Basic Construction of Shell and Tube Heat Exchangers

Shell and tube heat exchangers represent the most widely used vehicle for the transfer of

heat in industrial process applications. They are frequently selected for such duties as:

. Process liquid or gas cooling

. Process or refrigerant vapor or steam condensing

. Process liquid, steam or refrigerant evaporation

. Process heat removal and preheating of feed water

. Thermal energy conservation efforts, heat recovery

. Compressor, turbine and engine cooling, oil and jacket water

. Hydraulic and lube oil cooling

. Many other industrial applications

Shell and tube heat exchangers have the ability to transfer large amounts of heat in relativelylow cost, servicable designs. They can provide large amounts of effective tube surface whileminimizing the requirements of floor space, liquid volume and weight. Shell and tube exchangersare available in a wide range of sizes. They have been used in industry for over150 years, so the thermal technologies and manufacturing methods are well defined andapplied by modern competitive manufacturers. Tube surfaces from standard to exotic metalswith plain or enhanced surface characteristics are widely available. They can help providethe least costly mechanical design for the flows, liquids and temperatures involved.

Shell and Tube heat exchanger:

1. Have obtained new-type invention patent 28 items, representative certificate of honor and patent

2. Suitable the anti-corrosive environment, Selects the anti-corrosive material

3. In January 2007, obtaining ASME “U" stamp certificate.

4. In December 2002, "a Rare Earth Alloy steel heat-exchanger" access to technology invention in Hubei Province "third prize”.

5. In May 2004, the "high temperature corrosion of sulfur-resistant air cooler in wet hydrogen sulfide stress corrosion and corrosion protection" was designated as the National Sparking Plan Project.

6. In November 2008 "rare earth alloy steel heat exchanger of heat transfer enhancement" was certified as national key new product.
