For the convenience of welding, the material of the steel and the connected pipe shall be the same.
