Production of seamless pipe
The production process commences with solid steel rounds, also known as billets, being cut to a specific length and then heated to nearly 2,300°F in a walking-beam reheat furnace. Next, the preheated rounds are transformed into a tube shell through a process known as rotary piercing, where the billets are rolled at high speeds between two barrel-shaped rolls. The resulting seamless shells are then shaped to the desired outer diameter and wall thickness using a mandrel mill, with the help of a retained mandrel. To ensure precision, the process is monitored using cutting-edge hot-wall measuring technology. The shells are reheated and further shaped in a 24-stand stretch-reducing mill, where their outside diameters are formed to meet the customer's exact specifications. The wall thickness is once again verified using a hot-wall measuring system. After being cooled and advanced on a walking-beam cooling bed, the pipes are batch cut and stored in an in-process area, where they are managed by computer-controlled gantry cranes.
Applications of Seamless Pressure Pipe
Seamless steel pipes are a suitable choice for applications involving elevated, or corrosive substances. They find utility in a wide range of scenarios, such as heat exchangers, chemical plants, power generation facilities, shipbuilding, and oil and gas sectors, as well as for applications requiring high pressure resistance.
