PRODUCT DESCRIPTION
Stainless steel heat exchanger is the most widely used type heat exchanger made by stainless steel. It has very good anti-oxidation properties, safe and hygienic, can be used at high temperature and high pressure, so it can be widely use in food, medicine, heating, domestic water and other fields. Stainless steel has better heat transfer effect than the carbon steel, and the service life is longer.
STRUCTURE
The structure of stainless steel shell and tube type heat exchanger is composed of shell, heat transfer tube bundle, tube plate, baffle and lid/head. The shell is mostly cylindrical type, with tube bundles installed inside, and both ends of the tube bundles are fixed/welded on the tube plate. Two fluids, hot and cold, for heat exchange, one flows inside of the tubes, called the tube-side fluid; other flows outside the tube, called the shell-side fluid. In order to improve the heat transfer coefficient of the fluid outside the tube, several baffles are usually installed in the shell. The baffle can increase the velocity of the fluid on the shell side, forcing the fluid to pass through the tube bundle several times laterally according to the prescribed path, and enhance the degree of fluid turbulence. The heat exchange tubes can be arranged in equilateral triangles or squares on the tube sheet. The equilateral triangle arrangement is relatively compact, the fluid outside the tube has a high degree of turbulence, and the heat transfer coefficient is large; the square arrangement is convenient for cleaning outside the tube, and it is suitable for fluids that are prone to scaling.
stainless steel shell and tube type heat exchanger also can be designed vertical or horizon according to process requirement.
ADVATAGE OF PRODUCTS

Low maintenance cost, easy to operate, long scale cycle and easy cleaning;
Compact structure, small footprint, light weight and easy installation.
CAUTION:
Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary mild steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry.
MATERIAL
Model/Code/Type 304, 316L are chromium-nickel alloys that common use stainless steel material for shell and tube type heat exchanger. Generally, applicating as a liquid-liquid heat exchanger, SS304 use on shell-side for cooling or heating by working medium pass through (such as water, refrigerating brine, thermal oil), and SS304 or SS316L use on tube-side according to the corrosion property of media. Applicating as a condenser, the vapors will pass through shell-side and condensate to liquid, SS304 or SS316L should use depend on the corrosion property of vapor.
