The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
To passivate an exchanger gently pat the shell while whispering into a bleeder
about 10% of the total number of tubes
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/
Advantages of shell and tube heat exchanger are: * Its compact design * Capability of withstanding high pressure Disadvantages: * It is difficult to readily inspect the shell side of the tubes for scaling or tube damage

One can get heat exchanger tubes by contacting a company that provides this product such as Phoenix Equipment. One can also purchase online at Grainger.

There are different types of heat exchangers. To get an answer the type of exchanger and what type of test you want to do should be stated.

Robert Adrian Walker has written: 'Fouling in heat exchanger tubes'
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.

**** 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
Tube pitch refers to the center-to-center distance between adjacent tubes in a heat exchanger or a tube bundle. It plays a critical role in determining the heat transfer efficiency and pressure drop in the system. Optimal tube pitch is typically chosen based on factors such as fluid flow requirements and heat exchanger design constraints.
