Description:
Wire line Drill Rods With DCDMA standards Heat treatment control 3m
/1.5m
Our PWL 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/ ZT850
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 our company.
Heat treatment control for PWL Drill Rod:
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: AWL, BWL, NWL, HWL, PWL
Casing: AW, BW, NW, HW, HWT, PW
Chinese Standard: S56, S59, S75, S95, S110, S130, S75A, S95A
1. We have been strictly controlled the quality of our raw
materials, and all of our steel metals are from famous steel mills
(factories). And physical metallographic analysis and chemical
composition test are also used to ensure the quality of raw
materials.
2. Immediate inspection will be done for each production procedure,
and full examination will be implemented for threaded products.
3. Our outsourcing products will also be strictly examined before
utilization.
4. Our sampling rate for final products is higher than 30%.
