Spray Metal Polished Rod
Introduction
Spray metal polished rod has good mechanical properties and strong corrosion resistance. The surface coating is combined with the base material firmly.There is no peeling and cracking, which solves the problems of requirement of high strength and anti-corrosion performance.
The surface of spray metal polished rodhas a dense nickel alloy anti-corrosion layer after spray metal, has strong anti- wear and anti-corrosion properties, which can effectively avoid the coating peeling problem caused by friction between the rod and tubing.
