Rod handlers improve safety by keeping helpers away from energized components and potential injury from wrenches under power. Coring rod threads will jam in 20-30% of joint make-ups, meaning that time is lost, and 5% of the time the helper is back near the rotation unit, reducing safety. These jams add significant unproductive time either to unjam threads or rotate threads backward 100% of the time when manually making joints.


Our wireline rods feature a unique thread entry, nearly eliminating jams, upgrading safety for hands-free rod handling, where making and breaking of rods is mechanized. The threads also feature a coarser pitch with less rotation, making them faster to make up by hand, generating less fatigue, lower stress on the wrist and less potential for repetitive use injuries.

Features:  


1. Made from high-precision, stress-relieved seamless steel tubes

2. Wireline drill rods with heat-treated ends to strengthen threaded joints

3. Precision-machined, gauged and treated to mitigate galling

 

Raw materials: 


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


Heat treatment control:

Heat treatment 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. 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.



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.
