Spiral tube surface treatment method:
The reason why the spiral tube is called this name is because its appearance seems to have a spiral pattern. When production, it uses low -carbon structure steel or low alloy structure steel as a material, and then from a certain angle Production, connect it in the final welding process. Next, let's talk about what methods are when dealing with the surface of the spiral tube.

First, use the method of cleaning directly, use some solvents, emulsions, etc. to clean the outside of the pipe, which can achieve the role of cleaning the surface dust, oil and other organic matter, but deeper rust, the oxidation layer cannot be cleaned.

Therefore, when you put the acoustic tube and put it in the reinforced cage, you should also pay attention to fixing it on the main band according to the prescribed size, and for the part of the steel -free cage, add three steel bars to the port of the acoustic tube to the port of the sound tube. And control the distance between these hardware, and when you deal with the second section of the steel cage, you also need to insert materials of different lengths in the specified place, sealed it, and then pass the iron wire through the pipe material. In the lifting ring, the staff needs to pay attention to the proportion in the process to avoid excess pressure on it.
