Threading

A total of 8 CNC threading machines; making up four threading lines, are used to cut API threaded connections or premium threaded connections with meticulous precision. After a methodical thread inspection the couplings are made-up power tight. Then the tubes are filled with a water/oil emulsion and an appropriate hydrostatic pressure test is performed.
