Seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. It is suitable for bending and flanging. The most advantage is increasing the ability of withstanding higher pressure. So it is widely used for boiler and pressure vessel, automotive area, oil well, and equipment components.

How seamless tubes are manufactured?

The process begins with solid steel rounds, or billets, being cut to a specified length and sent through a walking-beam reheat furnace, where temperatures reach nearly 2,300°F. the yellow rounds are turned into a tube shell in mere seconds in the rotary piercing mill as the preheated billets are cross-rolled between two barrel-shaped rolls at a high speed. the seamless shells enter mandrel mill, where they are rolled over a retained mandrel to provide the needed OD size and wall thickness for the next process. the process is carefully monitored using a state-of-the-art hot-wall measuring system. the shells are then reheated for final forming in a 24-stand stretch-reducing mill, where outside diameters are formed to customers’ exacting specifications. Wall thickness is again verified using a hot-wall measuring system.

after being rotated and advanced on the walking-beam cooling bed, the pipes are batch cut and transferred to an in-process storage area, where they are handled by computer-controlled gantry cranes.
