Matters needing attention in the use of drill pipe

When using for the first drilling, it is necessary to "grind the new buckle" first, which includes the technological innovation of applying screw thread oil first, then using the drilling machine to tighten the buckle with full strength, opening the buckle for domestic demand, applying screw thread oil and opening it again, and repeating this for three times to avoid new wear and buckle. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid the thread part side force and cause unnecessary wear and extremely low, or even jump buckle drill pipe, pay attention to the rig anchor to avoid the construction of the force movement is very important. When using a new drill pipe, it should be determined that the screw thread of the front section of the drill bit (protecting the shaft head) is also close to the turning head of the new bad buckle.

When using a new drill pipe, it should be determined that the screw thread of the front section of the drill bit (protecting the shaft head) is also close to the new one. The turning head with a bad button can easily damage the screw thread of the new drill pipe, resulting in water leakage, buckling, loosening, etc.
