What Are The Reasons For The Poor Bending Accuracy Of Stainless Steel Elbows?

Stainless Steel Weld Elbow is different from carbon steel elbow mainly in material. The chemical composition it contains will keep the surface of the elbow from rusting and corroding for a long time. So do you know what are the reasons for the poor bending accuracy of stainless steel elbows?

1. The bending accuracy of stainless steel elbows is also one of the factors affecting the quality of bent pipes. When manufacturing bending tires, in addition to requiring the specification size to be controlled within the corresponding tolerance range, users are also required to select the corresponding bending tire according to the diameter of the bent pipe.

2. The bendability and surface corrosion of the stainless steel elbow itself will also affect the quality of the bent pipe. During on-site construction, operators also need to understand the material, processing performance and production judgment of the processed pipes, surface corrosion.

3. When bending, under the action of the external force distance m, the tensile stress of the outer arm wall of the neutral layer and the compressive stress on the inner side of the neutral layer are reduced, and the pipe section is changed by the combined action of the forces n1 and n2.

4. The position of the neutral axis under the action of material tension is different from the bending method. The neutral axis of 1756 is about 1/3 away from the outer wall in the top bending (compression bending) operation and about 2/3 away from the outer wall in the rotation bending (rotation bending) operation. Therefore, it is beneficial to use the rotation bending method for thin-walled tube bending.
