Application Use of advanced manufacturing equipment and process control tools, tubes and flanges of hot-melt welding, assembly into the heat exchanger; Fluorine plastic (YQ TEFLON) heat exchangers suitable for surface treatment of chrome plating, acid copper, acid tin, zinc, electrolytic, acid plating, anodizing and chemical industry, hospitals, food and other corrosive solution heating, cooling, evaporation, concentration. Advantage According to customer requirements, design products strictly material, to meet the technical requirements process; Products using tubes ( 3mm, 5mm, 6mm, 12mm) penetration of both ends of the flanges are assembled to form a heat exchanger, import and export, and with (PP, PVC, PTFE, PVDF frame) assembly is fixed, the heat exchanger to prevent collision damage to the workpiece.
