Current manufacturing processes for conventional side pocket mandrels (SPM) have inherent challenges related to welding and heat-treatment.
Welding and post weld heat treatment rely on extensive human intervention, requiring stringent and elaborate QA/QC processes exceeding the current standards. As such,
satisfactory repeatability of the manufacturing process is difficult to achieve.
By utilizing modern manufacturing technologies and an innovative mandrel design, PTC has managed to minimize the number of orbital welds, and enhanced the control of post weld heat treatment, robotic welding ensures the repeatability of the manufacturing process.
