Abstract
A pipe scraper assembly is forced through condenser pipe interiors for scraping residue off the inner wall surface. The scraper assembly is formed with a cylindrical body with a head and a tail end. Several mutually spaced apart rings are coaxially and rotatably supported on the cylindrical body between the head and the tail end. The diameter of the rings corresponds to the inner diameter of the pipe to be scraped. The rings have a radial cut formed therein which extends obliquely relative to the longitudinal axis of the cylindrical body.
Claims6
A pipe scraper assembly for scraping pipe interiors with a given inner diameter, the pipe scraper comprising:
- a substantially cylindrical body with a head and a tail end, a plurality of mutually spaced apart rings coaxially and rotatably supported on said cylindrical body between said head and said tail end;
- said rings having a diameter substantially corresponding to a given inner diameter of the pipe to be scraped;
- and
- each of said rings having a radial compression slot formed entirely therethrough in the radial direction extending obliquely relative to a longitudinal axis of said cylindrical body.
