Tube-Upsetting-Machine Manufacturer in Bangalore. The tube upsetting process is the application of hot forge at the ends of the tubes. The upset increases the wall thickness to provide the machining stock and strength necessary for joining the tubes together. The dimensions of the upset ends for oil industry tubes differ based on the API standard. The configuration of the tube end may be classified as external upset, internal upset and internal-external upset. Depending on the type of upset, the wall of thickness may be increased by a maximum of 50% for external or internal-external upsets. It may be increased by a maximum of 100% for internal upsets. Depending on the limits, the API upsets can be forged in one or two operations.Forging of tubes generates tremendous forces across the dies. The forge area on the tube upsets is normally about 3 to 10 times greater when compared to conventional forging machines. Our tube upsetters have substantially longer headerslide stroke, stock gather and hold-on. The available die length on our upsetters is considerably longer than that on a standard forging machine’s.Our Pipe Upset Induction Heating is an ideal technology for all your pipe upsetting needs.
