The main reasons and solutions for the decrease in the quality of bent pipe processing:
1. When the bending process is purely tortuous, the outer arm wall of the intermediate layer of the pipe is subjected to tensile stress under the effect of external force distance M; 1. The effect is to reduce the thickness and compress the stress on the inner side. The effect is increased, and the combined force of N1 and N2 causes changes in the cross-section of the pipe. According to this element, the main reasons for the decrease in bend pipe quality are RX and SX. Therefore, GBJ235-82 has made understanding rules for the RX values under various pressure levels and the thinning amount on the outside. The purpose of bend pipe processing is to control the values of RX and SX and ensure quality.
2. When processing bent pipes, the data shows that the outer side is under tension and the inner side is under compression. The position of the neutral axis is different from the bending method. In the top bending (compression and bending) operation, the neutral axis is about one-third away from the outer wall, while in the rotary bending (return bending) operation, the neutral axis is about two-thirds away from the outer wall. Therefore, the use of rotary bending method is beneficial for thin-walled pipelines with twists and turns.
3. The accuracy of bending tube processing is also one of the factors affecting the quality of bending tubes. When making bent tires, in addition to controlling the standard size within a certain tolerance scale, we also request users to select the corresponding bent tire based on the bent pipe diameter during use.
4. The flexibility and external corrosion of the processed pipe material may also affect the quality of the bent pipe. During on-site construction, operators also need to understand the information, processing performance, and external surface corrosion of the processed pipeline for production discrimination.
At the same time, Mr. Zhijiuhu informed you that rust prevention is an important part of the bending process. If the rust prevention work is not done well, it will affect the use of the bending pipe in the later stage. Therefore, we need to take measures to prevent rust, and the specific content is as follows:
Firstly, we need to start with the quality of raw materials. That is to say, before carrying out the bending process, we need to ensure that the quality of the raw materials used meets the processing requirements, and also clean up all kinds of dirt on its surface. Secondly, when cleaning, we must choose a reasonable method to prevent new pollution.
Then, after the bent pipe processing part has been made, it is advisable to apply a layer of protective treatment on its surface, which can significantly improve its corrosion resistance performance. Users no longer need to worry about rusting during later use.
In summary, rust prevention has always been an important issue in the production process of bent pipe machining parts. Therefore, we must consider the above aspects and take good rust prevention care to ensure its performance.
