Product Description
>>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.
Drill rod details
Rod body adopts famous domestic large-scale iron and steel enterprise production materials, adopted in the thickening process on both ends of the pipe body, has carried on the tempering process after friction welding, pipe joint and tempering heat treatment after rough machining, finish machining after surface nitriding treatment, effective to eliminate the thread gluing failure probability, burst fracture, diameter, etc, more wear-resisting, easy to remove.
All adopt the precise import numerical control lathe, the custom-made molding tool to process the thread, all the threads are equipped with the thread gauge that conforms to the international standard, so the production drill pipe quality is stable, reliable, the use period is greatly extended.
