Product Description Descripition:shell and tube heat exchanger is a class of heat exchanger designs. 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 pressuere vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc. So,it is also called Tubular Heat Exchanger.Material: SUS304, SUS316L, Carbon Steel ,SMO254 and etc .Theory and Application:Two fluids, of different starting temperatures, flow through the heat exchanger. Oneflows through the tubes (the tube side) and the other flows outside the tubes butinside the shell (the shell side). Heat is transferred from one fluid to the other throughthe tube walls, either from tube side to shell side or vice versa. The fluids can beeither liquids or gases on either the shell or the tube side. In order to transfer heatefficiently, a large heat transfer area should be used, leading to the use of manytubes. In this way, waste heat can be put to use. This is an efficient way to conserveenergy.Shell and tube heat exchanger design:Counter current heat exchangers are most efficient because they allow thehighest log mean temperature difference between the hot and cold streams. Manycompanies however do not use single pass heat exchangers because they canbreak easily in addition to being more expensive to build. Often multiple heatexchangers can be used to simulate the counter current flow of a single largeexchanger.Applications and uses:1>.cooling of hydraulic fluid and oil in engines, transmissions and hydraulic powerpacks2>.heating other mediums,such as water,beverager,orange juice and other steam3>.they are extensively applied in chemical industrial,pertroleum and energy sourceand etc.The Heat Exchanger Tube Specifications Φ20DNQuantity of tube passQuantity of heat exchanger tubeQuantity of center raw tube tube pass flow area(m2)Heat exchanger area(m2)Tube length(mm)1500200030004500600015911550.0030 1.4 1.9 2.8 21913370.0066 3.1 4.1 6.2 27316590.0131 6.1 8.2 12.3 18.4 24.5 25680.0056 5.3 7.0 10.6 15.8 21.1 325199110.0199 9.3 12.4 18.7 28.0 37.3 288100.0088 8.3 11.1 16.6 24.9 33.2 468110.0034 6.4 8.5 12.8 19.2 25.6 4001174140.0350 16.4 21.9 32.8 49.2 65.8 2164150.0165 15.5 20.6 30.9 46.4 61.8 4146140.0073 13.8 18.3 27.5 41.3 55.0 4501237170.0477 22.3 29.8 44.7 67.0 89.3 2220160.0221 20.7 27.8 41.5 62.2 82.9 4200160.0101 18.8 25.1 37.7 56.5 75.4 5001275190.0553 34.6 51.8 77.8 103.7 2256180.0257 32.2 48.3 72.4 96.5 4222180.0112 27.9 41.8 62.8 83.7 The Heat Exchanger Tube Specifications Φ25DNQuantity of tube passQuantity of heat exchanger tubeQuantity of center raw tube tube pass flow area(m2)Heat exchanger area(m2)Tube length(mm)1500200030004500600015911130.0038 1.3 1.7 2.6 21912550.0087 2.9 3.9 5.6 27313860.0132 4.5 6.0 9.0 13.4 17.9 23270.0055 3.8 5.0 7.5 11.3 15.1 32515790.0197 6.7 9.0 13.4 20.1 26.9 25690.0097 6.6 8.8 13.2 19.8 26.4 44090.0035 4.7 6.3 9.4 14.1 18.8 400198120.0339 11.5 15.4 23.1 34.6 46.2 294110.0163 11.1 14.8 22.1 33.2 44.3 476110.0066 9.0 11.9 17.9 26.9 35.8 4501135130.0468 15.9 21.2 31.8 47.7 63.6 2126120.0218 14.8 19.8 29.7 44.5 59.4 4106130.0092 12.5 16.7 25.0 37.5 50.0 5001174140.0603 27.3 41.0 61.5 82.0 2164150.0284 25.8 38.6 58.0 77.3 4144150.0125 22.6 33.9 50.9 67.9
