Corrosion Resistant Gas Wellhead Christmas Tree For Natural Gas Well
Product Description
Our API 6A Gas Wellhead Christmas Tree (Gas X-mas Tree) is dedicated wellhead equipment for onshore natural gas exploitation, shale gas, coalbed methane and gas well testing. The classic Y-type flow channel design optimizes gas delivery and avoids liquid accumulation. The whole set consists of tubing head, casing spool, production wing, kill wing, manual gate valves, pressure gauge connectors and bleed manifolds. It controls gas output, monitors well pressure and implements emergency shut-in to guarantee safe gas field production. All products pass factory hydrostatic pressure test and comply with international oil & gas standards. Custom pressure, material and structural configurations are available for various well conditions.
Product Features
- Standard API 6A certification, PSL1/PSL2/PSL3/PSL4 compliance, meets global oilfield procurement standards
- Optimized Y-type main flow path: smooth gas circulation, low turbulence, less condensate accumulation
- High-strength forged carbon steel/alloy steel body, high pressure resistance, long service life
- Optional anti-H₂S sulfur-resistant material (NACE MR0175) for acidic gas fields with hydrogen sulfide
- Metal-to-metal primary sealing structure, stable sealing performance under ultra-low temperature & high pressure
- Multi-channel independent valve layout: separate pipelines for production, killing, venting, sampling & chemical injection
- Full outdoor anti-corrosion coating, anti-rust, resistant to desert, alpine and saline-alkali environment
- Manual large handwheel gate valves, easy operation, convenient daily maintenance and parts replacement
- Safety interlock valve design to prevent misoperation and gas leakage risks
- Compact integrated optional structure, saves installation space for small single well sites
Main Working Functions
- Gas production control: Adjust, throttle and fully shut off natural gas output stably
- Well pressure monitoring: Reserved gauge ports to read tubing & casing pressure in real time
- Emergency blowout prevention: Quick shut-in to block gas overflow under abnormal well pressure
- Well testing operation: Support temporary opening, gas sampling and flow measurement
- Wellbore maintenance: Kill fluid injection, chemical corrosion inhibitor injection
- Liquid drainage & venting: Discharge condensate and excess wellbore gas safely
