ESASTSUN OILFIELD EQUIPMENT MANUFACTURING (CAMBODIA) CO., LTD
Couplings are used to connect two joints of tubing coupling or casing pipe together. Couplings are short length of heavy wall pipe with the same threads on each end. EASTSUN manufactures tubing coupling and casing tubing coupling strictly comply with API 5CT latest standard. The steel coupling is mainly used to connect oil pipes in pil drilling. This product can be used to connect the shafts of units that are manufactured separately. It can fit the misalignment of the shafts or introduce mechanical flexibility. The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another. It can also introduce protecyion against overloads. The steel coupling can be used to alter vibration characteristics of rotating units

api l80 13cr oil casing and tubing Tubing is mainly used to provide oil and gas flow passage during production of oil and gas wells. For flowing wells, due to the large inner diameter of the casing, the casing is directly used for production. Due to the density difference, pressure drop and expansion, the liquid flows up rapidly, causing the liquid to slip, resulting in the ineffective utilization of the downhole elastic energy. Running tubing with smaller OD and ID during production can...
api 5ct l80 13cr casing and tubing According to the manufacturing process, oil pipes can be divided into seamless pipes and electric welded pipes. Seamless pipe is a kind of forged steel pipe without welding seam, which is made of hot working steel. After pressing, stretching, heat treatment and other processes, it reaches the standard size of oil pipe, forming a seamless oil pipe series. Electric welding pipe is a kind of pipe with a longitudinal weld formed by resistance welding or electric...
