Оцинкованный корпус API 5CT C110 для соленых условий эксплуатации

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).

Grade C110 is a new grade added in the API 5CT  ninth version, it’s a controlled yield strength grade generally used in deeper sour condensate wells. SSCC testing is required for each heat to meet the threshold stress of 85% of the 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 C110 oilfield труба для корпуса, API 5CT C110 tubing but also casing coupling, perforated pipe, and more.
