Stainless steel elbow is divided according to its curvature radius: it can be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the pipe whose curvature radius is equal to 1.5 times, that is, R = 1.5D; the short radius elbow refers to its radius of curvature equal to the outer diameter of the pipe, which is R = 1.0D. (D is the elbow diameter and R is the radius of curvature).

Workshop:

Welding elbow production process, if making a long radius elbow, you must first select the specifications and propose the pipe material. The diameter expansion rate is calculated theoretically. Generally, the diameter expansion rate is between 33% and 35%. The general diameter expansion rate of short 219mm is 50%. After selecting the raw materials, cut the material according to the specifications of the elbow, and then consider the radius of curvature. For example, a 90° elbow can calculate how many long materials can be processed by its curvature. 90° elbow. It can be calculated by theoretical calculation, and then cut with this length as a fixed length.

Quality Assurance:

Elbow is a kind of connection fittings commonly used in plumbing installations. It is used to connect the bends of pipes to change the direction of the pipes. Other names: 90° elbow, right-angle bend, love bend, stamping elbow, pressing elbow, mechanism elbow, welding elbow, etc.

Packing & Loading:

Requirements for packaging For small pipes, such as export, wooden boxes are required, about 1 cubic meter. The number of elbows in this box can not exceed about one ton. The standard allows sets, that is, large sets of small but total weight Generally cannot exceed 1 ton. For large pieces, they must be individually packaged, like 24″, they must be individually packaged. In addition, the package mark is marked with the size, steel number, batch number, manufacturer's trademark, etc.
