Collapse-resistance Casing

Collapse-resistance Casing:High resistance to collapse of oil casing For special well conditions such as shale gas, salt gypsum layers, mudstone layers, and oil layer sand production, it can generate significant or uneven external compression loads. These requirements can be met by optimizing the chemical composition, heat treatment process, mechanical properties, etc. of the material. Recommended grades: 80TT Collapse-resistance Casing, 95TT Collapse-resistance Casing, 110TT Collapse-resistance Casing.
