Water Injection Wellhead

The water injection wellhead assembly is an essential pressure‑holding and fluid‑delivery component of the wellhead system, designed to deliver pressurized injection water into the reservoir for reservoir pressure maintenance and EOR, fully conforming to API 6A and NACE MR0175 standards. Unlike simple pipeline fittings, this integrated unit combines sturdy spool body, tubing hanger and reinforced sealing system to sustain long‑term continuous water injection under stable working pressure. Its precision‑finished sealing surfaces and modular construction avoid on‑site reworking, lower installation errors and adapt to onshore and offshore water flooding projects, where conventional injection assemblies lack reliable long‑time sealing performance.
