what is ISO 3183 oil and natural gas pipelineJanuary 3, 2017
ASTM A179 seamless steel tube,Cold-Drawn Low-Carbon Steel pipeJanuary 6, 2017
API 5DP SPEC drill pipe is a type of steel pipeline with screw thread in the pipe end. It is utilized for linking ground rig devices and drill grinding equipment at the bottom of drilling wells. The main function of drill pipes is to transfer drilling mud to the drill bit. It rises, decreases and turns together with the drill bit. Its strength must withstand the pressure, torque, vibration and other forces caused by the drill hole. In the oil and gas exploration and refining procedure, API 5DP drill pipe can be utilized for several times. JST supplies a variety of drill pipelines readily available in different sizes and weights to satisfy the drilling requirements of business in the oil and gas market.
