Basic Info:
Model No.: AW BW NW HW PW
Technique: Cold Drawn
Usage: Special Purpose, Mining
Dimension: Wireline and Conventional Core Barrel
Origin: Wuxi, China.
Type: Seamless
Standard: DCDMA
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.
Raw Materials:
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.
