Importance of Pipe Coating for Drill Pipe
1. Reduce in-hole vibration that may cause drill pipe cracking
2. Protect the metal surface of the thread and provide sufficient sealing to prevent leakage
3. Prevent wear by protecting the mating metal surface. High-quality thread compounds will contain a certain proportion of soft metals, such as zinc, lead or copper.
4. Prevent drill pipe ringing in dry drilling due to excessive torque, excessive tightening or excessive vibration
5. Increased the anti-rust and anti-corrosion ability of the drill pipe, because they are waterproof, so they will not be washed away by water
