Reliance Water Columns

All Reliance water columns and components are designed and manufactured in total compliance with ASME Boiler Code requirements. Of special importance, all steel water columns are welded according to specific qualified procedures that meet ASME requirements.  Water columns and components such as gage glasses and valves are hydrostatically tested to 150% of their design pressure. Today, Reliance continues as the foremost name in water column technology and manufacturing.  Our current advanced boiler trim products are modern-day versions of their predecessors that were pioneered by the Reliance Gauge Column Co.  We are America’s oldest and most respected exclusive boiler trim manufacturer.
