___
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.
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.
