SUB BIT 2-3/8 REG BOX *2-3/8 IF BOX 2FT
The oil drill pipe is connected end to end through threaded joint, so as to realize the transmission of torque and coolant in the drilling process. It is the main equipment in the process of oil exploration and production. The working condition of drill pipe adapter is bad in drilling process, which is the area where drill pipe is more likely to fail, so it is the key to determine the quality and service life of drill pipe. The forming process of drill pipe is as follows: round steel blanking → annealing → rough turning → ultrasonic testing → deep hole drilling → quenching and tempering → ultrasonic testing → semi precision testing → thread turning → magnetic particle and dye testing → dimensional inspection, etc.Contact us:Tianjin Forwell Energy Equipment
When the drill pipe is far from reaching the average service life, the fracture failure occurs at the root of the adapter thread. Through the investigation of the drill pipe using process, it is found that the operation of the workers meets the specification requirements and the main equipment is in normal operation. It is preliminarily determined that the fracture failure is caused by the quality of the parts themselves.
Forwell can process many differernt sub bit such as 6-5/8 REG BB*6-5/8 REG BB-3FT and 3-1/2REG BB*3-1/2IF BB-2FT OD 4-3/4 etc
