Oil Production Tubing Head Assembly

The production tubing head assembly is a vital load‑bearing and sealing component within wellhead systems, designed to support the tubing hanger and isolate annular pressure between tubing and casing, fully compliant with API 6A and NACE MR0175 standards. Unlike simple tubing spools with limited sealing capability, this integrated unit combines a robust forged body, tubing hanger and multi‑stage sealing packages. It reliably sustains working pressure up to 25,000 psi and maintains long‑term sealing stability under continuous oil production conditions. Its precision‑machined sealing surfaces and modular construction eliminate custom on‑site machining and reduce installation errors. It offers reliable compatibility with onshore and offshore oil well layouts, overcoming the poor sealing stability of conventional tubing heads.
