1. Straightness: The docking of the straight pipe section of the coiled pipe is a very important part, which requires the accuracy of the coiled pipe cutting, the consistency of the diameter, and the automatic horizontal adjustment of the roller by tools. This can be a good way to find a balance point. Many factories are not large enough. They directly lay two steel pipes on the ground and connect sections of pipes on top of the pipes. This is only a temporary method and can meet the needs of high batch standards. To level the roller tool.
2. Welding: When making this coiled pipe, the coiled pipe is beveled according to the actual situation of the company. Most of the welding is submerged arc welding. The current and voltage of the submerged arc welding machine must be adjusted smoothly. The welding wire is selected according to the size of the groove. The flux is It needs to be dried and screened before use so that good products can be welded. If the current is unstable, pores will easily appear inside, and the surface of the weld will be unsightly like a candied haws. If the flux is not dried and screened, the welded steel pipe will have many pores.
3. Roundness: The control of roundness is at the weld. Since the material and strength of the heated weld will change, if it is not bent properly at the beginning, the pipe will be directly unqualified. It will not be bent after the welding is completed. Well finished. Weld bending is a very critical part. It would cost about 100 yuan to ask a press to bend it specially. So it is crucial to find a large press.
