ASME Bladder Type Expansion Tanks
Expansion tanks are designed to absorb the expansion forces of a heating or cooling system to maintain the proper system pressurization. In contrast from diaphragm tanks, bladder tanks completely enclose the water inside a replaceable butyl rubber bladder (other bladder materials available upon request), eliminating problems such as water-logging and tank corrosion. Air precharge pressure is maintained using a car-tire type valve, also known as a Schrader valve.
Similar to other items in a heating or cooling system, bladder tanks must be maintained to ensure proper operation. Precharge pressure must be field adjusted per the operating conditions of the system it is being installed in. See IOM for more details regarding proper maintenance procedures.
