Wireline Drill Rods

Wire line Drill Rods with DCDMA standards Heat treatment control 3m /1.5m

The drill rods and casing tubes are manufactured from the highest quality material, under stringent industry DCDMA standards, and are field tested under a variety of conditions, in order to meet the most rigid demands in during performances and in manufacturing standards.

We will make sure the compositions and specifications match the inspection report form the suppliers.

Raw materials:

30CrMnSiA/XJY850 

We only choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. 


Heat treatment control: 

Entire-length or ends thermal processed will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body, ensuring superior wear resistance, strength, and toughness in the most demanding applications.


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. 


Additional thread treatment: 


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. 

Size available as followings:


Wireline series: AQ, BQ, NQ, HQ, PQ
