China Drill Pipes Mainly studies and manufactures high-pressure down the hole impactors, various down the hole drills, drill pipes and drilling tools. The products are widely used in earthwork mining, water well engineering and construction, GEOTHERMAL DRILLING, MUNICIPAL ENGINEERING. Anchor rope drill rod, pneumatic drill rod, single type finished brazing rod, cross type finished brazing rod and other products, the rod body uses 55SiMnMo, 90CrMo high quality hexagonal hollow alloy steel as raw materials, the products are high-pressure calcined, vacuum integral tempering heat treatment.The application of CNC automation equipment processing and molding, to ensure a stable and reliable product quality. B19 drill rod, also known as B19 anchor rod, is used on anchor drill rod. It is divided into bottom joint anchor rod, middle joint anchor drill rod and lower joint anchor drill rod. The drill rod is connected by connecting sleeve.Equipped with a bolt bit.B19 anchor rope drill pipe length is 1 m/piece, 1.5 m/piece, 1.2 m/piece, or can be customized as required.The drill pipe is made of 60Si2Mn high quality hexagonal hollow alloy steel by high pressure forging and vacuum integral tempering heat treatment.Strong bending resistance, strong durability, easy to disassemble and install, easy to operate. The problem is raised and the cause analysis is found through investigation, the use of various types of multi-drill rods connected to down-the-hole drills, rock drilling rigs and other rock drilling equipment in underground mines, the service life of the drill rods is relatively low, and the main failure The form of the connection thread wear, which accounts for a large proportion of the production cost, also has the same problem with the multi-drill rod connection DTH drill. The reasons for the wear of the thread of the drill pipe connection are the poor working conditions of the downhole production, and the presence of sediment in the thread pair of the drill pipe can aggravate the thread wear. The low hardness of the drill pipe thread heat treatment can easily cause the drill pipe thread to wear. . The length of the connecting thread of the type DTH drill pipe is that because the rotation speed of the slewing mechanism and the propulsion speed of the propulsion cylinder are very difficult to coordinate, when the drill pipe is unloaded, the propulsion mechanism can only be kept stationary, and the rotation of the slewing mechanism can help It is used for drilling fan-shaped holes in underground mining tunnels. Swivel, propulsion mechanism and rotating rod The slewing mechanism is driven by a low-speed high-torque hydraulic motor that drives the drill rod, impactor, and drill bit to rotate for rock drilling operations. The compressed air used by the impactor is supplied from outside.China Drill Pipes website:http://www.jsdrilltools.com/drill-pipes/
