Pressure Vessel and Heating Surfaces
The water heater will be constructed and stamped in accordance with Section IV, Part HLW of the ASME code. The
water heater will be National Board Registered for a working pressure of 150 psi and will be pressure tested at 1-1/2
times working pressure. All tank connections will be nonferrous.
The heat exchanger will be a _____ single-wall or ____ double-wall (atmospherically vented), copper u-tube bundle
with nonferrous waterside tube sheet, baffles, and tie rods. Heat exchanger will be constructed to ASME code and rated
for 150 psi and 300°F service.
Tank Lining
The tank will be a plated with electroless nickel (EN). Plating will occur after the pressure vessel is completely
fabricated and all welding is completed. The EN plating will be a high-phosphorus (10%) and nonporous composition
suitable for submersion service (ASTM B733 standard may be used as a guideline). The finished lining will not require
sacrificial anode rods. For additional protection against galvanic corrosion, which may occur within the potable water
system, the electroless nickel plating may have a high-dielectric-strength polymer overcoat.
