is one of the most common consumables in drilling operations and a critical component of the drilling rig. Its performance significantly impacts the progress of drilling projects. they are typically made from specialized alloy steel tubes for geological applications, with tool joints friction-welded to the pipe body. This construction provides good directional stability and high compressive strength, making them suitable for conventional exploration and coalbed methane drainage. Therefore, proper use and maintenance is an essential skill for any qualified drilling rig operator. Here are some key precautions to consider when using drill pipe:
During air drilling or pressure testing, verify that all pipe connections are secure. For drilling pipes with sealing elements, such as O-rings, regularly inspect their condition and replace them immediately if damaged or corroded. Clean and maintain sealing elements after completing drilling operations.
When making up its connections, first hand-tighten to ensure proper thread engagement. Do not use the rig to make up connections directly, as this can lead to cross-threading and thread damage.
(10) Store Drill pipes in a dry location with proper support at the bottom end. Perform regular maintenance for long-term storage.
(11) Avoid stacking heavy objects on drilling pipes or using them as supports. Do not store them haphazardly under piles of sand, gravel, or other materials.
(12) After cleaning and maintaining drilling pipes, apply thread compound and install thread protectors for storage to ensure stable performance.
