OCTG casing and tubing
April 14, 2020
Casing and tubing strings are the main parts of the well construction. All wells drilled for the purpose of oil or gas production (or injecting materials into underground formations) must be cased with material with sufficient strength and functionality.Oil country tubular goods (OCTG) is a family of seamless rolled products consisting of drill pipe, casing and tubing subjected to loading conditions according to their specific application. In oilfield tubing and casings, thread profiles are designed and manufactured in order to provide superior hydraulic seals between the equipment and pipes. There are several types of Casing Threads used; they include: Ⅰ.Buttress […]
