Air-Sealed Well Control Equipment Solutions


In view of the operational needs of drilling and developing natural gas in high-pressure gas fields, well control equipment is required to achieve gas sealing. Our company can provide supporting solutions for well control equipment such as high-pressure gas-sealed blowout preventer groups and manifolds.


Technical Introduction
The high-pressure gas sealing performance of well control equipment meets the requirements of relevant standards and is at the leading level in the industry. The sealing of high-pressure gas is different from water sealing. It has higher requirements for sealing structure, sealing materials, surface roughness of metal sealing surface, and surface corrosion resistance.High-pressure gas sealing is extremely special, providing customers with targeted solutions for gas sealing. Our company's high-pressure gas sealing blowout preventers, manifolds, etc. have the following characteristics:
The sealing structure is advanced, and high-pressure gas sealing can be achieved without excessive side door bolt tightening torque, and the sealing is stable and reliable;The key sealing materials such as rubber core, side door seal, gate shaft seal are made of special rubber that meets the requirements to meet the gas sealing requirements under high pressure;The key sealing parts are treated with special processes or surfacing corrosion-resistant materials, with excellent anti-corrosion performance;The key sealing parts adopt advanced processing technology, with high surface finish and stable high-pressure gas sealing.
