Severn Trent Water awards Radius long-term contract

set up, but also had to be vibration free, so we could achieve those very tight specified tolerances,” explained Mr Wagnitz. “This rig could be fixed with completely free movement, thanks to the magnetic clamping system, so the single slot could be fixed horizontally or vertically to cut either hole or slot. Once the power was applied it virtually became part of the coker unit. And we designed it so the frame was only 70mm from the work surface. That meant vibration was kept to an absolute minimum.” OMVmanagers were said to be delighted with the result. “It was excellent research and development that produced the right tool specifically for this specific project,” said Mr Wagnitz. “The work was completed in good time with the accuracy demanded and in the time allowed, and the coker units now operate just as the client wanted.” diameters from 25 to 180mm. Innovative Radius products and systems, such as the QuickTee single-weld electrofusion fitting, were key elements featuring in the contract award. Radius sales and marketing director Iain Knowles credited the contract win to high levels of delivery and performance: “We have proven our ability to deliver on an ongoing basis over a number of years, but more importantly our relationship with Severn Trent has provided them with a combination of short-term advantages and longer-term benefits.

Hydratight has used its machining expertise to aid managers at the OMV refinery at Burghausen in the Bavarian ‘Chemical Triangle’. When optimising processes, OMV engineers wanted to improve tension on the base of two huge coker units. This required the precise change of geometry on different borings and slots, and this had to be performed 196 times. “Geometry change of borings or slots isn’t normally a big task, even though the admissible tolerance here was very tight,” explained Hydratight’s project engineer, Goetz Wagnitz. “The challenging part of the job was to achieve the same accuracy for all the slots, so the coker units wouldn’t suffer out-of-specification stresses.” The entire project had to be completed during a scheduled 30-day shutdown – a rate of almost 11 completed slots per day, with two teams of Hydratight specialists working in shifts around the clock. To achieve the required accuracy the team developed a special milling frame, which allowed not only precise worm-gear driven control of the cutting head, but also fast set-up and transfer from slot to slot. After testing several approaches at their workshop in Dietzenbach, on the outskirts of Frankfurt, the team came up with a super-stiff steel rig that could clamp to each coker unit with 18 super- powerful electro-magnets. “We needed something that offered not only fast Radius Systems has been supplying Severn Trent Water with PE pipes for more than 10 years, and has recently been awarded a new contract from the company, for the supply of PE pipes plus electrofusion fittings. The contract is for an initial three-year period, followed by options to renew for two further two-year periods. Radius Systems will supply potable PE blue and non-potable black pipes from 25 to 630mm in diameter, along with Puriton, Radius Systems’ specialist barrier pipe for use in contaminated land, in
