Alkaserts Industrial Grade PolyethyleneTube Inserts Conco Alkaserts are inert highly resistant to abrasion and erosion and are unaffected by chemical treatment programs. They are dimensionally stable to 75 C 170 F well above normal operating temperatures of steam condensers and have a negligible effect on heat transfer. While their feathered edge design allows for the smooth flow of cooling water into the tubes their minimum wall thickness and tapered design promotes maximum flow. Flexible enough to accommodate normal variations in tube bores yet rigid enough for easy installation these rugged inserts are designed to make a snug fit in the tube. Once in place there is no danger of water seeping between the insert and tube preventing crevice corrosion.
