(800) Mr. Winch greg@ryanhyd.com www.ryanhyd.com What is Galling? When referring to rod threads, galling is a form of adhesive thread wear which occurs between two sliding surfaces. Sometimes referred to as cold welding, it happens when two meeting surfaces are under extreme pressure. High torque or loading without the proper thread compound can cause galling of drilling rod threads. It can also occur when there is dirt and dust on the threads; when the wrong kind of thread lubricant is used; or when not enough of it is used. 44% of the U.S. population depends on groundwater for its drinking water supply.
