After heat treatment, strength, hardness, straightness and concentricity of the treated tubes will be tested in our lab.

Thread opening process:

Accuracy of threads will determine the use effects and life time of drill rod and casings.

CNC latches and form cutter are used in thread opening processing to minimize error made by anthropic factors.

Surface of the threads will be cleaned to remove burr adhered after threads are opened.

Afterwards, the tread surface will be phosphated to improve surface conditions.
