Director Wye & Dual Director Wye Fittings

QCS_070The Oil States QCS Director Wye and the Dual Director Wye are bi-directional, piggable Y-shaped fittings for shallow and deepwater subsea pipeline applications.

The Director Wye permits pigging and cleaning through one predetermined leg. It uses a perforated diverter sleeve to direct the path of the pig.

The diverter sleeve will accept bi-directional pigging in the main line. The perforated sleeve still permits unobstructed flow to continue through the lateral branch. The diverter is activated externally via ROV or diver assist.

The Dual Director Wye permits pigging and cleaning of both the main and lateral lines. It uses two independent diverter sleeves to direct the pig and can be activated via ROV or diver assist. The internal sleeves are perforated to permit unobstructed flow during operations.  Pigging operations may be performed in both directions.
