What is the purpose of floating head in heat exchanger?
A floating head exchanger is used to make removal of the tube bundles possible and to allow for significant expansion of the tubes. At the end of the floating and stationary tubes sheet, exchanger tubes are fixed.
What is a floating head?
: a flesh hoop of a drum entirely free from the shell.
What is pull through floating head?
Floating head designs of head exchangers The simplest is a “pull-through” design which allows the tube bundle to be pulled entirely through the shell for service or replacement. In order to accomodate the rear head bolt circle, tubes must be removed resulting in a less efficient use of shell size.
What is fixed head heat exchanger?
Fixed head shell and tube heat exchanger. This is the simplest and most popular type of exchanger. These types of exchangers are constructed with the tubesheet integral to the shell. It uses straight tubes secured at both ends into tube sheets, which are firmly welded to the shell.
What is the advantage of the floating head heat exchanger over the conventional fixed head heat exchanger?
Floating head heat exchangers are suitable for heavy duties associated with high temperature and pressure and large temperature differences. Fouling fluids can be handled because cleaning of tubes from inside and outside is possible.
What is floating tube sheet?
A floating tubesheet style heat exchanger consists of a removable tube bundle made up of straight tubes, tubesheets, tie rods and baffles. The name floating tubesheet comes from the fact that the tubesheet on the tail end of the exchanger is not fixed in place, like the one on the front end of the bundle.
What is a floating tube sheet in a heat exchanger?
What is a heat exchanger used for?
Heat exchangers are used to transfer heat from one medium to another. These media may be a gas, liquid, or a combination of both. The media may be separated by a solid wall to prevent mixing or may be in direct contact.
What is a shell and tube heat exchanger used for?
Shell and tube heat exchangers are widely used in applications, which require cooling, or heating large volume of process fluids or gases. There are a number of different types of shell and tube heat exchanger designs to meet several process needs in virtually every industry.
Why is shell and tube heat exchanger widely used in industry?
Why are Shell and Tube Heat Exchangers Used? Shell and tube heat exchanger is used in various industrial process applications because they can perform tasks such as: Removal of process heat and feed water preheating. Cooling of hydraulic and lube oil.
How are heat exchanger tubes made?
Tube sheets usually constructed from a round, flattened sheet of metal. Holes for the tube ends are teen drilled for the tube ends in a pattern relative to each other. Tube sheets are typically manufactured from the same material as tubes, and attached with a pneumatic or hydraulic pressure roller to the tube sheet.
How are heat exchangers used in industry?
About industrial heat exchanger Industrial heat exchangers are applied in various industrial applications such as power plant generation, petroleum oil and gas industry, chemical processing plant, transportation, alternate fuels, cryogenic, air conditioning and refrigeration, heat recovery and other industries.
