Description
The square threads of coupler and pipes designed for DCP Column Pipes are made in the last generation threading
machines. By thickening the pipe ends with special production methods, the safe wall thickness value of the pipe is maintained
after threading. Special adhesive is used to fix the coupler to the pipe. Sealing is provided with o-ring seal used
between pipe and coupler. With the tightening torque applied during the well assembly, the pipe head parts contact
each other, creating pretension in the square threads. This pre-tension prevents self-thawing of the teeth.
