Once green tubes enter our facility they are upset in accordance with customer specifications. Drill Pipe International, LLC offers an external upset (EU), internal upset (IU), and an internal-external upset (IEU). Our group 1 and 3 upsets utilize a geometry which minimizes stress concentration. Tool joint assembly is designed to improve the transition from the cross section of the pipe to the tool joint weld neck. Our internal (IU) and internal-external (IEU) upsets are designed to have a longer internal upset taper (miu) than the industry standards 5D requirements. After upsetting, QC supervisors inspect the pipe to guarantee upset dimensions and quality.
