Standard ASME Hot Water Storage Tanks

HLW Hot Water Tanks

HLW ASME code, Section IV applies to commercial- and industrial-sized hot water storage
tanks. The minimum nominal water capacity in these industrial and commercial hot water
tanks is 120 gallons (450 Liters). The maximum temperature is 210 ○F (99 ○C) and maximum
pressure is 160 psig (1100 kPa) for these potable hot water tanks.

Commercial Hot Water Tanks’ Usage

Vessels built under the HLW ASME code may be used for storage of potable water in several
different industries where a large quantity is required. The following businesses could benefit
from our hot water storage tanks: food processing, dairies, pharmaceutical, chemical
processing, hospitality, commercial laundries, hospitals, multi-dwelling apartment buildings, and many other industries.

Potable Hot Water Tanks’ Sizes

Hanson vertical standard sizes for potable hot water tanks are from 140 to 2150 gallons. The
horizontal standard sizes for hot water storage tanks range from 180 to 3500 gallons, with an
outside diameter ranging from 30 to 72 inches. The tanks are supported by angle legs or solar
feet. The standard lined potable hot water tanks are built with an 11 x 15-inch handhole in
order to access the inside of the tanks for the lining. This handhole is not required by the HLW ASME code. The minimum manway size is 12 x 16 inches. The smaller the surface, the less heat loss, so the larger the diameter of the hot water storage tank, the better.

Lining in Hot Water Storage Tanks

Hanson tanks are lined with gas, cement, or epoxy. A galvanized option is also available for
commercial hot water tanks. The protection the lining offers is necessary on the steel surface
because of a dissolved oxygen in the water works to corrode the tank and connections that can
lead to leakage.
