Shell and tube heat exchangers are used for oil/gas/chemical/food and beverage/pharmaceuticals 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 [...]
The concept and operation of a shell and tube heat exchanger are rather simple and are based on the flow and thermal contact of two liquids. The name of a shell and tube heat exchanger serves as an explanation of the process, which is the exchanging of temperature between two fluids. In a heat exchanger, [...]
1) The heat exchanger should be tested for water pressure at 1.5 times the maximum working pressure. The steam part should not be lower than the steam supply pressure plus 0.3MPa; the hot water part should not be lower than 0.4MPa. Under the test pressure, keep the pressure without drop for 10min. shell tube heat [...]
