Armstrong Heat Exchangers Shell and Tube | Boiler Supplies

Additional Information

Armstrong shell and tube heat exchangers are built with precision-engineered components designed for efficient, long-term thermal performance. The shell is typically fabricated from carbon steel pipe or rolled plate for cost efficiency and fast lead times, with alloy options available for high-temperature or corrosive applications. Maintaining shell roundness ensures tight baffle clearances, improved heat transfer, and reduced vibration, while impingement plates protect against erosion at high-velocity inlet nozzles.

 

Heat exchanger tubes are available in materials such as carbon steel, copper alloys, stainless steel, and high-performance alloys, with standard diameters ranging from 5/8" to 1-1/2". Tube configurations include straight-tube and U-tube designs to accommodate thermal expansion, with optional surface enhancements to increase heat transfer efficiency.

 

Bonnets and end channels direct tube-side flow and support multi-pass designs, maintaining consistent velocity and pressure drop. Precision-fit baffles support the tube bundle, prevent vibration, and force shell-side fluid across the tubes for maximum heat transfer. Baffle spacing and cut percentages are carefully engineered to balance performance and pressure drop for both liquid and gas applications.

In-stock orders eligible for small-pack shipments placed before 2:00 PM EST, Monday through Friday, will ship the same day. If ordered after 2:00PM EST, it will ship the following business day.
