Sanitary Standards for Tubular Heat Exchangers
standard by 3-A Sanitary Standards, 06/04/2021
Full Description
These standards cover the sanitary aspects of tubular heat exchangers without agitators. Tubular heat exchangers may have tube cross-sectional profile modifications or removable devices for promotion of desired flow characteristics. The standards do not cover high-pressure (greater than 250 psig or 1724 kPa product pressure) tubular heat exchangers which require special tubing and/or fittings.
In order to conform to these 3-A Sanitary Standards, tubular heat exchangers shall conform to the following design, material, and fabrication criteria.
