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 Grade T95 has the same yield strength as API C95 generally for use in sour condensate wells. 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 T95 oilfield casing pipe, API 5CT T95 type1 tubing but also casing coupling, perforated pipe, and more.
