Piggable Ball Swivel Flange Assembly Suppliers

Destec supplies piggable ball swivel flange assemblies as part of the Desalign Misalignment Ball Flange range, built so that pipeline pigs can pass through the connection in either direction for inspection, cleaning or product batching purposes without the swivel function interrupting the pig's path. The assembly is available in both 1500lb and 900lb ANSI rated versions, with a defined size table covering nominal pipe sizes from 4 inch to 24 inch, matching each Desflex flange size to its corresponding ball seal size and complete ball swivel assembly reference. Sealing at the bore uses Destec's own technology rather than a conventional flange gasket, keeping the internal bore profile smooth enough for reliable pig passage. This combination of piggability and misalignment tolerance suits pipeline operators who need both a smooth internal bore for pigging operations and a joint capable of accommodating some degree of angular misalignment along the route.
