Mechanical design of heat exchangers and pressure vessel components pdf
PV Elite | Hexagon PPMOur main area of expertise is in the production of distillation and absorption columns, shell and tube heat exchangers and pressure vessels. We are used to working with many different process media: Air, sea water, fresh water, steam, oils and the whole spectrum of process solutions. Each and every one of them demands levels of knowledge that our design engineers and production staff master through both theoretical and practical experience. To support our clients with optimisation of capacity and production economy the choice of material in the equipment is vital. The most common materials we work in are the stainless standard steels 1. Apart from other standard stainless steel materials we are experienced in a range of specialty materils:. We specialise in tailor-made units that are optimised according to application and the customer's requirements.
Mechanical design of heat exchangers and pressure vessel components
The shell and tube heat exchanger is shown in figure 1. Partition plates are made use for multipass flow. Figure 3. Class C for "generally moderate requirements of commercial and general process applications,".Jose Luis Rattia. Sourendra Dey. Shell: The shell consists of a cylinder made vrssel seamless pipe rolled and welded with a bolting flange at each end. The E-mail Address es you entered is are not in a valid format!
Successive baffles are arranged in such a way as to create continuous helical and near plug-flow conditions on the shell side. Learn more about Scribd Membership Bestsellers. It is more expensive than roller expansion but can produce sesign joints.

Whenever 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.
Tubes may be purchased to minimum or average wall thickness. Castings can accommodate greater complexity of shapes and may unify different functions in the same part. Figure RCB Designing to avoid such operational perils requires a thorough grounding in several disciplines of mechanics, and a broad understanding of the inter relationship between the thermal and mechanical performance of heat exchangers.

NozzlePRO is a standalone solution that enables users to quickly and easily perform finite element aalysis FEA of individual pressure pressurd and piping components. This configuration consists of a shell assembly with a flange on each end and the tube is fixed at the both ends.
