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).

In the API 5CT version 9,  the chapter “Manufacturing method and Chemical Composition Requirements” removed C95 steel grade and increased R95, C110 (seamless tube only). API Grade R95 has the same yield strength range and tensile strength as API T95 but without the requirement for SSC or hardness tests, generally not for use in condensate wells since no hardness restrictions is required.  Steel grade R95 is a better-priced alternative to T95 in wells without the risk of sulfide stress cracking. WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide a broad range of API 5CT R95 oilfield ケーシングパイプ, API 5CT R95 type1 tubing but also casing coupling, perforated pipe, and more.
