Shell & Tube Heat Exchangers are used in place of conventional coil type glass condensers where large heat transfer areas are required in confined spaces. Shell & Tube Heat Exchangers can be used as : Main Condensers Tail Gas (Guard) Condensers Thermo siphon Reboilers Product Coolers Waste Heat Economizer Shell & Tube Heat Exchangers are available in single pass or multipass on tube side Only. Material of Construction of tubes 3.3 Expansion Borosilicate Glass Graphite Titanium Stainless Steel (SS 304/316) Material of Construction of Shell 3.3 Expansion Borosilicate Glass Carbon Steel Stainless Steel (SS 304 / 316) PP / FRD MS - PTFE Lined Tube sheets are invariably 100% PTFE or Reinforced PTFE Shell & Tube Heat Exchangers Supplied by Sigma Glass are uniquely designed where the sealing is done with PTFE Ferrule only in some cases and in some cases with PTFE gland Packing and O rings.Also the tie rods are invariably PTFE with Glass spacer tubes. Typical Heat Transfer Co-efficients in kcal/mA².A°c.hr Liquid Liquid Cooling water - water 500 - 600 water - organic solvent 250 - 600 water - oil 75 - 350 water - air 25 - 250 Liquid Gas Condensation water - water 600 - 900 water organic solvents 400 - 600 Evaporation steam organic solvents 400 - 600 steam water 500 - 900 Our heat exchangers are well standardized for ease of procurement of spares. Salient Features Universal corrosion resistance Can be installed both in vertical or Horizontal positions Easy replacement of tubes and repair and cleaning Low maintenance cast High heat transfer efficiency Standard shell & tube Heat Exchangers are available from 2.5m2 to 25.0m2 HTA |
