HPHT Technology Wellhead Systems

We offer a suite of HPHT wellhead technologies that can operate in high-pressure, high-temperature applications up to 30,000 psi and 450 degF.

• Our high-capacity slip hanger is tested to 3,000,000-lbf casing load when installed in the S-bowl.
• The CANH rough casing metal-to-metal seal and MTBS Hanger recessed-pocket metal-to-metal seal are qualified to API Spec 6A Annex F (30,000 psi at 450 degF).
• Our FLS extreme service API 6A slab-style gate valves, FLS-R large-bore HP API 6A slab-style gate valves, valve removal plug lubricators, and a control choke have been proven to withstand demanding HPHT service.

HPHT Wellhead Seals

• CANH seal. Dependable metal-to-metal seal for high- and low-pressure containment of fluid and gas on machined hanger necks, rough casing, and recessed bores.
• MTBS Hanger seal. Critical-service metal-to-metal design that is recessed below the hanger OD to provide protection while running through the BOP stack.
• Hanger seal. Supported on an independent load shoulder above the slips to enable replacement at full-rated casing load capacity.
• P radially energized elastomer injection seal. Energized by injecting plastic packing between the wellhead body and seal element to affect a seal in moderate service environments.
