Pipe blasting and coating systems SELMERSspecialises in themanufacture of plants and equipment for internal and external pipe cleaning, pipe coating and pipe handling. Established in 1966, the company has grown into a supplier of comprehensive pipe coating systems, especially of tailor made equipment for onshore and offshore pipe coating and pipe handling facilities. Selmers also has an offshore programme aimed at pipe handling/ firing line equipment for pipe lay vessels, field joint blasting and coating systems (S-lay and J-lay), PU foams, FBE and three-layer PE, as well as multi jointing facilities for pipe spoolbases with pipe rollers, line-up systems and pipe pushers.

and quality control equipment. Its range also includes self-propelled coating removal and re-lining machines for in- situ pipeline rehabilitation purposes. Equipment is offered with full project support from first design, engineering, construction and manufacturing up to installation, commissioning and after- sales services.

The company offers concrete weight and cement mortar coating equipment, rebar powder coating lines, in-situ equipment, containerised configurations

All design and engineering work is done in-house, with short communication lines and optimum interfacing for individual equipment parts. This enables Selmers to produce reliable and efficient pipe coating plants. The company’s product range comprises an extensive external multi- layer and internal lining pipe coating plant programme, with abrasive blasting equipment, ovens, chromate and acid wash units, liquid and powder epoxy equipment and in-house made extruders. Last year Selmers received the 2015 IPLOCA New Technologies Award, sponsored by BP, for its onshore automatic vacuum field joint blaster. This machine is part of the field joint blasting and coating equipment programme, used in the field for onshore pipelines.

Internal and external pipe cleaning

Detection of oblique flaws within a 30˚ range THE pipe inspection industry has long relied on MFL inspection methods to detect flaws in pipes, but over the years the limitations of MFL on detecting oblique flaws would result in missed flaws. Before a recent release of enhanced technology, EMI inspections had only allowed for detection of oblique flaws within a very narrow range. Today, this is no longer the case, thanks to new flaw detection technology. to reliably detect and repeat on signals from oblique flaws greater than 7° to 10° off axis. Additionally, by utilising hall elements Scan Systems is able to increase the number of sensors from 16 to 64 total channels of data for better data resolution. This allows for the detection of much smaller flaws than the limitations of traditional PC coils. flaws in EMI inspection and because of its unique use of hall elements and its proprietary Digi-Pro ® processing software, if the operator is set to detect at 30°, he will pick up flaws between 0° and 30°, making for a more accurate and precise pass.

With its focus on innovation and pioneering new techniques in EMI inspection, Scan Systems has always set the technology standards for the industry. As Matt Rutledge, VP/general manager of Scan Systems, explained: “We want to make EMI inspection easier, more reliable, and more precise for our customers and with our continued advancements we’re setting that standard higher than ever before.”

Not only is traditional EMI inspection unable to repeatedly detect oblique flaws, but even the more expensive UT inspection equipment can only detect oblique flaws within the specific target angle of the probes, meaning that if the operator has specifically set his equipment up to reliably find flaws in the 30° range, he will likely miss flaws at 15° (or any other angle where it has no targeted probe). Scan Systems states that it is the first to offer the ability to detect oblique

Scan Systems’ ESP upgrade to its M-Series line is claimed to be the first EMI inspection technology to use hall elements in the longitudinal sensors, which have enabled Scan Systems to detect and repeat on flaws up to 30° off axis on the OD surface and 20° off axis ID surface. This is unheard of in EMI inspections, as traditional methods produce significant signal reductions making it all but impossible
