As a leading metrology and inspection company, OMS developed the HiLo tool, a sophisticated device that measures the misalignment between two pipes aligned for welding, nearly 20 years ago. Since then we have sold thousands of units to leading EPC contractors such as Saipem, McDermott, Subsea 7 and Technip. Commonly seen as the industry-standard tool, OMS HiLo tools have been deployed on many major global oil and gas projects, both onshore and offshore.

Reducing HiLo is an important part of confirming best fit-up selections for critical pipeline sections and of ensuring welds will pass QA/QC inspection. Accurate to 0.05mm and easily portable, OMS tools are the most accurate way to measure the misalignment between two pipes lined up for welding. Available in two varieties, the Open Gap and Closed Gap, our HiLo tools are accurate to 0.05mm and easily portable.
