Swivel Joints

[Inchtain]

Good morning,

In general, what are the required inspection and maintenance practices for swivel joints, that is a part of a floating suction unit inside a fixed roof tank for crude oil?

And which is the best technique to dismantle it to see the balls tracks and o-rings?

Thanks a lot.

Visual check and a manual 180° rotation of the swivel joint, apart from the hydro-test of the roof drain assembly.

Dear SEN,

It is necessary to dismantle the male and female parts of the swivel joint to see the rig joints and balls. isn't it?

Thanks
