Revata Engineering's Rotating Centralizer can be used with a Rotating Liner in highly deviated well condition. These Centralizers have high Restoring Force, which provides optimum Stand Off and Low moving force to minimize drag. They meet or exceed API 10D specification. The Centralizer allows free rotation of pipe for maximum displacement efficiency. The Stop Collar between the End Collar minimizes moving forces while reciprocating.
Rotating Bows are made of special Double Rolled Alloy Steel and hot formed in totally controlled Heart Treatment Plant to achieve the uniform hardness all over and good spring action. End Collars are specially designed with roll formed peripheral ridges, which provide extra rigidity. Slips On Centralizers are provided for direct installation on pipe by slipping on to casing pipe.
Rotating Bow Spring strongly welded to the End Collar under required temperature and condition with extra low Hydrogen coated Electrodes. This assured ultimate strength and uniformity in every weld. A stop Collar placed inside the End Collar.
They are shipped in assembled condition only.
These centralizers undergo a special Iron Phosphate coating process to prevent from Rust then coated with special Polyester Powder they are available in sizes ranging from 4 ½“ to 13 3/8”.
