  ERW steel pipe  adopts the skin effect of high-frequency current to produce high temperature and external force extrusion at both ends of the steel plate in a short time. This is a true electrodeless metal butt. Using hot-rolled coils as raw materials, the wall thickness of ERW steel pipes can be controlled to about ±0.2mm. The end of the steel pipe adopts the American APL standard or GB/T9711.1 standard. The pipe end is cut and the conveying length is fixed. In recent years, in natural gas pipeline network projects and natural gas companies, ERW steel pipes have been widely used as the main steel pipes in urban pipeline networks. At present, ERW high-frequency straight seam steel pipe accounts for 60% of the world’s steel pipe usage With the development of the economy and energy industry, long-distance oil and gas pipelines are an important way to ensure energy. In the anti-corrosion construction process of oil and gas pipelines, the surface treatment of ERW steel pipes is ...

1. In the production process of  ERW steel pipe , how to ensure that the product quality meets the requirements of technical standards and the needs of customers? An analysis of the factors that affect the product quality during the production of steel pipes. According to the statistics of non-conforming products of Φ76mm high-frequency welded steel pipe unit in a certain month, it is believed that the factors that affect the quality of steel pipe products during the production process are raw materials, welding process, roll adjustment, roll material, equipment failure, production environment, and other reasons. aspect. Raw materials accounted for 32 .44%, below will introduce the infect of material to ERW steel pipe. The influence of raw materials on the ERW steel pipes. The factors that affect the quality of raw materials are mainly the three aspects of the unstable mechanical properties of the steel strip, the surface defects of the steel strip and the large deviations in ...
