Today, oil and gas wellhead pressures can reach up to 20Kpsi, H2S and CO2 at high temperatures, sand particles and other impurities create very challenging conditions. Chemical injection, water injection and other methods are widely used in the fracturing and oil recovery technology of shale gas exploitation, which increases the requirement for corrosion resistance of valve products. Professional design, accurate material selection (metal seal and soft seal) and advanced surfacing and surface treatment technology enable SUNE valves product quality and technology to continuously meet the increasingly stringent working conditions.
