Following table from the TEMA criteria describes the various possible options for each of the 3 broad parts.Moreover depending on how tube bundle can be fixed to the top finish or rear end cover up, we have got 3 broad varieties of cover tube heat exchanger design.Set tubesheet getting the least expensive cover pipe exchanger kind, as very long as we dont use any extension joint.Moreover, absence of flanged joint parts helps to minimize the leakage of the shellside liquid.
Fixed tubesheet exchangers require that a clear fluid must become used on the covering side. All the tubes begin from upper half of this tubesheet, create a U turn in the covering and arrive back to the lower half of the same tube sheet. Therefore a U pipe exchanger is usually the favored option where there is certainly high temp distinction between cover tube aspect fluids and tube expansion will be expected. Hence U tube exchangers are normally not really desired where we require to make use of a unclean or fouling program on the tube side. Tema Standards Free Of ChargeWhile the other end is free of charge to increase or suspended in the shell side. Furthermore, the floating head cover up can become easily eliminated to mechanically clear insides of the tubes. Therefore also unclean and fouling providers can also be utilized on the pipe side. ![]() ![]()
