A Heat exchanger is a gadget to exchange warm shape one liquid/Gas to another. There are different sorts of warmth exchangers utilized in process funneling. Shell and tube warm exchanger is the most broadly utilized warmth exchanger
Fundamental Components of Shell and Tube Heat Exchanger:
Regularly a Shell and Tube Heat Exchanger comprise of two compartment/area one is shell side and other is channel/tube side
Shell side area comprises of the accompanying segments: Shell, Cover, Body Flange, Nozzles, Saddle bolster .
Channel/Tube side segment comprises of the accompanying segments: Channel, Cover , Body Flange, Nozzles, Tube Sheet and Tubes (Tube Bundle)
Tie poles and Spacers
Tube will be put with a min. c/c separation of 1.25 times the tube outside distance across of the tube. At the point when mechanical cleaning of tube is indicated then min. cleaning path of 6.4 mm will be given.
Sort of Shell and Tube Heat Exchanger:
TEMA Exchanger Type
R – Refinery and Petrochemical Application
C – General Process Application
B – Chemical Process Application
TEMA Heat Exchanger appropriate Criteria
Inside distance across 2500 mm Result of ostensible distance across (mm) and configuration weight (kPa) of 5 x 106
Configuration codes utilized for Heat exchangers:
Programming interface 660/ISO 16812 ( Shell and Tube warm exchangers for general refinery benefit )
ASME SECT.VIII Div.1 (UHX) or Div.2, PD 5500, EN 13445, AD 2000 Merkblatt.
TEMA – Tubular Exchanger Manufacturers AssociationShell DEP 188.8.131.52 and DEP 31.21.01.30
Programming for utilized Thermal Design:
HTRI – Heat Transfer Research Institute
HTFS – Heat Transfer Research and liquid stream benefit
Outline of Shell and Tube Heat exchangers:
Astound leeway, Baffle separating and thickness according to TEMA table RCB – 4.3
Tie bar size and nos. according to TEMA table R-4.71 for class – R
Fringe GASKET: The min. width of fringe ring gasket for outside joints will be 10 mm for shell sizes up to 584 mm and 12 mm for all bigger shell estimate.
PASS PARTITION GASKET: The min. width of gasket web for pass parcel of channel will not be under 6.4 mm for shell sizes up to 584 mm and 9.5 mm for all bigger shell estimate. Gasket joint will be limited compose
Shell and Head configuration is done according to chosen Pressure vessel Design Code, for example, ASME , EN or AD
The Most generally utilized outline code over the world is ASME Sect. VIII Div.1 and 2 Body/Girth Flange Design according to Appendix – 2 of ASME Sect. VIII Div.1 Tube sheet configuration is Mandatory according to UHX of ASME Sect. VIII Div.1 Tube sheet is plan for following three cases. Tube side weight (Pt) acting and Shell side weight (Ps) is Zero Shell side weight (Ps) acting and Tube side weight (Pt) is Zero Shell side weight (Ps) acting and Tube side weight (Pt) acting It would be ideal if you consider the impact of Vacuum in above load cases Tube sheet Design recipe dependent on hypothesis of Flat Plates
