To ensure the production quality of bend pipe processing, it is necessary to first know what factors will affect the quality of Suzhou bend pipes, such as bend pipe materials, bending accuracy, etc. Only by understanding these factors can we better ensure the quality of bend pipes. Mr. Hu from Zhijiu, a bend pipe processing manufacturer, will tell you the factors that affect the quality of bend pipe processing?

1.When a pure bent pipe is bent, under the action of an external force distance M, the outer arm wall of the property layer is subjected to tensile stress; 1. Function and thinning, internal pressure stress. Effect and thickening, combined force N1 and N2. Change the cross-section of the pipeline. Based on this factor, the main reason for the decrease in the quality of bent pipe processing is RX and SX. Therefore, GBJ has specified values and thinning amounts RX and SX to control external values and thinning amounts under various pressure levels, in order to ensure quality.

2.When processing Suzhou bend pipes, the material is stretched on the outer side, and the position of the neutral axis of the inner pressure is different from the bending method. When working in top bending (compression bending), the neutral axis is about 1/3 away from the outer wall, and when working in rotary bending (back bending), the neutral axis is 2/3 away from the outer wall. Therefore, the use of rotary bending method is beneficial for the bending of thin-walled pipelines.

3.The accuracy of bending during pipe bending is also one of the factors affecting the quality of pipe bending. In the bending and manufacturing process of pipe bending, in addition to controlling the specifications and dimensions within a certain tolerance range, users also need to choose the corresponding bending according to the bending diameter.

4.The bending performance and surface corrosion of the bent pipe itself may also affect the bending quality of Suzhou bent pipe processing. During on-site construction, operators also need to understand the material, processing performance, and surface corrosion of the bent pipe processing pipeline.
