Welded Plate Heat Exchangers

Overview

Welded plate heat exchangers combine the high heat transfer efficiency and compact size of PHEs with the high pressure and temperature capability of shell-and-tube types. The heat exchange core is formed by alternating peripheral welding of plates, with overall heat transfer coefficients of 3500-6000 W/m²·°C. Temperature range from -196°C to 900°C, pressure from vacuum to 6.0 MPa. The welded construction causes scale to self-detach during thermal cycling. Widely used in chemical process, refining, and power generation for high-temperature/high-pressure conditions.
