The hydro-testing procedure of a shell and tube heat exchanger requires you to fill the shell and tubing with water that had a color dye added to it. Then, raise the internal pressure by 1.5 times the operating pressure suggested by the manufacturer. If there are any cracks in the vessel, the water will be forced out through the cracks.

What is a shell and tube condenser?
A heat exchanger with straight tubes in a shell that can normally be mechanically cleaned
Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
What is the assumption to design heat exchanger?
The assumption to design heat exchanger is that it must be a shell and tube device. This device must allow the transfer of heat from one fluid to another without mixing the two fluids.
What is an Impingement plate in an Heat Exchanger?
Impingement plates are installed on the tube side of a bundle. It is between the tubes and the inlet nozzle and serves to slow down and/or disperse the liquid as it enters the exchanger. This prolongs the life of the tubes in this area which, in turn, extends the life of the bundle.
What is the Water tube boiler design procedure?
You will find it in any mechanical engineering heat transfer book
What is the factors that effect on number of tubes in shell and tube heat exchanger?
The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
What is a shell and tube condenser?

Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
How you can increase the retention time in shell and tube heat exchanger?
the most effective way to do so is to reduce the flow of the heat exchanger

Why impingement baffle is introduced at the shell side inlet of a shell and tube heat exchanger?
increase to heat transfer coefficent
Advantage of shell and tube heat exchanger over double pipe heat exchanger?
**** you.......... pls somebody answer Double pipe heat exchanger consists of two concentric pipes of different diameters.One pipe is for hot fluid and another is for cold fluid.Both may have same flow direction(COCURRENT) and opposite direction(COUNTERCURRENT). Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present.One fluid hot or cold flow in shell and other hot or cold flow in the tubes. Also in case of shell & tube(S&T) the hot fluid will have more turbulence than in double pipe heat exchanger (HE) since there are no of tubes within a shell the area for convective heat transfer is considerably increased. so these are much more preferredTherefore the rate of heat transfer is greater in shell and tube because large surface area and enough contacting time
What is the difference between double pipe heat exchanger and shell and tube heat exchanger?
double pipe heat exchanger is made if two concentric tubes one carrying cold flow and the other one carrying hot flow. but shell and tube hear exchangers are made of a shell like a vessel filled with many thin tubes to transfer heat between fluids. there are more data available at : http://scopewe.com/double-pipe-heat-exchanger-design-part-1/
What has the author Antony Johnson written?
Antony Johnson has written: 'Flow, heat transfer and pressure drop on the shell side of a shell and tube heat exchanger'
Disadvantages of shell and tube heat exchanger?
it is difficult to remove the scales. we cannot use scale forming fluid through the shell because if we pass, the scales are formed and it corrodes the shell.
Why Don't we use odd number of tube passes in Shell and Tube Heat Exchanger?
It is difficult from cleaning point of view. Both end chambers have to be removed so as to clean the heat exchanger with odd nos of passes. Thanks & Regards Priyanka Karkera
What could make a crack in the tube side of shell and tubE heat exchanger?
Perhaps the crack in the tube side of the shell became too hot since it was next to the tube heat exhanger. Additional information about the machine or product you are using would greatly help in determining what the problem is.
