U tube heat exchangers, each tube is bent into a U-shaped, both ends are fixed on the same tube sheet, each tube can be freely retractable, thus solving the problem of thermal compensation. The tube length is at least two passes. The tube bundle can be pulled out for cleaning and the tube can expand freely. The disadvantages are that the inner wall of the pipe is difficult to clean, the pipe replacement is difficult, and the number of pipes arranged on the pipe plate is small. The advantages are simple structure, light weight, suitable for high temperature and high pressure conditions.
Tube-sheet heat exchanger is a kind of high efficient heat exchanger equipment, suitable for steam-gas, vapor-liquid, liquid-liquid, heat transfer to liquid.
The tube condenser is divided into three types according to the material: carbon steel tube condenser, stainless steel tube condenser, and carbon steel and stainless steel mixed tube condensation.
