Self Centralizing Casing Scraper

Field Marshall Self Centralizing Casing Scraper

Size range availability: – 5” to 13-3/8”

The self-centralizing casing brush is a high performance well clean-out tool designed to scrape the interior walls of casing, removing deposits of scale, cement and other debris prior to completion.

The built in rotating stabilizers perform two functions;

  • Centralize the brush pads during operation ensuring the brush pads exert equal pressure against the riser walls
  • Reduce torque when operating in high angle or horizontal risers.

The brush pads which cover 360 degrees are designed to operate under pressure by way of springs located below, as the brush pads wear in use the pressure below the pad allows for consistent wear and even cleaning.
AISI 4145 Mod steel is used for the one piece tool body and stabilizers. The brush pads and bristles can be manufactured in various materials as required.
