(Summary description)Process flow and other factors for welding elbows
In the production process of welded elbows, if a long-radius elbow is to be made, it is necessary to first select the specifications, propose the pipe material, and the expansion rate. Through theoretical calculation, the expansion rate is generally between 33% and 35%, and it is pushed back.
Because some elbows will be twisted after improper handling, which is not allowed. After pushing the head, the outer diameter of the front end is generally large, and it needs to be shaped by a shaping die. , two semicircular arcs, one on the top and bottom, the short-radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, that is, R=D, D in the formula is the diameter of the elbow, R is the radius of curvature, commonly used is 1.5D 's elbow.
Welded elbows are mainly used to connect two sections of pipes with different end face radii, or to change the diameter of pipes. This type of elbows generally need to be produced according to specific engineering requirements or specific drawings. In addition to meeting the requirements of pipe diameters, welded elbows The head also considers the specific conditions of the pipeline, such as pipeline transportation pressure, fluid viscosity, abrasion, corrosiveness, fluid transportation temperature and other factors.
