Drill pipes are widely used in mining,geological exploring and all kinds of drilling(water,oil,gas,etc) projects.As a leading drill pipe manufacture,we make all kinds of standards and non-standard drill pipes for our customers. Our drill pipes including steel drill pipe,mining drill pipe,water well drill pipe,oil well drill pipe,API drill pipe,DTH drill rod,wireline drill rod,etc.
Applications
This DTH drill pipe, the shortened form of down the hole drill pipe, is a kind of outer flat drill rod. It is mainly used in rotary percussive drilling that contains gases and liquids. Its main components include pipe (rod) body and joint.
Our down the hole drill pipe is manufactured based on the API standards. And according to specific requirements, we also provide this kind of DTH drill pipe in different Chinese and American specifications.
As for its advantages, it has features of big rigidity, good sealing capacity, flat outer structure, and low torque and resistance when rotating.
As to the packaging, a bundle of DTH drill pipes will be packed by one set of steel frame, and a bundle will have 30 to 40 drill pipes.
HDD Horizontal Directional Drill Pipe /Rod for Trenchless Drilling>>HDD Friction Welding Drill Pipe Thread type and the length of drill pipe can be manufactured according to users' requirement.
>>Material selection-with API standard and reliable performance.
>>The twice thickening molding technology of pipe joint makes the transition zone very stable and smooth which tremendously reduce the resistance of mud through the pipe.
>>With National initiative integral drill rod and intermediate-frequency heat treatment technology make this kind of product have the higher Mechanical Properties than the similar products.
>>Be treated by liquid nitrogen treatment process, the joint thread is deeper than the traditional processing technology which greatly prolong the service life of products.
