Condenser is a type of heat exchanger, condensing vapor into liquid, condenser unit consist of other parts including tube, condenser tube is a major component to delivery steam in refrigeration system, stainless steel tube have good properties to transfer heat to outside of tube, tube can be coil shape, to enhance efficiency, cooling fin tube is usually used.
Condenser is common device used in power station, to condense turbine exhaust steam into water, condensers can be designed and manufactured in small or large size according to application, In many cases, large condensers for industrial applications use water or some other liquid instead of air to remove heat.
Stainless Steel Condenser Tube
Stainless steel material is usually used in condenser system, not only for tubes, also other parts, like shell, certainly, stainless steel tube have good corrosion resistance, conductivity for heat as well as mechanical and physical properties.
Stainless steel grades often include TP304 | TP304L | TP316L | TP321 | 2205 | TP446 and others, selecting proper grade base on specific application, duplex steels have better properties to suitable for high temperature and corrosion environment.
Seamless, Welded Tubes
Both seamless and welded stainless steel tubes are available for condenser, tubes must withstand high temperature, low temperature or corrosion attack, so tubes are supplied under superior quality, avoid unnecessary repairing and maintenance.
Common standards for stainless steel condenser tube are ASTM A213 and ASTM A249, ASTM A268, A269, A688, A803, A789 AND A790 specifications can be chosen according to user requirement, heat treatment and bright annealing finishes can be offered to improve tube performance.
Condenser tube sizes are depending on size of designed condenser, generally in small sizes, outside diameter of condenser tubes typically ranges from 1/2 inch to 1-1/2 inch, wall thickness ranges from 0.035 inch to 0.065 inch, outside diameter tolerance can be over and below 0.1 mm, and wall tolerance can be over and below 10% of normal thickness, tight tolerances benefit condenser design.
