石油天然气作业要求阀门能够承受极端温度、腐蚀性介质、爆炸性环境，并提供免维护的长期可靠性。HGZK为产业链每一个环节提供定制化解决方案。
Wellhead pressures up to 10,000 PSI, temperatures from -196degC to +650degC. HGZK valves utilize duplex stainless steel, Inconel alloys, and hardened trim materials. Fully API 6A / API 6D certified for zero-leakage performance under extreme duty.
Sour gas (H2S), CO2, chlorides, and abrasive media aggressively attack valve internals. NACE MR0175/ISO 15156 compliant materials combined with Stellite hardfacing extend service life by 3x compared to standard trims.
Zone 1 / Zone 2 hazardous areas require ATEX/IECEx certified actuators. HGZK electric actuators achieve Ex d IIC T4 rating. Pneumatic actuators feature SIL 3 certified emergency shutdown (ESD) functionality with spring-return fail-safe action.
从上游勘探到下游炼化，HGZK覆盖油气产业链每一个关键环节。
Wellhead control, Christmas trees, water injection, gas lift systems
Forged steel gate valves & slab gate valves per API 6A. Metal-to-metal seal design for subsea trees and onshore HPHT gas wells. Hydraulic/pneumatic actuated for remote shutdown capability.
High-pressure multi-stage control valves with precise Cv modulation. Cage-guided anti-cavitation trim for injection pressures up to 35 MPa in secondary recovery operations.
Pneumatic / electro-hydraulic ESD valves, SIL 3 safety integrity. Spring-return fail-safe mode, closure time under 1 second, meeting API 6D Fire-Safe requirements.
Long-distance pipelines, LNG terminals, tank farms, distribution stations
Fully welded ball valves with 30-year buried service design. Double piston effect seats with DIB-2 dual isolation. Electric actuated for SCADA remote control.
-196degC cryogenic ball / butterfly valves in CF8M/CF3M cast body. Lip-Seal design with extended bonnet for packing protection. BS 6364 cryogenic tested.
API 607 fire-safe ball valves with pneumatic actuators and fusible link triggers at 100degC. Limit switch position feedback with solenoid valve control package.
CDU, FCC, hydrocracking, ethylene cracking, aromatics complex
High-temperature slide/plug valves operating at 700degC+. Refractory-lined with pneumatic positioning accuracy of +/-0.5%. Purge system prevents catalyst coking.
Class 2500 cage-guided control valves with INCONEL 625 overlay trim. Multi-stage pressure reduction, noise below 85dBA. For hydrogen and high-temperature sour hydrocarbon service.
Full-bore high-temperature ball/gate valves for 900degC steam decoking. Metal-seated with graphite packing combination for rapid on-off switching during furnace decoking cycles.
