Heat Exchanger

A Heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. We designs as per design Code IS-2825, AMSE SEC. VIII, TEMA, API-660 etc.
•    SHELL AND TUBE HEAT EXCHANGERS
 Shell and tube heat exchanger is the most common type of heat exchanger in all Industries. Mostly used in higher-pressure and Higher Temperature applications. These types of Heat exchangers are having two divisions one is shell and other is Tubes. Here One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. For this purpose seamless/ERW or Rolled pipes are used for shell. And Seamless tubes are used for Tubes. 
•    U TUBE BUNDLE HEAT EXCHANGERS
U tubes can duplicate any existing bundle to include dimensions, materials and performance. 
A heat-exchanger system consisting of a bundle of U tubes hairpin tubes surrounded by a shell outer vessel. one fluid flows through the tubes, and the other fluid flows through the shell, around the tubes. 
One of the most common applications is the cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs.
