ASTM stainless steel fin tube ,finned tube heat exchanger
HAOHUA INDUSTRY offers the widest variety of sizes available in the industry. All of our products are domestically sourced, developed, and produced, which means our customers have immediate access to exactly the products they need for their particular application. And you are assured of the highest quality and manufacturing standards and a local, concerned, customer service presence.
The strong connection between fin and base tube prevents loosening of fin because of heat stress, oxidization, corrosion etc., use at very high temperatures possible. This welded steel finned tubes configuration can be used in practically any heat transfer applications, and particularly suited for high temperature, high pressure applications. The important features of this configuration are efficient, effective bond of fin to tube under any conditions of temperature and pressure, and ability to withstand high fin-side temperatures.
These tubes are used with a wide range of material such as carbon steel, low alloys steel and stainless steel for corrosive flue gas or high temperatures. The finned tube can supply these tubes shaped in hairpin, with extremities bevelled.
As the fin strip is formed around the tube its outer (serrated) edge spreads, opening the segments like petals of a daisy. A continuous weld is applied at the point where the fin strip first begins to bend around the tube diameter using Vulcan's unique gas metal arc welding process. This welding process creates the strongest fin to tube attachment in the industry, excellent heat transfer characteristics, low fin-side pressure drop and little to no change in grain micro structure and physical characteristics even when 3%-9% chromium tubes are used. For a given pipe or tube size, the desired heat transfer surface area per unit length of tube can be obtained by specifying the appropriate fin height and/or number of fins per inch of length.
