Recently despatched to Singapore for a UK based customer, this 20” Style 20 Carbon Steel Marine Swivel Joint with ANSI 300 RF Flanges is to be installed onto a large scale fluid transfer system.

Supporting the offshore oil & gas and marine industries, these engineered products can be used on fixed platforms, jack-up rigs, drill ships and semi-submersibles. Typically flexible pipe is used to transfer the crude oil, or other media, and can be used in conjunction with hose reel systems, chutes or cantilever A-frame systems.  These systems include deployment and recovery of the flexible hose and also provide a means of storage.

Often used in harsh, even Arctic environments, the materials used in the swivel, drybreak and hose will be manufactured to reflect this.

 

This Swivel Application

Rated for a maximum working pressure of 20 Bar

This Marine Swivel Joint, as with the many supplied to the aforementioned customer, can be safely used for efficient loading or offloading, in various offshore and onshore applications. The swivel can be customised, manufactured and engineered to suit your specification and particular application.
