Semi-welded Plate Heat Exchanger for Condenser for Seawater

Semi-welding is a special welding method that achieves efficient heat transfer and sealing by partially welding the heat transfer plate and the cooling plate together at high temperatures. This welding method only welds part of the area to ensure heat transfer efficiency, while reducing the amount of welding material used.

Semi-welded plate heat exchangers offer many advantages, including high heat transfer efficiency, compact design, low pressure drop, reliable sealing and low risk of leakage. They are often used in industry for heat exchange processes such as heating, cooling and heat recovery.

Heat exchangers are assembled by a series of regular heat exchange plates, through which heat is exchanged. The structure of the Semi-Welded Plate Heat Exchanger is that every two corrugated plates are positioned back to back and welded together by laser along a sealing groove designed for the gasket of the semi-welded PHE as a "box".Brazed Heat Exchanger plate is only 304, 316L material.Gasket plate heat exchanger plates in addition to stainless steel, there are titanium plates, 254SMO, Hazelloy and so on, the thickness is generally 0.5-0.8mm.
