Precautions for connection of triangular drill pipe The triangular drill pipe is a steel pipe with a thread at the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the drilling. The purpose of the triangular drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. The triangular drill rod must be able to withstand large torques, twists, bends and vibrations during rotation. During the drilling process, the three-pronged drill pipe can be used multiple times. Precautions for connection of triangular drill pipe (1) The connecting bolts of each part must be tightened to avoid loosening and falling into the triangular drill pipe to cause the rod to be stuck. (2) Quality of heavy-duty joint ring and wire rope card

(1) The connecting bolts of all parts must be tightened to avoid loosening and falling into the triangular drill pipe to cause the rod to be stuck.
(2) The quality of heavy-duty joint ring and wire rope clamping shall be reliable, so as to avoid the clamping of broken fragments into the triangular drill pipe.

What are the cleaning and maintenance precautions for triangular drill pipe joints? Let's take a look at the following:
12. Disassembly and cleaning of hydraulic parts shall be carried out in a clean room in accordance with national standards. If conditions permit, it is recommended that the operation room can be pressurized to make the indoor pressure higher than the outdoor pressure to prevent atmospheric dust pollution. If the conditions are limited, the operating room should also be isolated separately. Generally, hydraulic parts assembly room and machining room or fitter room are not allowed to be in the same room. It is absolutely forbidden to decompose and assemble hydraulic parts in the open air, shed, utility room or warehouse. When disassembling and assembling hydraulic parts, the operator should wear work clothes and work caps with fibers that are not easy to fall off to prevent fibers, dust, hair, dander, etc. from falling into the hydraulic system and causing man-made pollution. Smoking and eating are strictly prohibited in the operating room.
2Hydraulic parts cleaning should be carried out on the special cleaning table, if limited by conditions, but also to ensure the cleanliness of the temporary workbench.
33. Kerosene, gasoline and hydraulic oil with the same oil grade as the hydraulic system are allowed to be used for cleaning fluid of triangular drill pipe.
4The cleaned parts are not allowed to be wiped with cotton, hemp, silk and chemical fiber fabrics to prevent the shedding of fibers from polluting the system. If necessary, clean and dry compressed air can be used to dry the components.
53. The cleaned components of the triangular drill pipe are not allowed to be directly placed on the ground, concrete floor, floor, bench and assembly workbench, but should be placed in a container with a lid and injected with clean hydraulic oil.
63. The components that have been cleaned but not assembled for the time being shall be stored in anti-rust oil, and anti-rust shall be paid special attention to in humid areas and seasons.

Triangular drill rod generally has two kinds of driving mode, one is the top drive, the other is the rotary table rotation. Top drive: There is a moving pulley and a big hook under the top of the crown block. The big hook hooks the top drive device. There is a motor inside, which drives the square triangular drill rod and drill bit by electric shock. This method still requires a turntable, mainly for fishing with a triangular drill pipe in an extended pipe. May not turn. In another type, the square triangular drill rod is inserted into the rotary table, and the rotary table rotates to drive the square triangular drill rod and the drill bit to rotate.
