It is of wall type heat exchange with wall surface of the tube bundle enclosed in the shell as the heat transfer surface. The tubular heat exchanger is characterized by sturdy structure, strong adaptability and large flow area, and is easy in scale removing. There are six varieties of such tubular heat exchangers: fixed tube plate heat exchangers, floating head heat exchangers, U-tube heat exchangers, stuffing box heat exchangers and eddy current hot film heat exchangers, etc. It is suitable for the high temperature and high pressure environment or the conditions where large-sized heat exchangers are needed in the production of chemical industry and petroleum industry.
-- Heat exchange area: 0.5~500 m2
-- Nominal pressure: 0.25~2.5 MPa
-- Temperature: -40~400℃
-- Number of tube passes: 1~2 or more
-- Material: carbon steel, stainless steel, PTFE, etc.
