There are three main types of connections for geological spiral drill pipes: threaded connection type, square connection type, and hexagonal connection type; among them, square connection is mainly hexagonal connection. Common tetragonal specifications: F24, F26, F30, F32, etc. Commonly used hexagonal specifications are: B34, B35, B41, B45, B55, etc., of which hexagonal specifications have taper hexagonal: B41-B42.5B48-B49. The geological spiral drill pipe is made by our company on the basis of the high torque performance of the geological drill pipe, using single spiral blades or double spiral blades, prestressed winding and fully automatic welding. The drill pipe body adopts high

There are three main types of connections for geological spiral drill pipes: threaded connection type, square connection type, and hexagonal connectiontype; where, in the square connection, the six-party connection is the main. Common Quartet Specifications: F24, F26, F30, F32The commonly used hexagonal specifications are: B34, B35, B41, B45, B55, etc., of which the hexagonal specifications have a taper of 6Fang: B41-B42.5 B48-B49.

The geological spiral drill pipe is based on the high torque performance of the geological drill pipe, using a single spiral blade.Or double spiral blades, prestressed winding, fully automatic welding. High-grade geological drilling is adopted for drill pipe bodySpecial alloy steel pipe, drill pipe joints using high-quality alloy structural steel, after high-pressure forming, vacuum conditioning treatment, friction.Wipe welding. It has the characteristics of high bending strength, firm welding and good slag discharge efficiency. Compared with similar products,The fatigue strength and shear strength are greatly improved.
