Boiler Relief Valves An ASME Section IV certified pressure relief valve shall be installed on each boiler as noted. The valve shall have a BTU rating in excess of the BTU rating of the boiler's heating output. Each hot water space heating boiler shall be equipped with a pressure relief valve set to relieve below the maximum boiler working
(A) Each hot water heating boiler shall have at least one pressure relief valve, of the automatic reseating type, identified with the ASME Certification mark with the "V" or "HV" designator ASME Code Symbol, and set to relieve at or below the MAWP of the boiler.
Water: ASME Code Water Pressure Relief Valve are installed in the feed water line to guard against excess water pressure, frequently caused by failure to open the boiler feed water line valve. Please specify psi required Standard 1/2" npt $323.
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica

A storage water heater is one of the most commonly found items in a boiler inspector's working environment. However, not all water heaters will fall within the jurisdictional mandate requiring a periodic inspection. Most jurisdictions use the exemption criteria outlined in ASME BPV Code Section IV, paragraph HLW-101.2.

Re: Difference between ASME power boiler and Heating boiler 10/31/2013 10:08 PM There is those that can reurgitate definitions and dwelve on words and phrases and then there is engineers that understand associations and facts.
Perhaps the most widely accepted boiler and pressure code in the world is the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. This is an internationally recognized standard governing the design and construction of heating and power boilers and unfired pressure vessels.
The importance of installing the correct temperature and pressure relief valve on a water heater or hot-water storage tank cannot be overemphasized. This applies to new vessels as well as relief valve replacements. The importance of installing a valve with the correct pressure rating is common knowledge to many, but it also is crucial to install a valve with the appropriate relieving capacity
Series B-LA expansion tanks are ASME rated pre-charged bladder-type pressure vessels. The Series B-LA tank is designed to absorb the expansion forces of heating/cooling system water while maintaining proper system pressurization under varying operating conditions. The heavy duty bladder contains system water thereby eliminating tank corrosion and
5. All hot water heating or hot water supply boilers shall be constructed, inspected, stamped, and installed in conformity with Section IV of the ASME code. See OAC 4101:4-11-01 6.
