Triangular drill pipe and matching should choose a manufacturer to ensure uniform standards and achieve the best matching.
On-site useMatters needing attention
(12) During the relocation of the three-pronged drill pipe, the drill pipe shall be handled gently and not thrown.
(22) During the process of removing the screw thread, do not use the sledgehammer to strike hard.
(31) If the wear is found to be out of tolerance, it shall be replaced immediately.
(43) The triangular drill pipe has a service life. If it exceeds the service life, it should be replaced as a whole.
(52) Avoid mixing the discarded three-pronged drill pipe with the new three-pronged drill pipe.
(62) Avoid mixed use of trigonal drill pipes of different standards.

Tips for Reducing Wear of Triangular Drill String
1High-strength materials should be used in the research and development of high-quality materials for triangular drill pipes, and lightweight aluminum alloy and other materials should be selected as triangular drill pipe materials. Improve the processing technology and do a good job in heat treatment to make the internal structure of triangular drill pipes more refined and perfect.
2If the verticality of the drilling is high, the contact surface between the triangular drill string and the hole wall will be reduced accordingly, and the rotation around the axis will be increased, thus reducing the friction between the triangular drill string and the hole wall.
3Use solid-free drilling fluid to reduce the viscosity and density of drilling fluid to reduce the erosion and wear of the triangular drill string;PHvalue, inhibit the corrosion of acid gas on the triangular drill string, and use oxygen scavenger to reduce the oxidation corrosion of the triangular drill string.
