Brazed plate heat exchangers such as this on from Chart Heat Exchangers, LaCrosse, WI, are used in the production of petrochemicals and the treatment of off-gases.
The Brazed Aluminum Plate-Fin Heat Exchanger Manufacturers' Association (ALPEMA) has published the second edition of its standards.

The standards support the main objective of ALPEMA, which is to promote the safe use and quality of brazed aluminum heat exchangers. Topics addressed in the standards include materials of construction, design, manufacture, mechanical standards, installation, operation, contractual information and good practice.

Brazed aluminum heat exchangers are used in many applications, including cryogenic separation and liquefaction of air, natural gas processing and liquefaction, the production of petrochemicals and treatment of off-gases, and large refrigeration systems.

Copies of the standard can be obtained from ALPEMA members or directly from the association. The document also can be downloaded as a Adobe Acrobat (.pdf) file from the ALPEMA web site atwww.alpema.org.
