The stamping and welding elbow is made of sheet material with the same material as the pipe material, and the stamping die is stamped into a half circular elbow. Then the two half ring elbow is assembled and welded. Due to the different welding standards of all kinds of pipelines, the spot welding and semi finished products are usually released according to the group. The on-site construction is welded according to the welding seam grade of the pipeline, so it is also called two welded elbow.
purpose
A pipe fitting used in the installation of pipes is used to connect two pipes with the same or different diameters to make the pipe turn at a certain angle.
Advantage
The stamping process has high production efficiency, convenient operation, easy to realize mechanization and automation, this is because the stamping dies and stamping equipment rely on to complete the processing, ordinary press trips per minute

90 degree butt welding elbow
Up to dozens of times, high speed pressure can reach hundreds or even more than a thousand times per minute, and each stamping stroke may get a stamping part.
The stamping generally without cutting scrap generated, material consumption is less, and no other heating equipment, which is a kind of material saving, energy saving and processing, lower the cost of stamping parts.
The stamping processing size range is large, complex shape parts, such as a small clock stopwatch, large car rails, covering parts, stamping and material hardening effect of cold deformation, punching strength and stiffness were higher.
And when the stamping die to ensure the dimension and shape precision stamping parts, and generally do not damage the surface quality of stamping, and die life is generally longer, so the stamping quality, good interchangeability, "as like as two peas" feature.
The forming process of the stamping elbow is complicated. It needs to be welded on the basis of different materials and uses, and it is gradually formed under certain pressure. The forming of stamping elbow should be carried out according to a certain process and strictly follow the corresponding process. Otherwise, the quality problem will be produced if the stamping elbow is produced. According to the needs of a circular ring shell can be cut into 4 or 90 degree elbow elbow 6 60 degree elbow or other specifications, the process is suitable for manufacturing elbow in diameter and the bend diameter ratio is larger than 1.5D of any large size push bend, is the ideal method for manufacturing large push bend.
