Specifications

1.A nonmetal abrasion-resistant sleeve
2.The O.D of protector is larger than that of a drill pipe collar

Function:

The Casing & Drill Pipe Protector is a nonmetal abrasion-resistant sleeve installed on a drill pipe by a position collar. The O.D of protector is larger than that of a drill pipe collar. The protector prevents the metal to metal friction between casing and drill pipes, thus achieving the purpose of casing and drill pipe protection. The protector consists of two positioning collars and a nonmetal abrasion-resistant sleeve.

 

Features:

1. The rated temperature reaches 180°C.

2. The abrasion resisting capacity is 500 times higher than that of cast iron.

3. The rotary drilling torque can be reduced up to 50%.
