Product Introduction:
For special well conditions such as shale gas, salt paste layers, mudstone layers, and sand production in oil reservoirs, significant or uneven external squeezing loads may occur. Henggang has independently developed a series of high anti extrusion casing with higher performance than API Spec 5CT casing of the same specifications and steel grade by optimizing the chemical composition, heat treatment process, mechanical properties, etc. of materials. It has been widely used in major oil fields at home and abroad.
