NOV Quality Tubing services all lines of coiled tubing both at its Houston headquarters and at Service Centers established at strategic locations worldwide. These satellite Service Centers stock standard strings and perform a variety of operations, including spooling, cleaning and wireline operations. Many of these services are performed both at the Service Center itself and at field locations.

NOV Quality Tubing's Service Centers perform the operations up to QT's standards and specifications. This system assures that customers will receive the same level of quality and service that they do from the Houston facility while having a quicker response time in receiving the service. The strategic location of the Service Centers permits customers outside of the United States to perform regular maintenance on the string which can extend the life expectancy and detect any possible damaged or highly-fatigued areas of the string.
