The Hartford Loop connects to the equalizer with a close nipple because steam rises up through the equalizer, just as it does through the boiler sections. When the relatively cool return water meets that steam at the close nipple, the rising steam bubbles quickly condense.

A steam boiler's condensate return piping is connected to the piping that directly connects the boiler outlet pipe to the boiler's water return connection above the boiler's water level to reduce water level fluctuations in the boiler.

line that carries condensate back to the boiler. Equalizer— Piping from top of boiler to maintain pressure balance on water in boiler return connection. Flash Steam— Reevaporation of condensate back into steam. It occurs when condensate flows into a reduced pressure area where the condensate's temperature is above boiling point for
Every Steam Boiler Manufacturer in his "Installation Instructions" Manual details a boiler piping configuration known as "The Hartford Loop" and Equalizer Piping, whether socalled or not. Named after the Hartford Insurance Company that funded its development, it tames the modern steamers by preventing the overheated, split and
What are Hartford loops and equalizer pipes? Share it! Get more answers from the people in your networks. Tags . Building Supplies, helped prevent water from backing out of the boiler by ensuring that the steam put equal pressure on the supply and return side of the boiler. The equalizer pipe looks like a short circuit between the supply

(2) All supply and return sizes are based on a 20°F temperature 6rises through the boiler. (3) Gauge24" minimum from water line to header. Model
Equalizer Sizing There is a good discussion on Equalizer sizing on page 6364 in "The Lost Art of Steam Heating". If you have water from the header entering the equalizer in "slugs" your boiler water line is going to be really dancing up and down.
The steam's velocity can create a pressure drop in the equalizer that will lift the water up, causing a corresponding drop in the boiler's water line. In 1919, the Hartford Steam Boiler Insurance and Inspection Company invented the Hartford Loop .

During operation the pressure at the supply and return openings to the steam boiler must be equal, this is why you install the "equalizer" piping. Improper piping and cleaning of a steam boiler also leads to noisy banging (water hammer) in the system pipes.

The Hartford Loop on Steam Boilers Definition, function, safety features, piping for the Hartford Loop to bring the return directly back into the bottom of the boiler without the benefit of either a Hartford Loop or an equalizer. When they piped a boiler this way, however, the slightest steam pressure would push water out of the boiler and
The steam's velocity can create a pressure drop in the equalizer that will lift the water up, causing a corresponding drop in the boiler's water line. In 1919, the Hartford Steam Boiler Insurance and Inspection Company invented the Hartford Loop .

The steam boiler sight glass or water level gauge allows the building owner or maintenance person to monitor the required water level in the steam boiler. A mark on the boiler body indies the desired normal water level and a sight glass shows the current water level.
High Pressure Steam Boiler Equalization. Darrell Lackey Posts: 6 Member. July 2006 in THE MAIN WALL. In a high pressure (125 psig) steam boiler plant of five 250 hp boilers connected to a common header designed for four operating when load is at maximum with one standby, each boiler has ASME outlet piping with nonreturn and shutoff valves.
