2.6m Diameter Bellows Units
Overview of Case Study
We manufactured ten sets of 2.6m diameter bellows, where each set comprised of two double pivot (gimbal) type and one single pivot type, for a power station in South Wales.
Further Details Of Project
Pickup Bellows Ltd supplied the thin (three laminations of 1mm thick) stainless steel membranes, which we welded into our 10mm thick mild steel cylinders. Also there were inner and outer protection sleeves and flanges.
Because the membrane was so fragile, we also supplied a series of bracket pairs, between which we bolted short beams to act as sprags during transportation and installation.
This contract entailed coded welding, x-ray and radiography testing, dye penetrant inspection and an interzinc, intercure and interthane surface finish.
Great care was necessary when assembling the fragile membranes with 2000Kg gimbal frames.
See the photos, the workmen stood inside the tube on the roof give a good idea of the scale.
