API 5CT H40 OCTG Casing

API 5CT H40 casing is threaded, the main purpose of which is that it can shorten the downhole time. Casing is a disposable material, which will lead to great loss if any problem occurs in use, so the quality requirements for casing are extremely strict.
The special products of API 5CT H40 casing include special buckled casing and casing with special material and performance such as anti-sulfur, anti-corrosion, anti-extrusion and so on. Special buckled casing is mainly used in deep well cementing where the tensile strength of ordinary casing does not meet the requirements, and is generally used only for a period of time at the wellhead; sulphur-resistant and corrosion-resistant casing is mainly used in deep wells and ultra-deep wells in sulphur-containing oilfields; and anti-destructive casing is mainly used in oilfields with high squeezing pressure, which requires the casing to have good mechanical properties and destructive properties of the casing in deep wells and ultra-deep wells.
