Mechanical Design of Heat Exchangers - And Pressure Vessel Components | Krishna P. Singh | SpringerWhenever a temperature gradient exists between two fluids, energy is transferred by heat transfer process. Classification: Based on the applications, heat exchangers are classified as boilers, condensers, heaters, coolers, recuperators etc. Depending on the configuration of fluid flow paths, heat exchangers are classified as parallel flow co-flow heat exchangers, counter current counter flow heat exchangers and single pass cross flow heat exchangers and multi pass cross flow heat exchangers. The most important difference between the four types lie on the relative amount of heat transfer surface area required to produce a given temperature rise for a given temperature difference between the two fluid streams where they benter the heat exchanger. Heat exchangers are employed in varied installations such as steam power plant, chemical processing plants, building heating, air-conditioning, refrigeration system etc to carry away the heat carried by the gases and it cools the gasses to a sufficiently low temperature, using a suitable fluid. Regenerative Heat Exchangers In Regenerative Heat exchangers the hot and cold fluid flow through the one and same passage and heated surface is alternately exposed to the hot and cold fluids.
Intergraph PV Elite Tutorial - Shell and Tube Heat Exchanger
Pressure Vessel Engineering Ltd. Expansion bellows. Three types of flanges are found in shell and tube exchangers, name. Joints for High Pressure Closures.
The software includes also an optional module allowing the calculation of workshop hours or costs by means of customizable tables providing times and prices for all the possible shop operations. The element from which a recuperative matrix is built up is mainly of two kinds, the fluid flows along the tubes on the inside and along across the tubes on the outside. For exchangers with multiple tube passes, the channels are fitted with flat metal plates which divide the head into separate compartments. Apart from other standard stainless steel materials we are experienced in a range of specialty materils:.
SHELL & TUBE HEAT EXCHANGERS
The Shell and Tube, other types of exchangers are increasingly used? The Shell and Tubethe Air Cooled and the Plate-type Exchanger are the three most commonly used types of exchangers in the chemical and process industries. Efforts to overcome this disadvantage resulted in the introduction of straight tube configuration. With increasing effort in recent years exchangerw reduce weight and size and increase efficiency, the Air Cooled and the Plate-type Exchanger are the three most commonly used types of exchangers in the chemical and process industries.
Any reduction in diameter leads to an increase in the number of tubes for given mass flow and requires new methods for fixing in tubes kechanical plates of the headers. Except for special high pressure heads, the partition plates are always welded to the channel barrel and also to the adjacent tubesheet or cover if either of these components is in turn welded to the channel.

Because the program is easy to learn and use, it is perfect for both regular and occasional users requiring fast start-up and confidence in their safety code calculations. Benefit from faster workflows thanks to tubesheet design and analysis, rectangular and non-circular vessel analysis and individual component analysis. PV Elite has been a trusted solution for owner operators, fabricators and engineering consultants for over 25 years. Graphical representation of analysis models helps ensure confidence in the input and results. Users can view and manipulate models with complete ease.
The most common tube length range is to mm for removable bundles and to mm for the fixed tube type. Tube Sheets: Tube sheets are used to keep the tubes in position. Its performance not only depends upon the temperature difference but also on relative humidity of air. Exchangrs tube joints can be produced at the "outer" face of the tubesheet or downhole at the "inner" face of the tubesheet. The mechanical design is analysed using B-JAC software and finds out that the design is safe.
The Classic software allows to meet many calculation and cost evaluation needs for pressure vessels and heat exchangers. The following packages are available:. Software for mechanical design of pressure vessels and heat exchangers in accordance with the harmonized standard EN part 3. See specifications and norm. Software for mechanical design and checking of testing requirements for pressure parts and pressure vessels made of spheroidal graphite cast iron SCGI according to EN Part 6. In general the rules in the relevant parts of EN Parts 3 are applicable for spheroidal graphite cast iron, taking into account additions and limitations provided in EN
