Designed for use in extreme temperature and pressure environments
SRH high-pressure plugs are designed for use in extreme temperature and pressure environments. The top no-go plug is designed such that pressure from above and below is held by key/nipple engagement. Special non-elastomer V-packing stacks are gas-tight qualified up to 25,000 psi at 450°F.
SRH plugs are available in pump-through and positive type. The pump-through type incorporates a poppet that has a metal-to-metal seal backed up by an HP/HT non-elastomer V-packing stack. A metal-to-metal knockout plug is provided for equalization. A test prong can be run to convert the pump-through plug into a positive plug for testing from above. The two-trip prong-type plug is a positive plug with no pump-through feature. The packing on the prong uses the same type of HP/HT V-packing stacks as used on the plug body. The prong is pressure balanced for easy removal under high-pressure differential to allow for equalizing before retrieving the plug.
