Cryogenic swivel joints emerge as pivotal solutions within hose and articulated pipework assemblies, serving the essential purpose of enabling rotational movement along the line. This functionality holds dual significance, as it not only relieves stress and torsion on hoses but also facilitates the achievement of required angles and orientations for fluid transfer processes.
In the realm of cryogenics, the role of swivel joints becomes even more critical. Cryogenic substances pose significant risks due to their extreme cold temperatures and potential harm to operators or the environment in case of accidents. Maintaining the integrity of the line is paramount to avoid stresses and torsion that could lead to fractures in hoses or pipework, ensuring both operational safety and environmental protection.
EWFM acknowledges the gravity of cryogenic applications and has devised specialised solutions to address these challenges. Both our standard and engineered swivel joint ranges can be adapted to suit cryogenic environments. Notably, our design includes a small 1/2″ port integrated into the ball race of the swivel, allowing for nitrogen purging. This strategic addition prevents freezing, ensuring the cryogenic swivel joints remain functional, smoothly rotating even under the extreme conditions presented by cryogenic fluids
