Our PWL drill pipes and casings are made of the highest quality materials and comply with the strict industry dcdma standards. They are tested on site under various conditions, and have the most stringent requirements in meeting the performance and manufacturing standards.
We will make sure the compositions and specifications match the inspection report form the suppliers.
We only choose the best steel pipes in the market to manufacture our bars and tubes. After the steel pipes are delivered to our company, random inspection will be conducted.
Heat treatment control for PWL Drill Rod:
The whole length or end of the heat treatment will greatly improve the material strength and prolong the thread wear life of the rod and sleeve. We conduct tru wall or end heat treatment on the pipe body to ensure excellent 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.
