Shengji api spec 6a pr2 wellhead x-mas tree for oil drilling
api spec 6a pr2 wellhead x-mas tree for oil drilling
Product DescriptionShengji’s offshore wellhead and X-mas tree is designed to solve the problem of space limitation faced in offshore platform oil and gas wells, and adopts a complex integral design. This offshore wellhead and X-mas tree is usually machined from one steel bar, thus decreasing the overall height of wellhead and X-mas tree equipment. To increase its safety, this equipment is fitted with a hydraulic safety valve.
The equipment has an integral BIW cable type and three single cable types to suit different requirements.
Key Feature1.Combined master valve and swab valve to decrease the offshore wellhead & X-mas tree height
2.Hydraulic safety valve in main drift diameter to achieve remote shutdown of wellhead in an emergency
3.Segregated tubing head spool. Top and bottom parts are connected by insert type locking piece. This structure means the X-mas tree could be adjusted in any direction during installation.
4.Equipped with BIW cable penetration and fitted adapter flange and hanger.
