1, In the use of new drill pipe, it should be determined before the drill bit (protect the shaft head) is also close to the new buckle of the rotor can easily damage the new drill pipe threaded, causing leakage, buckle, loose Off state.
2, in the use of drill pipe for the first drilling, you should first "grinding new buckle," which includes, first smear thread oil, and then fully tighten the drill, and then open the buckle, and then wipe the threaded Open the oil again, so repeated three times, to avoid the new wear and buckle.
3, as far as possible to maintain the drill pipe under the ground with the ground on a straight line, so you can avoid the threaded part of the side of the force and cause unwanted wear and tear, or even jump buckle, pay attention to the rig anchor to avoid forced movement during construction is very important of.
4, the buckle should be tightened slowly, reducing overheating wear.
5, Each time the buckle must be tightened with full torque, and always pay attention to the clip state is good.
6, shorten the drilling machine into the mouth of the distance, because if the lack of support drill pipe, drill pipe will be easy to guide the deformation of bending, resulting in reduced life expectancy.
7, keep the entrance angle as small as possible, slowly change the angle according to drill pipe safety requirements.
8, Do not exceed the maximum bending radius of the drill pipe, with special attention to change into a horizontal section when drilling and change into a drilled angle when drilling.
9, to keep the use of drill pipe, to avoid the fixed drill pipe to fight and back to expand, we must take turns to avoid excessive wear and broken rod.
