1.Introduction：
The loss of the drive pipe wear in the drill pipe joints can’t be ignored during the processing of the deep mine, ultra-deep well, horizontal well and directional well. Using casing abrasion can effectively reduce the wear of drill pipe joints and lower the friction torque during the time of the drill pipe rotate. The both ends of the casing abrasion is conventional drill buckle, it can be easily individual or assembly used according to the requirement of well drilling.
2.Casing antichafe machine characteristics
.Adopting cemented carbide bearing, drilling fluid lubrication, long life, low friction coefficient.
.Made by high strength alloy steels, high strength, safe and reliable.
.Outside sliding sleeve is used low hardness alloy and antifriction composite.
