Product Details

Deep Foundation Drilling Oil Drilling Pipe , Drill Stem Pipe Long Life Span

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.

 

The drill pipe produced by our company is made of high-end technology. The steel of drill pipe body and joint is selected with high quality materials. Meanwhile, metallurgical technology is strictly controlled to increase hardenability of steel and ensure uniform microstructure and mechanical properties and good weldability. Ensure uniform and uniform hardness, increase the toughness of the material and improve the fracture toughness of the steel. Thus, the performance stability of the drill pipe is improved and the consumption of drill rod is reduced, which provides convenience for the majority of customers. Get the approval of the vast number of customers.

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.
