W-Series Casing Overview:
W-series casings are madeas per DCDMA standards, the most popular sizes are AW, BW, NW, HW and PW, which are widely applied in geotechnial drilling.
We choose the best steel tubes in the market to manufacture our rods and pipes. Instant check will be conducted after the raw material is received in our factory so that it can make sure the compositions and specifications meeting applicable stardard requirements.
Heat Treatment Control:
Heat treatment will greatly make sure the material strength and the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body.
Thread Opening Process:
Precision of threads will impact the use effects and serve time of drill rod and casings.
CNC latches and form cutter are used in thread opening process to minimize error.
Additional Thread Treatment:
Surface of the threads will be cleaned to remove burr adhered after threads are opened.
At last , the tread surface will be phosphated to improve surface conditions.
Casing and Core Tube Specifications:
Length and threads depend on
1. Our wireline drill rods are of the highest quality and manufactured to exacting specifications using advancing maching technoogy.
2. They are manufactured from seamless steel tube by cold drawn. The material is XJY850/30CrMnSiA which meets the global standard.
3. Drill rods are made from quality heat treated materials which ensure superior strength, wear resistance and toughness in the most demanding applications
4. Rods and casing are manufactured under stringent industry standards, and are field tested under a variety of conditions.
5. All rods are designed to be compatible with the standard DCDMA.
6. Our NQ drill pipes/drill rods got most praise from oversea market.
