In the process of carbon steel eccentric reducer and pressing, cold pressing or hot pressing is adopted according to the different materials and changing ASTM A234wpb Seamless Carbon Steel Eccentric Reducer. Usually, cold pressing is adopted as far as possible, but in the case of severe hardening caused by multiple changing diameter, hot pressing is preferred for the case of thick wall or alloy steel material. Diameter enlargement forming of billet inner diameter. Diameter enlargement technology mainly solves the problem that the carbon steel eccentric reducer is not easy to be formed by diameter reduction. Sometimes, according to the forming requirements of materials and products, the methods of diameter enlargement and diameter reduction are combined.
Hot-pressed tees have wide adaptability to materials and are suitable for materials of low carbon steel, alloy steel and stainless steel. Especially for tees with large diameter and thick pipe wall, this forming process is usually adopted. Besides using steel pipe as raw material to produce carbon steel eccentric reducer, steel sheets can also be used to stamp large and small heads of Department specifications. The die used for drawing is designed according to the dimension of inner surface of carbon steel eccentric reducer, and the steel plate after cutting is stamped and stretched by the die.
