Our drill pipes are of high physical property, for their strictly controlled processing of sulphur and phosphorus. To ensure the materials to meet even surpass the requirements of API Specification, heat treatment is on the basis of the actual chemical analysis of each heat of steel. Strict full-length inspection especially on the weld-neck region ensures the drill pipes are of no defects.
All threads are machined by CNC Lathes and inspected with API Spec standard thread gauges. To improve the galling-resistance during initial break-in and drilling operation, all threads are also phosphated or coppered, and all the roots are cold rolled. The products shall be equipped with pressed steel or plastic steel thread protectors on the connections.
Our company will always keep the various demands of broad customers in mind and provide the best service end-users.
