In-line measurement solutions for dimensions and shape

The open gap tool is designed to measure the internal hi-lo of an open gap bevelled pipe joint. The closed gap tool is developed for use with automatically welded pipe. Both tools are part of a range of Pipe Checker devices from OMS that offer accuracy and repeatability to quality assurance in pipeline welding. The Pipe Checker closed gap hi-lo tool is used to measure the hi-lo at the bottom of the J prepped pipes. The measurement is taken in one step that is both accurate and repeatable, avoiding any human errors. The use of standard digital gauges means that the tool is simple to use and familiar to inspectors. Optical Metrology Services Ltd – UK info@omsmeasure.com www.omsmeasure.com Profilemaster systems are available in multiple designs, depending on the requirements of the customer and product. The systems are suited to the continuous measurement and monitoring of dimensions and the complete cross-section of profiles made of steel, metal, plastics or rubber. The new series of Steelmaster hot and cold gauges, based on high-speed laser scanning, offers up to 12,000 measurements per second, with new calibrated single scan (CSS) technology. This results in a highly accurate and fast non-contact measurement of diameter, ovality and width/height at production speeds of 100m/s (19,685ft/min) and beyond. Steelmaster gauges are available in static (SMS models), oscillating (SMO models) or rotating (SMR models) configurations, and for diameters of up to 500mm (20").

principle of light-section technology and machine vision, and can handle any shape or profile. Relevant dimensions entered into the program are monitored during the production run at all times. Typical applications are hot seamless pipe and profiles of any kind, cold rolled/welded tubes and pipes (ERW) and inspection stations for tube, pipe, profiles and bar.

Makers of seamless pipe, tube, profiles and bars now have access to Zumbach gauges, which have been enhanced to offer significant advantages. A new large Profilemaster ® model – SPS 800-S8 – completes the line of hot and cold in-process gauges for rounds up to diameter 600mm (23.62") or profiles of up to 550mm (21.65") edge lengths. Profilemaster gauges are based on the

Hi-lo gap measurement tools Two hand tools for measuring hi-lo gaps in steel catenary risers (SCRs) and other fatigue-sensitive pipes are now available from oil and gas pipe measurement specialist Optical Metrology Services (OMS). The tools are easy to use and are claimed to provide greater accuracy and repeatability than traditional hi-lo gap measuring methods.

Every weld is critical to the successful creation of a pipeline. When welded, SCR pipes are required to have a very small (typically less than 0.5mm) internal mismatch in geometry or hi-lo gap. In the past, a variety of inaccurate and poorly repeatable methods have been used to measure the hi-lo gap, which also normally require a two-step process. To solve these inaccuracy problems, OMS has designed and manufactured two new hand tools – the Pipe Checker ‘open gap’ hi-lo tool and the Pipe Checker ‘closed gap’ hi-lo tool. These tools are accurate, repeatable and fast to use, with a digital gauge to measure the hi-lo mismatch in a single operation.
