Octg Api 5ct Casing Coupling
Tianjin Richsen Technology Co., Ltd produces API 5CT casing couplings made from carbon and alloy steel in the grades N80, L80 and P110. The couplings are seamless steel components designed to join casing strings in oil and gas drilling operations and meet the API 5CT specifications for high‑pressure downhole environments. They are supplied as threaded connectors and are packaged in bundles or pallets for international freight, with the HS Code 7307.29 used for customs clearance.
Typical size ranges for these couplings cover DN 4 to DN 24 inches, which aligns with standard casing dimensions used worldwide. Tensile strength values correspond to the grade‑specific requirements set out in API 5CT, and the products can be finished with typical epoxy or zinc‑rich coatings for added corrosion resistance. The supplier mentions that the couplings are engineered for stability and performance, making them suitable for demanding drilling projects.
Importers such as drilling contractors, well service firms and equipment distributors source these couplings to ensure reliable connections in well construction. Trade generally involves wholesale quantities, and buyers should confirm minimum order quantities, lead times and Incoterms directly with Tianjin Richsen Technology. Prospective purchasers are encouraged to request the ISO and CE certification documents and API 5CT test reports before finalising any agreement.
