【Summary Description】 In the geological exploration work, the role of the drill pipe and the joint of the geological exploration can not be underestimated, through which special operations such as applying weight on bit, transmitting power, transporting drilling fluid, squeezing cement, and dealing with downhole accidents can be carried out. However, the material requirements for drill pipes and joints are higher, because ordinary drill pipes and joints are generally not able to withstand the pressure brought by drilling.

In the geological exploration work, the role of the drill pipe and the joint of the geological exploration can not be underestimated, through which special operations such as applying weight on bit, transmitting power, transporting drilling fluid, squeezing cement, and dealing with downhole accidents can be carried out. However, the material requirements for drill pipes and joints are higher, because ordinary drill pipes and joints are generally not able to withstand the pressure brought by drilling.
The steel materials selected for drill pipes and joints produced by Weilida are all selected from large enterprises such as Baosteel. They are not easy to fatigue bend and break, and have stable and reliable performance. The rod body is made of geological special alloy steel pipes R780 and DZ60. The drill pipe joints are made of high-quality alloy structural steel (42CrMo). After vacuum heat treatment and nitriding treatment, the fatigue strength and wear resistance are greatly improved.

Although ordinary materials or low-priced drill pipes and joints will reduce the initial investment of the construction party, the high-quality drill pipes and joints produced by Weilida with advanced equipment and 30 years of experience have a long service life and a low damage rate, which can give you long-term benefits.

Proper maintenance of drill pipes and joints during exploration, effectively reducing unnecessary damage and saving frequent replacement expenses, becomes very important.
Weida is here to send you the following suggestions, hoping to help you
1. The first tightening of the new drill pipe joint and the first several times of drilling are the key to prolong the service life of the joint. When the new joint is used for the first time, attention must be paid to avoid forcible fastening when the screw pattern is not aligned. When buckling, the crest of the new thread will sometimes resist each other. It should be slightly reversed and buckled after the thread is not top. Fasten it slowly, then tighten it with a sling.
2. The threads and shoulders of male and female joints must be thoroughly wiped clean before connection. After cleaning, be sure to dry the thread to ensure that the thread oil can be well attached to the thread surface.
3. When the drill pipe is moving and on the drilling frame, wear a wire guard cap to prevent the drill pipe joint thread from being damaged. Place unused drill pipe and drill pipe joints, and tighten the clean drill pipe thread guard cap with your hand, which is of great benefit to the protection of shoulder and thread.
4. The drill pipe joint is subject to huge torque during work. If there is no oil film separating between the joint threads, the threads will wear and buckle under huge torque. Threaded oil can play the role of this oil film.




Weilida's warm reminder: Please do not make the thread oil too thin for the convenience of application, because the diluted thread oil will reduce the effect of filling metal materials, thus causing the thread oil to fail.
