Oakville, ON -- (SBWIRE) -- 05/22/2017 -- At Advanced Industrial Components (AIC), they are often asked by their clients: "What heat exchanger type should I use - plate or tubular?" The answer is… it depends on their application. Here they will take a quick look at a few variables to consider the next time someone is in the market for a heat exchanger.
Fluid Flow and Pressure Drops: A tubular type of heat exchanger (removable u-tube, straight tube, or welded shell & tube design) will generally allow for larger amounts of fluid through the unit with relatively lower pressure drops than when compared to a plate exchanger (brazed plate or plate & frame), whose dense plate packs acts as a restriction barrier.
Heat Transfer Area: Due to the thin plates and chevron designs of their tight plate packs, plate heat exchangers have a high heat transfer rate to surface area ratio, meaning that these exchangers may be more favourable for applications with lower temperature differentials or when a close temperature approach is required. For plate & frame heat exchangers, if the frame allows for it, additional plates may be added on to an existing unit, on site, to increase the heating surface area.
Hardiness: Industries such as oil & gas prefer the use of tubular heat exchangers for the ruggedness and flexibility of the design. Thick tubes and shells. Use of expansion joints. Resilience with different fluid types - viscous oils, steam, etc. There is wider scope in tubular designs than compared to plate designs, enabling more customization of the product to suit a client's particular needs.
Maintenance: Both plate and tubular designs carry products that are either 'removable' or 'welded/brazed'. Plate packs in plate & frame exchangers may be removed, cleansed, and/or replaced. Tube bundles in u-tube or straight tube heat exchangers may be removed, cleansed, and/or replaced. One may argue that it is a more arduous task in one design than the other; however, that is up to the client to determine.
Certifications: If required, both plate and tubular heat exchangers may be designed to the ASME Code. Tubular exchangers may also be governed by TEMA standards.
