2.6m Diameter Bellows Units

W.A Cooke & Sons manufactured ten sets of 2.6m diameter bellows to be used as a exhaust ducts for a power station in South Wales. Each set comprised of two double pivot (gimbal) type and one single pivot type.

Pickup Bellows Ltd supplied the thin (three laminations of 1mm thick) stainless steel membranes, which were welded into 10mm thick mild steel cylinders.

Because the membrane was so fragile, W.A Cooke & Sons also supplied a series of bracket pairs, between which we bolted short beams to act as sprags during transportation and installation. There were also inner and outer protection sleeves and flanges.

This contract entailed coded welding, x-ray and radiography testing, dye penetrant inspection and an interzincintercure and interthane surface finish.
