Water - Cooled Shell and Tube Heat Exchanger
High Pressure Evaporator
First of all, according to the media selection materials, pipe flange all grade Ⅲ forging, equipment flange
full screw studs by magnetic detection, Ⅱ qualified.
If the low-temperature fasteners (equipment flange) need to do the impact test. The rest according to U-
type heat exchanger design. If the media is highly harmful, the material carbon steel will consider the heat
treatment, air tightness detection.
High-pressure U-type heat exchanger, tube tube plate and shell is the overall structure is not removable,
tube box flat cover with reverse flange connection, shell side of the tube plate connection structure.
1, multi-shell case shell flow
2, the pipe box separator temperature difference stress and heat transfer
3, the management of the flow
4, the management of high pressure, shell low pressure, pipe joints for leakage inspection
5, the pipeline should use the appropriate sealing structure
6, the assembly and control of the bundle should be convenient
