Sell Hastelloy Heat Exchangers From Water and Wastewater Facilities

Hastelloy Heat Exchangers in Water and Wastewater

Hastelloy heat exchangers are specialized thermal management units constructed from nickel-molybdenum-chromium alloys, such as Hastelloy C-276, C-22, B-2, and Hastelloy-N. These high-performance alloys are selected for their exceptional resistance to general corrosion, stress corrosion cracking, and high-temperature degradation in aggressive chemical environments. In a water or wastewater facility, the documented process context matters: In the water and wastewater industry, heat exchangers are primarily utilized for energy recovery and maintaining optimal temperatures in processes such as anaerobic digestion and sludge treatment. These facilities often employ various types of heat exchangers, including spiral, tube-in-shell, and plate designs, to transfer heat from treated wastewater or biogas systems to incoming processes.

This page combines the approved hastelloy heat exchangers identification record with the approved water and wastewater process record. It does not infer condition, suitability, ownership, or value from an industry label alone.

Identification and documentation checklist

A seller should connect the physical unit to its service and records before requesting evaluation. For this intersection, document both the asset construction and its actual water and wastewater duty.

• Verify material of construction as Hastelloy (e.g., C-276, B-2, C-22, or N) via original manufacturer data reports.
• Check for ASME Boiler and Pressure Vessel Code stamps and U-1 data reports.
• Identify heat exchanger type (e.g., shell and tube, printed circuit).
• Inspect for potential phosphate scale or corrosion products if used in acidic or molten salt service.
• Maintenance logs showing chemical descaling history.
• Records of struvite and vivianite removal.

Condition and value factors

Hastelloy heat exchangers are designed for high-temperature and highly corrosive environments, often utilizing alloys such as C-276, C-22, or Hastelloy-N. That technical characteristic is only one input; current condition, completeness, documentation, demand fit, installed scope, and logistics also influence review.

Heat exchangers from wastewater treatment facilities may show heavy scaling and fouling. Service history and residual-process disclosure should therefore be evaluated with the equipment record rather than treated as an automatic positive or negative value conclusion.

• Current photographs and readable nameplate
• Dimensions, weight, quantity, and installation state
• Known metallurgy and service fluid
• Inspection, cleaning, repair, and operating history
• Seller authority and intended disposition timing

Commercial review boundary

Submission requests a fact-based buying review. It does not guarantee purchase, price, payment timing, removal, loading, freight, or reuse. Those terms require separate written confirmation after the equipment and project facts are reviewed.
