Water Injection Tubing Head Assembly

The water injection tubing head assembly is a key load‑bearing and sealing wellhead component engineered for water flooding operations, fully conforming to API 6A and NACE MR0175 standards. Unlike general‑purpose tubing heads built for hydrocarbon production, this integrated assembly adopts a rugged forged body, dedicated tubing hanger and reinforced sealing packages to handle long‑term continuous water injection. It can reliably contain working pressure up to 25,000 psi and prevent injected water from escaping through the annulus. Precisely finished sealing surfaces and modular design remove the need for on‑site fabrication and lower installation faults. It delivers great adaptability for onshore and offshore water‑injection well systems, making up for the insufficient erosion resistance of conventional tubing heads under water‑flood conditions.
