TEK-FIN Titanium & Stainless Steel Low Fin Tube:
Product Detail
Abstract:
Fin tube provides 3 times the external surface area of bare tube.
Integral low fin tubing yields numerous benefits for shell and tube heat exchangers including reduced size and cost for new equipment, increased performance of existing equipment. The cost of shell and tube heat exchangers can be reduced up to 50% through the proper application of low fin tubing.
Application:
The Integral low fin tubes are widely used in chemicalprocess. Especially applicable between air or other gases on the fin-side and a fluid on the tube-side.
When to Consider Integral low fin tube.
Shell side heat transfer is controlling.
Expensive materials of construction are required.
Debottlenecking an existing exchanger.
Retrofitting or upgrading with new tube material.
Meeting a stringent space or weight requirement.
FIN TUBE MEETS THE FOLLOWING QUALITY STANDARDS
ASTM B891 Seamless and Welded Titanium and Titanium Alloy Condenser and Heat Exchanger Tubes With Integral Fins
ASTM A1012 Seamless and Welded Ferritic, Austenitic and Duplex Alloy Steel Condenser and Heat Exchanger Tubes with Integral Fins
ASTM B924 Seamless and Welded Nickel Alloy Condenser and Heat Exchanger Tubes with Integral Fins
ASTM B359 Copper and Copper Alloy Seamless Condenser and Heat Exchanger Tubes with Integral Fins.
