2.3 MECHANICAL DESIGN REQUIREMENTS
A. General
1. The Plate Heat Exchanger Manufacturer shall not subcontract or purchase the plates for
resale. He shall press his own patterns of plates.
2. The Plate Heat Exchanger Manufacturer shall have an established and on-going
3. QA/QC program including manuals available for inspection at plant.
B. Frame Components
1. Preference will be given to single pass designs with all connections on the fixed cover.
2. The fixed and movable covers shall be of sufficient uniform thickness to withstand all
loadings. Welded reinforcements or stiffeners are not permitted.
3. The movable cover shall be provided with a roller bearing for units greater than 50" in
height. This allows the cover to be moved with greater ease during plate inspection.
4. The carrying and guide bars shall be designed to allow for a plate pack expansion of at
least 10% while still providing maintenance space.
5. The surfaces of the carrying and guide bars that come into contact with the plates shall be
stainless steel. All carbon steel frame components (except bolts) shall be painted or zinc
plated.
6. The heat exchanger frame shall be of bolted construction. Welding of the pressure
retaining components is not permitted.
