8/23 · where: h1 and h2 are the partial heat transfer coefficients, W/m 2. o K (tube and shell side) Rw is the thermal resistance of the wall, m 2. o K /W Rf1 and Rf2 are the fouling factors, m 2. o K /W (tube and shell side) While the values for Rf are usually specified by the client, the values of h and Rw can be influenced directly by the designer depending on the choice of tube size

Here shell and tube type heat exchanger has been selected due to its flexibility of design, which allows wide range of pressures and temperatures. Standards laid out in ASME BPE for selection of

The 316l Stainless Steel Heat Exchanger is stronger and corrosion resistant than the 316 Stainless Steel Heat Exchanger but is less tough due to the lower carbon content. The 304 Stainless Steel Heat Exchanger is stronger but is less

Heat Exchangers for Hot Acids: Material Selection To make the modern materials we use every day, such as plastics, metals, electronics, 

Good Practice For Heat Exchanger Selection And Design Page 4 of 12 • Use one tube pass per shell (Pure counter current). • Use shells in series. • Use F, two pass shell. (Two exchangers in series can be modeled in one shell.) • Double pipe or hair

A shell and tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes

2.7.1 The exchanger effective surface is the outside tube surface measured between the inner faces of the tubesheets. For U-tube bundles the exposed U-bend portion is admissible, provided the shell nozzle is located past the U-bend tangent point and the velocity of the following fluid makes this surface e

5/20 · The heat exchanger designer would also identify the tube attachment method as this also affects the material selection is being done by someone other than the heat exchange designer, there must be close consultation between these individuals.

The heat exchanger is made of acrylic material with 2 baffles and 7 tubes made of stainless steel. Hot fluid flows inside the tube and cold 

For one of our AES type heat exchanger, we noticed leakage in the tubes so please advise me which material is suitable for highly corrosive 

i) Straight Tube, Fixed tubesheet, Type BEM, AEM, NEN, Etc. This TEMA type is the simplest design and is constructed without packed or gasketed joints on the shell side. The tubesheet is welded to the shell and the heads are bolted to the tubesheet. On the NEN heat exchanger, the shell and the head is welded to the tubesheet.

Any component or the entire unit can be made of materials such as carbon steel, stainless steel, nickel, nickel alloys or other special alloys. Selection of materials involves careful evaluation of factors other than the basic cost of possible metals compatible with the application. CMS Heat Transfer Division, Inc.
