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.

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.
