PR2 wellhead and christmas tree
Sanjack’s wellhead & x-mas tree factory is one of the main branches of Sanjack Group. It is a professional manufacturer specializing in the development, design, production, remanufacturing, maintenance, sales, and service of wellhead & x-mas tree. The factory has 185 employees, more than 200 sets of various large and medium-sized mechanical processing equipment, the annual output of 3500 equipment.
- Sanjack designs various types of wellhead & x-mas tree according to the API SPEC 6A and 16A standard.
- Do the pressure analysis to pressured and forced parts with 3D software to check the strength of wellhead & x-mas tree.
- The wellhead & x-mas tree has carried out rigorous tests, such as magnetic particle, ultrasonic, pressure test and and so on.
The wellhead and X-mas tree valves produced by Samjack all conform to the API 6A PR2 standard.
PR2 wellhead is designed to suit severe oilfield conditions.
It is mainly used in oil/gas wells with high performance requirements.
The performance of all the wellhead equipment are verified by DNV verified including the casing head housing, casing head spool, tubing head spool and cross, gate valve and choke valve.

1)PR2 Gate Valve
PR2 gate valve is mainly used in the PR2 class wellhead and X-mas tree. It controls the opening and closing of fluid in the production process and is one of the core components of the wellhead and X-mas tree. However, PR2 class wellhead and X-mas tree with high pressure are always the disadvantage of Chinese oil wellhead equipment manufacturers due to their high design, manufacturing and test requirements. After two years of development and testing, sanJack gate valves have finally passed PR2 validation.
