The factors affect the ERW steel pipe quality during production

In order to ensure the quality of ERW steel pipe during the production process, we need to analysis which factors will affect the product quality. Through a deep data collecting from our

 Φ76mm high frequency welding unit for a month, we believe that the ERW steel pipe quality will be affected by raw materials, welding process, the roll adjustment, roll material, equipment failure, the production environment etc. Among these factors, the raw materials accounted for 32.44%, welding process accounted for 24.85%, the roll adjustment accounted for 22.72%. These three factors are the main factors affect the ERW steel pipe quality during the production. While the roll material, equipment failure, and the production environment are the three factors only accounted for 19.99% which is defined as the less important factors. Therefore, during the ERW steel pipe production process, we need to focus on the factors matters which are raw materials, welding technology and roll adjustment.
