Swivel Joints And Quick Unions
Swivel joints are 22R type (2 elbows and 2 hinges) and are of forged alloy steel with hardened grooves.
Hinges are sealed by means of one gasket which is mounted without pretightening. The covers that close access to hinge balls are machined in mounted conditions and therefore are not interchangeable.
The elbows are provided with quick unions, sealed by one rubber gasket which shall be replaced when its condition indicates marked wear.
The threaded joints of the swivel joints are hydrostatic tested.
