Bending pipe processing is a relatively complex task, both in terms of processing methods and processes. If not handled properly, various problems may arise, resulting in a decrease in the quality of bending pipe processing. In the face of this, the Xuzhou bending pipe processing editor will talk about a few reasons for the low quality of bending pipe processing. Friends in need can learn more about it.
1. In pure bending of bent pipes, the outer arm wall of the intermediate layer of the pipe is subjected to tensile stress and 1 under the action of external force, while the inner side is subjected to compressive stress. The combined force of N1 and N2 causes a change in the cross-section of the pipe, resulting in thickening. Based on this factor, the main reasons for the decrease in the quality of bent pipes are RX and SX. Therefore, GBJ235-82 has made clear provisions for the RX values and the thinning amount on the outside under various pressure levels, in order to control the values of RX and SX and ensure quality.
2. The accuracy of bent tubes is also one of the important factors affecting the quality of bent tubes. In the manufacturing of bent tubes, in addition to the requirement of controlling the specifications and dimensions within a certain tolerance range, users are also required to choose the corresponding bent tube according to the diameter of the bent tube during use.
3. Lubrication during the forming process can also have an impact on product quality, and improper lubrication can also reduce the quality of bent pipes. In traditional pipe bending processes, many methods are adopted to improve the surface quality of the pipe, such as using more advanced pipe bending machines, using higher strength molds, or using lubricating products. By using pipe bending machines and high-strength molds, enterprises often need to invest a significant amount of funds to complete the task.
Only by using pipe bending lubrication products can they achieve the quality requirements of the enterprise's products at a relatively low cost and quickly. However, in traditional production processes, oil-based bend pipe lubrication products can meet the quality requirements of enterprises in bend pipe production. However, the difficulty in cleaning and environmental pollution of oil-based bend pipe lubrication products are particularly prominent. Therefore, enterprises adopt more methods to eliminate the impact of using oil-based bend pipe lubrication products on product quality, and invest more energy and funds in this regard. The arrival of IRMCO water-based lubricant for bend pipes not only meets the quality requirements of enterprises for bend pipe products, but also avoids and reduces the increased investment caused by the use of oil-based bend pipe lubricant products, completely optimizing the production process of enterprises.
It can be said that there are many factors that affect the quality of bending pipe processing, including many links. In order to ensure quality, everyone must strictly control each layer of links.
