For more than 10 years Croft have been re-meshing and refurbishing filters for a customer operating within the Chemical industry.
for final product
Xiom Scotland are specialists in blast cleaning, thermal plastic spraying and coating within the offshore energy sector. They needed a new filtration solution for a ‘pigging unit’, a device that floods subsea pipelines pushing through ‘pigs’, or rubber plugs, which clean the lines and disperse any debris.
The customer’s existing 18, 50 micron filters, parts of the pigging unit, were in poor condition and needed replacing. The filters are used in testing undersea oil and gas pipelines. Xiom contacted Croft for a quality replacement that fit in their operating unit.
Two of Croft’s engineers spent 30 hours working on CAD drawings, ensuring the technical calculations were exact. Using their specialist knowledge of which materials and specifications would work best for the task at hand, they decided to replace the outer mesh of the filters with perforated plate.
The filters would be used to sift seawater in the testing and commissioning of gas and oil pipelines off the coast of Nigeria. They filter any debris from the sea water before it passes into a pump. The water is then pumped through the pipes to weight them to the seabed and also to pass through the ‘pigs’.
Not only did Croft supply a replacement filter to exact requirements for the customer operating system, the Company was also able to enhance the quality and durability of the existing filters.
Ian Meredith, Sales and Product Development at Croft, said: “This was a challenging job that involved more than 250 hours work and a multitude of CAD drawings. Our team did a fantastic job and Xiom were very pleased with the result.”
