API spec casing tube Surface oil casing-protects drilling from contamination by shallow water and gas formations, supports wellhead equipment and maintains casing weight in other layers. Technical oil casing-separates different layers of pressure so that drilling fluid flows normally and protects production casing.-for installation of backburst devices, leak preventer and tailpipe in drilling. Reservoir casing-Extracts oil and gas from the underlying reservoir.-used to protect drilling and stratify drilling mud.
The outer diameter of the casing is usually 114.3 mm to 508mm. The API casing has a hollow section. The Chaoyang N80-1 casing is widely used as a conduit for conveying fluid, such as oil, natural gas, water, etc. Using steel tube to manufacture annular parts can improve material utilization, simplify manufacturing process, save material and working time, such as rolling bearing ring, Jack sleeve, etc. At present, it has been widely used in steel pipe manufacture.
