An ASME certified boiler is a closed vessel in which water is super heated. The super heated or vaporized fluid
exits the boiler for use in various processes or heating applications and is part of the Ameco USA products offered
in our metal fabricating line.
The Ameco manufatured pressure vessel in a ASME boiler is usually made of steel (or alloy steel), or historically of
wrought iron. Stainless steel is prohibited by ASME Boiler Codes for use in wetted parts of modern metal fabricating
boilers, but is used often in superheater sections that will not be exposed to liquid boiler water. In live steam
asme boilers, copper or brass is often used because it is more easily fabricated in smaller size boilers.
Historically, copper was often used for fireboxes (particularly for steam locomotives), because of its better
formability and higher thermal conductivity; however, in more recent times, the high price of copper often makes
this an uneconomic choice and cheaper substitutes (such as steel) are used instead.
Historically, asme boilers of metal fabricating design were a source of many serious injuries and property
destruction due to poorly understood asme engineering principles. Thin and brittle metal shells can rupture, while
poorly welded or riveted seams could open up, leading to a violent eruption of the pressurized steam.
ASME is one of the oldest standards-developing organizations in the world. It produces approximately 600 codes and
standards, covering many technical areas, such as boiler components, elevators, measurement of fluid flow in closed
conduits, cranes, hand tools, fasteners, and machine tools.
The largest ASME metal fabricating standard, both in size and in the number of volunteers involved in its
preparation, is the ASME Boiler and Pressure Vessel Code (BPVC). BPVC is a standard that provides rules for the
design, fabrication, and inspection of boilers and pressure vessels.
Most asme metal fabricated boilers now depend on mechanical draught equipment rather than natural draught. This is
because natural draught is subject to outside air conditions and temperature of flue gases leaving the furnace, as
well as the chimney design. All these factors make a proper asme metal fabrication draught hard to attain and
therefore make mechanical draught equipment much more economical.
The American Society of Mechanical Engineers (ASME) is a professional engineering concept, focused on mechanical
engineering. The ASME was founded in 1880 and its standards are incorporated by Ameco in all its metal fabricated
products. The organization is known for setting codes and standards for metal fabricating devices. The ASME conducts
one of the world's largest technical publishing operations through its ASME Press, holds numerous technical
conferences and hundreds of metal fabrication courses each year.
