Heat Exchanger Steel Tube

Heat Exchanger Tubes are used in Shell and Tube Heat Exchanger with all types of process industries.such as chemical processing, hydro carbon processing and oil refining, nuclear power generation and aerospace. stainless steel tubes offers superior corrosion resistance, which is ideal for many lightly caustic applications like cooling plant nutrient solutions or chlorinated water.Helically wound tubes generate a rifling effect internally which adds to flow turbulence and greatly improves heat transfer, Ample port sizes for both tube ports and shell ports to maximize flow rates.Tube and shell are both fully welded which helps ensure durability and unit longevity.
Heat exchanger tube in an extensive range of austenitic stainless steels, duplex stainless steels, nickel alloys, titanium and zirconium, suitable for all types of heat exchangers, such as seawater coolers, condensers, evaporators, heaters and reheaters.

We offer the market's widest selection of stainless steel grades and has extensive experience of manufacturing heat exchanger tubes.
Surface protection: Unless otherwise stated in order tubes are delivered with inner and outer surfaces temporarily protected with a film of light mineral oil.
Tubes ends: The tubes are supplied plain, square cut and on request the tubes can be deburred.
