DESIGN OF SHELL AND TUBE HEAT EXCHANGER - EPCM
Introduction to Design of Shell and Tube Heat Exchanger
Shell and Tube Exchangers-Dallas, Texas-Thermal Transfer Custom shell and tube heat exchanger can have 3 or 4 main components depending on the style:an inlet head, tube bundle, shell, and an outlet head. To go into more detail the TEMA designations of shell and tube heat exchanger can be viewed here.
Heat Exchanger tubes Tubing that is generally used in TEMA sizes is made from low carbon steel, copper, Admiralty, Copper-Nickel, stainless steel, Hastalloy, Inconel, titanium and a few others. It is common to use tubing from 5/8" to 1-1/2" in these designs. Tubes are either generally drawn and seamless or welded.
Shell and Tube Heat Exchanger:What Is It? Types, ProcessTubes of a shell and tube heat exchanger are welded or extruded and made from carbon steel, stainless steel, titanium, Inconel, or copper. Tube diameters of 0.625 inch (16mm), 0.75 inch (19mm), or one inch (25mm) are used in compact heat exchangers.
Also known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. Theyre commonly used in refrigeration and engine cooling systems. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.
Six Causes of Heat Exchanger Tube Failure
Tube Corrosion. The biggest threat to shell and tube heat exchangers that use carbon steel tubes
Similar, but in less degree, phenomena occurs in shell & tube heat exchangersfor water heating. Indeed, copper tubes are oxidized, resulting in fast accumulation of solid deposits. Copper has poor mechanical properties, particularly on elevated temperatures common in heat transfer.
SX2000 - steel shell/copper tubes - Heat ExchangersMaterials:Carbon steel shell and tube-sheets with cast-iron bonnets and copper tubes are standard. Additional materials are available for tubes and tubesheets. Applications:To cool lube oil, fluids or jacket water, and for use where brass is not practical. Application:Straight tube fixed tubesheet, shell and tube heat exchanger.
