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 P110 Casing Tubing is an API 5CT oil труба для корпуса and mostly utilized for general use in deep wells with varied end connections such as non-upset ends or an external upset end. WLD steel is a leading API 5CT casing and tubing manufacturer and supplier, we provide a broad range of API 5CT P110 oilfield casing pipe, API 5CT P110 tubing but also casing coupling, perforated pipe, and more.
