HC grades are an enabling technology for wells exposed to high external pressures (formation, temperature…)
Cost effective solution
Don’t go to the next weight up because of high external pressure, use High Collapse grades
Highest proven performances
Decades of know-how and process control backed-up by thousands of test results for the highest and safest ratings on the market
"All the way back to the early days of the Mannesmann process, the engineers from R&D, Process and Production collaborated to define process controls and develop models providing the highest and yet safest collapse ratings on OCTG tubulars for our most technical customers."
