The rotary impact drill pipe is mainly used in rock drilling and crushing, anchoring drilling, geothermal air conditioning hole, water well drilling, etc. The pipe body is made of materials produced by well-known large-scale iron and steel enterprises in China, and the two ends of the pipe body are internally thickened and tempered after friction welding,
It is mainly used in rock drilling and crushing, anchoring drilling, geothermal air conditioning holes, water well drilling, etc. The pipe body is made of materials produced by well-known large-scale iron and steel enterprises in China. The two ends of the pipe body are internally thickened, tempered after friction welding, quenched and tempered after rough machining of drill pipe joints, phosphating and nitriding after finishing. It effectively eliminates the failure probability of gluing, broken buckles, outer diameter swelling and cracking, is more wear-resistant and easy to disassemble. All threads are processed by precision numerical control lathes with customized forming knives. All threads are equipped with thread gauges conforming to international standards. Therefore, the quality of drill pipes produced is stable and reliable, and the service life is greatly prolonged.
Trenchless drill pipe is mainly used in horizontal directional drilling pipeline crossing and laying engineering. The pipe body is made of special materials conforming to API standard, with stable performance. The pipe section thickening conforms to API5DP standard. The thickened pipe body is tempered and heat treated, and the steel grade can reach G105 or S135.
The API standard adapter is used in rock drilling and crushing, anchor drilling, oil drilling, geological water well drilling operations, for the conversion connection of drill string components, is one of the main tools to connect the upper drilling tool and the lower drilling tool.
The lock joint is made of 35CrMo or 42Cr material, heat treatment after rough machining, surface nitriding treatment after finishing...
