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 Q125 is an API 5CT oil ケーシングパイプ grades and mostly used for general use in deep wells with varied end connections such as non-upset ends or an external upset end. Impact testing is required for each heat and/or lot. NDT inspection typically EMI and UT are required on this product. WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide a broad range of API 5CT Q125 oilfield casing pipe, API 5CT Q125 tubing but also casing coupling, perforated pipe, and more.
