PR2 Wellhead And Christmas Tree

Sanjack’s wellhead and tree plant is one of the main subsidiaries of the Sanjack Group.  Is a professional manufacturer specializing in the development, design, production, remanufacturing, maintenance, sales and service of wellhead and tree.  Our existing staff 185 people, all kinds of large and medium-sized mechanical processing equipment more than 200 sets, annual production equipment 3500 sets.

  • Sanjack designs various types of wellheads and trees according to API SPEC 6A and 16A.
  •  Use 3D software to perform pressure analysis on pressurized and stressed parts to check the strength of wellhead and tree.
  • The wellhead and tree underwent rigorous testing, such as magnetic particle, ultrasonic, pressure testing, etc.

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.
