Importance of rod Dope for HDD Drill Rods

1.Reduces in-hole vibration that can cause the HDD drill rod to crack

2.Protects the metal surfaces of thread and provides an adequate seal to prevent leaks

3.Prevents galling by protecting the mating metal surfaces. A good quality thread compound will have some percentage of soft metal such as zinc, lead or copper。

4.Prevents the belling of HDD drill rods which occurs due to excess torque, excess tightening or excess vibration in a dry borehole

5. Increases the HDD drill rods resistance to rust and corrosion as they are water repellant and therefore not washed out by water
