Several Production Methods For Seamless Tubes

The seamless steel tube is a long strip of steel with a hollow section and no seams around it. Its characteristics are as follows First, the thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, the greater the processing cost of the seamless pipe factory; secondly, the process of the product determines its limitations.Selecting a tube end forming method - The FABRICATORFabricators that need to do end forming have many choices. Even after narrowing the process down to using a ram or segmented tooling, choices abound-the tooling can form the ID, the OD, or both; and operation can be manual or CNC. Understanding the processes and their capabilities are the keys to choosing the best one for the application.Selecting a tube end forming method - The FABRICATORAlso called bulldozing, ram forming uses an impact process to drive a tapered plug inside or a tapered cup over the outside of a securely held tube end (see Figure 1). The tapered angles convert this vertical (axial) force to radial changes in the tube end shape. The process works the full circumference of the tube end uniformly.
