The wellhead and X-mas tree valves produced by Sanjack 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.
Geothermal wellhead equipment is the most basic wellhead equipment in geothermal well development. It is necessary to maintain the normal operation of geothermal well production, conduct dynamic monitoring of hot water, prevent accidents caused by well pipe expansion and ground descent, and reduce the corrosion effect of hot water. With the gradual development of geothermal utilization, the wellhead devices of geothermal wells are gradually standardized
