A wide range of industries – oil and gas, food, chemical, refrigeration etc. – utilize shell and tube heat exchangers. Exchangers have been given a variety of names, depending on their heat transfer functions. Heat exchanger construction styles may be broadly divided into three categories: fixed tubesheet, u-tube and floating tubesheet, each with its own purpose. They are designed to transfer heat between fluids or gases of different temperatures in order to perform cooling or heating processes on a medium passing it through. A heat exchanger consist of heat-exchanging elements such as a core or matrix containing the heat-transfer surrface, and fluid distribution elements such as headers or tanks, inlet and outlet nozzles or pipes, etc. Usually, there are no moving parts in the heat exchanger. However, there are exceptions. To increase heat transfer area, secondary surfaces known as fins, may be attached to the primary surface. Creo 3D Design Ltd can undertake the mechanical design of all types of shell & tube heat exchangers to most configurations listed in the following codes: TEMA, ASME VIII DIV 1 and EN 13445. We offer complete set of calculations evaluating the compliance with a relevant code, 2D fabrication drawings based on 3D geometry and FEA analysis report if required.
