A robust and compact 4-bolt fitting, the BlueSky BlueLock clamp connector is engineered as a high performance alternative to flanges.
The BlueSky BlueLock clamp connector is a reliable, easy-to-assemble, metal-to-metal sealed connector designed for use in piping systems requiring high integrity seals in applications involving corrosive, erosive, high temperature, high pressure, and cyclic conditions. It is engineered for pressure vessel nozzles and closures, process piping, compressors, pumps, manifolds, and valves.
The clamp joint has the following configuration:
2 clamps, 2 hubs, 1 seal ring, 4 studs and 8 nuts
The seal ring is a zero leakage, reusable, metal-to-metal gasket interfaced with the hub sealing surface to ensure high integrity and a reliable seal. The joint configuration ensures that the seal ring is elastically loaded during assembly to offer a self energized seal during operation.
Freudenberg Oil & gas Technologies will custom design and optimize specialty BlueLock products to suit any application.
Just 4 bolts to install, compared with 8-24 bolts for conventional flanges. The BlueLock connector is still effective even when the tightening of bolts is uneven.
The efficient design results in a BlueLock connector that is substantially smaller in size and much lighter in weight when compared to an equivalent ANSI or API flange class.
Lower torque requirements, no requirement for special hydraulic tensioning.
Quick assembly/disassembly with fewer bolts –and parts- overall, no bolt holes to align.
Lower “total installed cost” – particularly in 900# class and higher services.
The pressure assisted seal tolerates changes in temperature and load for zero fugitive emissions in situations that might cause conventional flanges to leak.
The BlueLock connector sealrings can continue to be used in service, whereas conventional RTJ rings are crushed and not considered reusable.
The heart of Bluelock's success is the pressure energized seal. BlueSky Bluelock ® clamp connectors do not rely on the conventional flange gaskets and correctly tensioned bolts to maintain the integrity of the seal.
The four basic elements of the BlueSky Bluelock ® clamp connector are hubs, sealring, clamps and bolting. When bolting the assembly, the hubs are drawn together by the twin wedge action of the two clamp segments compressing on the sealring to make the first-stage self-energizing seal.
