Wellhead is a critical part of the oil and gas infrastructure. Seals material and design must withstand pressures as high as 15K psi and temperatures LU (-46℃~121℃), PU (-21 ℃~121℃), or SX (-18 ℃~178℃). .Case 4 – Licensee designed test customized for well operations . Test procedures must effectively identify any well integrity concerns or potential failures in the tubing, casing, packer seal, or wellhead seal assembly; meet the minimum pressure and duration requirements specified in table 1 when pressure testing; and be documented. 2.2 RepairingSummary Personnel from a major wellhead manufacturer created simulated severe leaks in wellhead components to test the ability of Seal-Tite® to cure the leaks using Seal-Tite’s pressure activated sealant. Using procedures identical to procedures used in the field, the Seal-Tite® technician was able to cure each simulated leak. The Seal-Tite® seal was able to hold [.]
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 . Annulus seals. The seals used on spool wellhead systems are traditionally elastomeric. This is primarily because the seal must be energized against the casing-bowl ID, and must also seal against the rough finish of the casing OD. . The tool used for testing the BOP is typically a plug type with a heavy-duty elastomer seal. Annulus access. For .

You can trust our FS- and S-seals as well as our T- and Locking T-seals to perform in the most challenging conditions, as they’ve all been through the most rigorous testing program at our own cutting-edge testing facilities. Putting them through extreme examinations means SKF seals meet the highest standards of performance.G.B. Industry offers Wellhead PE Seals & Secondary Seals, including X-Bushing & R Seals, Bit Guides, PE-Pressure Energize, & 4-O Bushing seals. Call an expert today! . Secondary seals provide external testing for the connection. Secondary seals can serve as a pressure crossover by restricting the area exposed to pressure within the spool.
Seal testing. Sound engineering practice dictate that it should be possible to test all seals from the correct direction. External testing of the upper seals checks these seals the wrong way around, as the test pressure in this case comes from below, while the actual well bore pressure comes from above. The reverse situation applies to the . Lockdown Screw packing seal is usually made of an HBNR compression packing element with molded metal end caps. But JST has developed a lockdown screw packing seal which is made of one filled PTFE and two cooper end caps. It is the sealing between wellhead members in a wellhead, inclu ding a seal element and a lockdown member. The seal is .Our core wellhead technologies, such as seals and gate valves, provide exceptional reliability and integrity for all our wellheads in both low-temperature and high-temperature operations.
