Characteristics and Application of All Welded Heat Exchanger

29 Dec 2018

All welded heat exchanger is a general heat exchanger with corrugated metal sheets as heat transfer surface. The metal sheets are sealed by welding. This type of heat exchanger is efficient and compact. It is widely used in liquid-liquid heat exchange, liquid-steam heat exchange, gas-gas heat exchange and other occasions. It is an ideal equipment for water-water, water-steam, water-oil, gas-gas heat transfer.
All welded heat exchanger uses corrugated metal plates as heat transfer elements and is sealed by welding process. This greatly improves the safety and reliability of heat exchangers, has the characteristics of high heat transfer coefficient, low pressure, small occupied, areacorrosion resistance, long service life, not easy to accumulate ash, easy to clean and so on etc. At present, gas-gas fully All welded heat exchangers are more and more used for preheating in various industrial furnaces.

Application field of All welded plate heat exchanger
All welded heat exchanger is a kind of general heat exchange equipment. It is an ideal equipment for water-water, water-steam, water-oil, gas-gas heat exchanges. It is widely used in petroleum, chemical industry, electric power, metallurgy, food and other fields.
(1) Water-water heat exchanger: used for heating or cooling industrial or domestic water, such as central heating, domestic hot water, circulating water cooling, etc.
(2) Water-oil heat exchanger: used for heating or cooling industrial oil, such as hydraulic oil cooling, quenching oil cooling, oil cooling, etc.
(3) Water-steam heat exchanger: used for heating industrial or domestic water or condensation of steam, such as process water heating, circulating water heating, etc.
