API 5CT is a specification for casing and tubing for petroleum and natural gas industries-used for wells. This Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3).

API C90 type 1 is an API controlled yield strength grade generally used sour for service in condensate wells and the minimum threshold stress required is 80% of specified minimum yield strength. WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide a broad range of API 5CT C90 oilfield ケーシングパイプ, API 5CT C90 type 1 tubing but also casing coupling, perforated pipe, and more.
