Pipeline Inspection - Prevent HSE Issues With Reduced Frequency Electromagnetic Tests
De BISAWiki
Pipelines are used through the world, transporting a variety of hazardous and non-hazardous substances from position to position. They're a requirement needed to keep the modern globe turning, often transporting essential resources throughout vast areas in get to hold our lights on or cars working. In this write-up we'll be concerned with Key Accident Hazard (MAH) Pipelines, which much more and a lot more the HSE (Wellness and Protection Government) have been focusing on.
Issues with pipelines can be devastating to the surroundings, staff, and the bottom line. There was an illustration in 2006, with a petroleum company in Alaska, in which they were forced to shut down a 34" diameter crude transit line, owing to a leak.
Initially the consumer needed to take a look at the integrity of the line making use of a pig, but thanks to uncertainty encompassing the pressure the line may be able to take, and environmental considerations, pigging wasn't feasible.
The issue arose from a small hole, not considerably bigger than a coin, induced purely by corrosion that resulted in loss of hundreds of thousands for the firm involved, as effectively as challenging scrutiny by the general public and shareholders.
Low Frequency Electromagnetic Strategy (LFET) is a propriety method that was initially created to examine flat bottomed storage tanks. In excess of time nevertheless it is been adapted to examine convex and concave ferrous and non-ferrous tubing and piping.
LFET has a variety of programs and can be used for every little thing from boiler waterwalls to reheaters, storage tanks, pipelines, pressure vessels and heat exchangers. There are a number of various technologies that utilise the LFET approach, and they also have been adapted to match a variety of scenarios.
Defects this sort of as corrosion cells, hydrogen damage, caustic gouging pitting, standard wall loss, MIC attack, FAC, erosion, corrosion and cracking can all be detected.
It was this technologies that at some point solved the dilemma of the petroleum firm previously mentioned, the LineCat O.D (Outer diameter) pipe scanning program was designed in 21 days utilising LFET, and mobilised to speedily scan the 13 miles of pipeline that essential to be inspected. This gave a 600% increase in pipe scanning pace and developed the information that ensured it was in truth protected to pig the system.
As has been mentioned LFET is an incredibly flexible strategy and when it arrives to pipelines the LineCat is unbeatable on speed. Inspections speeds of ten-fifteen toes/moment are normal, and inspection by way of uniform scale or coatings is not a difficulty. It is also able of inspecting non-ferrous as well as ferrous piping.
HPS are a world leading integrated design and manufacturing company, specialising in the development, production, installation and commissioning of product recovery systems (formally known as pigging) for liquid process companies with focus on hygienic liquid transfer requirements in the food and drink, cosmetics and personal care, household products, and pet food processing industries. This is done by installing “pigs” into your existing or new pipeline. HPS helps businesses to increase profitability by maximising product yield, and has successfully commissioned over 1,200 systems in over 60 countries around the world.
