| titleOfInvention | A kind of anti-wear aluminium drill pipe |
| abstract | The utility model provides a kind of anti-wear aluminium drill pipe, wherein the aluminium alloy tube body both ends are equipped with upset end, upset end A is connect by screw thread with external screw thread steel connector, and upset end B is connect by screw thread with internal screw thread steel connector；There is intermediate thick section by extrusion forming on the aluminium alloy tube body, wear-resistant material layer is equipped between the intermediate thick section, the wear-resistant material layer is for smooth cylindrical type or with helicla flute cylindrical type；Advantage are as follows: the utility model aluminium alloy tube body in use is not contacted with external environment, improves safety and the service life of aluminium drill pipe；Wear-resistant material layer does not need mechanical fixing component, and drillng operation safety is effectively ensured；Wear-resistant material layer abrasion can repair original size, realize the reuse to the drilling rod long-life, the production cost of anti-wear aluminium drill pipe is effectively reduced；It realizes the lightweight of drilling machine, saves drilling cost. |
