NJ508-70
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 0.1mm, 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 10r/min. It is thus applied to the processing demand of premium threads.

premium thread tubing/ casing
coupling
bucking machine:
The
stepless speed change
can be realized by adjusting the power tong
to rotate in any speed
within
the range of 0.5r/min~12.5r/min in
combination
with
electrical control system and hydraulic power system. During making-up, the speed inversely slows down as the torque increases, it rotates at a high speed when the
torque
is small for the purpose of ensuring the
making-up efficiency, when the torque
is
large, the speed will steadily
slow down, which strictly meets the API Specification, ensuring
the making-up process not exceed the set torque .

ZKN-N803
torque control system:
ZKN-N403
torque control system: TPC for short, is an advanced torque signal processing control and record system which can be used to measure, display, record and control torque when making up the tubes so as to ensure the best screw torque is achieved in the tube joints and all curve data of all joints in screw tightening period are stored in the disc for later search.
