Slant Tube Watertube

Slant tubes provide dependability, quiet operation and long life. Inclined tubes provide uniform heat transfer, resulting in high fuel economy and long boiler life. 2″ O.D. tubes (steel or copper) are rolled into large headers on both ends producing excellent boiler circulation. 2″ O.D. tubes are less restrictive than smaller O.D. tubes. Our non-proprietary tubes are less costly for tube replacement. Straight tube design allows for easy inspection of tube conditions.
