Shell and tube (tube shell) heat exchanger product classification:
Fixed tube plate heat exchanger
Floating head heat exchanger
U-tube heat exchanger
Double tube plate heat exchanger
Product structure:
Divided into single tube pass/double tube pass/multi-tube pass
Can also be customized according to customer needs

The shell and tube heat exchanger is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This heat exchanger has a simple structure, low cost, wide flow cross-section, and is easy to clean scale; but the heat transfer coefficient is low and the floor space is large. It can be made of various structural materials (mainly metal materials), can be used under high temperature and high pressure, and is the most widely used type.

Shell and tube heat exchangers are used for food and beverage

Shell and tube heat exchangers are used for chemical

Shell and tube heat exchangers include fixed tube plate steam-water heat exchangers, shell and tube steam-water heat exchangers with expansion joints, floating head steam-water heat exchangers, U-shaped shell and tube steam-water heat exchangers, corrugated shell and tube steam-water heat exchangers, and segmented water-water heat exchangers. The main control parameters of shell and tube heat exchangers are heating area, hot water flow, heat exchange capacity, heat medium parameters, etc.
