Oilfield API Bucking Unit

1. Resume premium thread tubing/ casing coupling bucking unit is the special equipment applied to the processing of premium thread oil pipe. It is also applied to the coupling screw of the premium thread such as FOX, NK3SB,VAM,BGT as well as the common thread . With slight mark and the depth of being less than 0.05mm, the floating arm tong is able to inspect the make-up torque precisely and display the torque of inflection point clearly during the make-up process. It changes speed automatically during the make-up process and the low rotation speed is lower than 5r/min. It is thus applied to the processing demand of premium threads. 2.Equipment composition 2.1.premium thread tubing/ casing coupling bucking unit 1 set 2.2.torque control system 1 set 2.3.hydralic power station 1set Product Description TJA Series of casing and tubing coupling bucking unit is widely applicable for casing and tubing manufacturing, and oil field service. Among which the TJA series is the most representive casing and tubing making equipment with most mature technology and most advanced structure. The bucking unit follows API tubing thread connection requirements, especially suitable for screwin screwout of multiple kinds of coupling. Never-stick gripping mechanism and precise torque-control system provide whole computer moninor during screwing process. Manual, semi-automatic, fully automatic are available, and features large range, high torque, long service life and safe and reliable. The product has awarded national invention patent.
