MCA Hire and Thermofuse Pipelines in repair programme

treatment works in Oswestry to the Prescot Water treatment works near Liverpool. LTDM number 3 is bitumen- lined steel that will be pressure jetted. Lines 1 and 2 of the LTDM are unlined cast iron and will be refurbished with polyethylene (PE) using the specialist technique of swage lining, a process applied by Denholm Pipecare. The swage lining technique is where butt welded strings of a liner are drawn through a specialist reducing die to reduce the overall diameter of the PE lining and allow insertion into the host cast iron main. Over a period of time the PE’s elasticity will allow the PE lining to revert to its original diameter, creating a tight fit and maximising the bore of the newly lined cast iron main. The specialist operation of butt fusion welding of the large diameter liner is being carried out by Thermofuse Pipelines. MCA, part of Drain Center, was involved with the Vyrnwy project when trials first started four years ago. It provided a McElroy 1648 specialist large diameter butt fusion machine, and as the project developed, MCA imported an additional brand new McElroy 1648 welding

The team will be working to repair three existing LTDM’s that run from the water

machine from America to enhance on-the-job performance, which is due to make its first UK site appearance next week. Efficiency on-site is already high. United Utilities set the team a target of eight welds per day, but the team from Thermofuse Pipelines sometimes find themselves completing ten or 11 welds in a day. The maintenance and repair work on the pipelines is part of United Utilities’ 14-year cleaning and maintenance programme to the Vyrnwy LDTM to improve water quality. The Vyrnwy LDTM consists of three parallel pipelines with a total length of around 240km.
