Product Description

 

Description:
Advanced thermal spraying technology is adopted to melt Ni alloy and other high wear-resisting materials on the blank surface of the collar after high temperature flame spraying, so as to reduce the friction coefficient between the anti-wear collar and the oil pipe to 0.01, which is an effective combination of high hardness and low friction, thus improving the service life of the rod and pipe in oil exploitation.

Features

 

Features:
1. Designed and manufactured according to API spec 11B.
2. The couplings are manufactured in grades SM and DES.
3. Increased wear and corrosion resistance.
