With the growth and development of China domestic construction enterprises, many enterprises have purchased foreign
large-scale drilling rigs, but the drill Rods/pipes used by these drilling rigs have special threads, which are difficult to
purchase in China with high prices abroad and long delivery time. The series of drilling tools produced by our company
can match the roller rigs produced at china and abroad, such as KY200, KY250 and KY310 produced by Hengyang
Metallurgical Mechanical Plant; KY200B, KY250D and KY310A produced by Jiangxi Kama; Atlas Production of PV235,
CDM75, CDM30, DM45, PV275, PV351, ECM695/760/780, DML series, CUBEX drilling rig, etc.
We can not only produce rotary drill pipes with API standard threads or special threads in different lengths, diameters,
wall thicknesses and materials, also produce drill rods according to materials, lengths, wall thicknesses and threads
required by customers.
we can complete the processing of 3-1/2" HXCO(Interchange with BECO), 4 "HXCO, 41/2" HXCO, 51/4 "HXCO, 6" HXCO,
6/8 "HXCO, 8" HXCO, 10 "HXCO, CUBEX 21 #, CUBEX 24 #, CUBEX 28 # and other proprietary threads as well as API
series threads.
Rotary drill pipe is mainly used in large diameter hole drilling in large open pit mines.
