API 5CT casing pipe application

Octal Steel offers a complete range of API 5CT casing and tubing pipe for kinds of demands in oil exploration and production. Material includes carbon steel (for most common use), alloy, Chrome, and high alloy steels. API 5CT Grades covers J55/K55, N80 type 1 and N80Q, L80, C90, T95, P110, Q125, and with additional requirements of 13 Cr.

API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion wells normal operation. Each well depending on the depth of drilling and geological conditions, to use several layers of casing. After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, a one-time consumable materials. Therefore, the casing consumption accounts for over 70% of all the oil well pipe. According by usage can be divided into the sleeve pipe, surface casing, casing and production casing.
