Review(0)

The casing scraper is used to remove foreign matter on the inside casing wall in order to provide a smooth clean casing I.D. for running sub-surface equipment. The casing scraper features a one piece body with full 360 degree casing I..D. coverage provided by spring loaded Scraper Blades. The design also features a large by-pass area around and between the blades for ease of circulating. Each blade is secured in it’s own individual pocket and ensures that all thrust and rotational forces are absorbed directly by the one piece body. No special tools other than a Pipe Vise are required to change the blades or springs. The casing Scraper features leaf type Springs behind each self-sharpening blade, providing maximum usage before repairs or replacement is necessary. API regular pin up and box down are normally supplied with the Casing Scraper, with other connections available if required.

•Operation

•The Casing Scraper may be run on tubing or drill pipe and operated equally well when reciprocated vertically or when rotated. Normally rotation is not necessary unless restrictions are encountered. In areas where other tools are to be set, the scraper should be reciprocated through a number of times to ensure the casing is clean and smooth.

•Available in sizes from 4 1/2" to 20"
