Alkaserts - Polyethylene Tube Inserts Brochure

Conco Alkaserts® are widely used in electric power stations, industrial power plants and on ships – wherever inlet end tube erosion and impingement present a problem.  They are designed to assure lasting protection to the inlet ends of new tubes and greatly prolong the life of worn tubes damaged by erosion or impingement.  Alkaserts® are inert and highly resistant to erosion and abrasion.  They are dimensionally stable well above normal operating temperatures of steam condensers.  Alkaserts® are flexible enough to accommodate normal variations in tube bores, yet rigid enough for easy insertion.  They are designed to make a snug fit in the tube so that there is no danger of water seeping between the insert and tube.
