TapAble Flange

TapAble FlangeThe Oil States TapAble Flange is a cost-effective, pressure- containing alternative to a subsea valve tie-in. The flange reduces the cost of fabrication time associated with a typical subsea valve assembly. When ready for the lateral tie-in, a hot-tap machine is installed to tap out the flange blank.

The flange is machined from a single, A694 forging, which eliminates welding issues and possible project-specific C.E. requirements associated with cast flanges.
