Product Description Casing Scraper Product DescriptionA casing scraper is a downhole tool used to clean the inside diameter (ID) of casing or tubing. Its job is to remove scale, rust, cement sheath, perforation burrs, paraffin, mud buildup, or any other debris that may interfere with downhole operations. Clean casing ID ensures that tools such as packers, bridge plugs, sealing tools, wireline or logging tools can properly run, set, or seal. It helps avoid tool hang‐ups and improves operational reliability. Product ParametersSpecificationTypical / Example ValuesCasing Size RangeFrom about 4-1/2″ up to 20″ OD depending on model. Connection TypesREG / EUE / NC threads, box/pin; matching casing/tubing connections. Body Outside Diameter (Collapsed / Extended)For example: for 4-1/2″ casing, body OD approx 3.5-4.5″ when collapsed or extended; for larger casing, proportionally larger. Blade ArrangementMultiple spring-loaded blades, arranged in staggered blocks to give full 360° internal coverage. Blades often heat treated / hardened. Blade Expansion RangeBlade expansion beyond collapsed OD, typically several millimeters to "reach" into casing wall for scraping. (E.g. some models extend ~1″ or more beyond collapsed OD.) Body MaterialHigh strength alloy steel; springs and retaining hardware robust. Length / Overall Length / Gauge Hole SizeVaries with casing size; length sufficient to pass connections and provide stable scraping. Some tools have longer guide tapers to pass casing connections smoothly. Product AdvantagesEffective 360° Cleaning: Full circumferential blade coverage ensures debris and build-up is removed thoroughly, which improves tool running & sealing. Strong and Durable Design: Spring-loaded or rubber/sleeve mechanisms with positive retention, no loose fasteners; hardened blades resist wear. Reduced Inventory & Flexibility: Many designs cover wide casing size ranges due to blade extension and retraction; saves on needing many models. Smooth Passage Through Casing Joints/Collars: Tapered blade edges or long guide tapers help avoid snagging at casing collars or threads. Reliable in Harsh Environments: Robust body, high strength materials, ability to handle reciprocation + rotation in deviated / horizontal wells.
