introduction

API 5CT H40 casing is a steel pipe that implements the API SPEC 5CT standard of the American Petroleum Institute, and is mainly used for the exploitation of resources such as oil and natural gas. ‌H40 octg casing is part of the full range of API oil casing, and its product specifications include outer diameter and wall thickness range, specifically outer diameter Φ26.67mm~Φ219.08mm, wall thickness 3.18mm~22.2mm. ‌H40 casing is mainly used for well wall support of oil and gas wells to ensure the stability and safety of the well wall. ‌
According to different lengths, ‌H40 Casing Pipe can be divided into three specifications: R-1, ‌R-2 and R-3 to meet different well depths and operation requirements. ‌
In the drilling, production and transportation of oil and gas, API 5CT H40 oil special pipe is usually used in underground casing strings to protect the well wall, isolate the formation, and prevent accidents such as blowouts and well collapses.
