Tri-arc ridge-type gas drainage drill pipe, drill pipe short triangular, mainly round drill pipe, spiral drill alternatives, using the triangular hollow circular rib steel pipe structure, with its unique transmission connection, effectively solve the problem of stress concentration. Compared with conventional drill pipe, drill pipe in the new Tri-drilling process, stirring cinder effective borehole drilling residue around the axial movement of the drill to do, and get crushed slag drill and raised, so that in suspension, without precipitation, accumulation. Production process: Tri drill made of high quality carbon steel pipe for drilling levers body 42crmo joints at both ends of high quality materials, the high pressure processing molding, true air conditioning and tempering. Adopt international advanced interference welding assembly process, to avoid quality problems because they can not use the friction caused by the welding process of welding, compared with similar products greatly improve the mechanical properties of the product and the ability to adapt to the complex geological conditions of deep hole drilling. Drill Pipe Specifications: The product is simple to use and efficient operation, with a variety of drilling rig, without modification. Model mainly: φ42, φ50, φ63, φ73, φ80, φ89 and other specifications, drill length (mm): 800 ~ 1500; Connection: tapered thread; recommends drilling depth: 50 ~ 180m; torque (nm): 6500; triangular drill, using the latest technology, the Tri-drill with wear wear, overall long life, easy to break and bend, quick and easy installation and removal, saving time and effort. Tri-arc ridge-type gas drainage drill pipe, drill pipe called triangular. Performance parameters header into the form tapered thread type, high pressure type and triangular thread sealing plug type. This product is made of high quality carbon steel pipe for drilling levers body 42Crmo joints at both ends of high quality materials, the high pressure processing molding, true air conditioning and tempering. Adopt international advanced interference welding assembly process, to avoid quality problems because they can not use the friction caused by the welding process of welding, compared with similar products greatly improve the mechanical properties of the product and the ability to adapt to the complex geological conditions of deep hole drilling.
