DTH drill pipes play a big role all told DTH drilling, regardless
of application, rock type, hole depth or drilling rig. The key
options of a prime quality DTH tube are durability, accuracy and
manageableness. DTH drill pipes are made of superior alloy and both
thread ends are friction welded to the seamless steel pipe.The high
pressure is delivered to DTH hammer by DTH drill pipe, at the same
time it transfers the rotation and press force to the DTH hammer.
Applications
Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
We can also provide related products DTH hammers, ODEX system,
symmetrix systems, slide block drilling systems, etc and DTH
drilling pipes for various thread API REG, API IF, BECO, etc

FAQ
1. The Quality of Drill bit?
We have many series of rock bits,quality grades are different,and
prices are different.We believe,the proper tools with higher
cost-performance isthe most impormant.For example,our top quality
rock bits is not cost-effective for water well drilling,as the
water well drilling machine can not drive the super rock bit to
perform their best.but for very deep well drilling high quality
gradesrock bits is cost effective even its price is much higher.So
it is better tell us as more as possible the details of
projects,then we provide the proper solutions and offer,usually 2
or 3 solutions wil be provided for options.
2. How to send inquiry?
It is better send us detailed specificaltions of products,it is
better attaching some photos for better understanding.If you are
not experienced on drilling fields,for example,many customers don't
know IADC code,please feel free,jusst tell us the applications like
oil/gas/geothermal/HDD/ware/mining,depth of well,average hardness
of rocks,then we will advise suggestions and solutions.
