  When purchasing Shank Adapter and drill rods for mining, you should pay attention to the following aspects: strength, that is, the relationship between pipe diameter, wall thickness and steel grade; torsional stiffness becomes more important in a longer drilling time to avoid The drill pipe is tangled. Connection size and type; outer and inner diameter of the underground hydraulic system; strength and applicability. The details to note are:

  1. For the strength of Shank Adapter, confirm that the contractor uses S-grade drill pipe with high strength and toughness. The new steel mixture can be heat treated, and the drill pipe is harder than in previous years. Other grades of steel are mainly used in other applications, such as Grade G for oil and gas drilling.
  2. For the connection of Shank Adapter, transmission contractors prefer to use tested universal connections, which are provided in standard form or shoulder function. The shoulder form provides a second shoulder at the end of the pin, thereby increasing the strength of the connection by approximately 30% and encountering slip torque downhole, which helps prevent excessive torque in the connection.

  Other connections can be used, but will encounter a series of problems, such as alignment problems, maintainability of re-cutting, and availability of cross joints, adapters or accessories. Compared with downhole hydraulic systems, for longer holes, connection becomes an issue. When traversing rocks, the hard strip can prolong the service life of the drill pipe.

  1. The value of Shank Adapter. When determining the value of used drill pipe, the important factor is the available space. If it is placed in a traditional area and cannot be fixed with a drill, some space may be lost due to hard lashing. When buying second-hand drill pipes when measuring pins and cassette tool joints, some drill pipes may not have enough space to use together.
  2. The quality of Shank Adapter, the quality control standards of Shank Adapter for mining and the quality of steel sources should obtain strict standards from manufacturers and/or processors. The quality of tool joints will help prevent bending and rotation fatigue and avoid downhole malfunction.
