Oil & Gas Production
High cycles, high temperatures, heavy solids, sky-high hazards and high pressure are everyday, extreme conditions for valves in this field.
Cornerstone Valve has solutions for your most extreme
In an industry where reliability is a must – Cornerstone Valve was called in to turn around an operation where 5200 valves were installed and more than 4000 were inoperable!
High temperature ranges in the industry require specific materials, such as hard-facing cobalt-based alloys. Even bolts have to be carefully selected – high temperature rated or not.
Each part of our valves has a certificate verifying the chemical makeup, yield/tensile strength, heat treatment and place of origin. Standard testing at Cornerstone Valve requires full cycling of valves, under a range of pressures. We provide full testing documentation along with certifications. You can rely on valves to work if they are Cornerstone.
In a major oil field find in South America, the operating company needed to maintain field production pressures by compressing and re-injecting natural gas.
Cornerstone was called upon to supply the high pressure (API 10K) hub-end ball valves in several sizes. After several years of operation, a number of other brands of valves developed multiple seal failures causing both leak-through and external leaks. But not Cornerstone’s!
Cornerstone’s trunnion mounted valves continue to work – many installed more than 15 years ago.
