L'API 5CT è una specifica per tubi e casing per l'industria petrolifera e del gas naturale, utilizzati per i pozzi. Questa norma specifica le condizioni tecniche di fornitura per i tubi in acciaio (casing, tubing e giunti pup), il materiale di accoppiamento, il materiale di accoppiamento e il materiale accessorio e stabilisce i requisiti per tre livelli di specifiche di prodotto (PSL-1, PSL-2, PSL-3).
Grade M65 is a new grade added in the API 5CT new version. It’s is not used often and is the only steel grade among the general-purpose casing grades with the requirement of a restricted maximum hardness. Acciaio WLD is a leading API 5CT casing and tubing manufacturer and supplier, we provide not only a broad range of API 5CT M65 oilfield casing and API 5CT M65 tubing but also casing coupling, perforated pipe and more.
