Anti H2S Wellhead And X-mas Tree
H2S is corrosive to most equipment and will detrimentally affect the health of personnel, so, basing it design on the API 6A Wellhead and X-mas tree, Shengji developed an anti-H2S wellhead and X-mas tree for H2S removal.
Its main usage is in deep wells, ultra deep wells, and high pressure oil/gas wells with significant H2S levels. It also may be used in high pressure acidization and fracturing in oil and gas wells.
