The Yili series of shell-and-tube heat exchangers are corrosion-resistant heat exchange units, featuring an integral all-plastic structure. They are made by secondary processing of integral reinforced polypropylene pipes, pure polypropylene plates, modified polypropylene plates, and graphite-modified polypropylene heat exchange tubes.
This product features a fixed tube plate shell and tube structure. The heat exchange tubes in the Yili brand SPGH series heat exchangers are specially designed thin-walled tubes made of graphitized polypropylene, with a graphite content of 50% (by weight).
This product maintains the advantages of polypropylene equipment, such as corrosion resistance, lightweight strength, and non-adhesive properties, while also significantly enhancing the equipment's heat transfer performance. The overall heat transfer coefficient of the equipment reaches 250~400 KCal/m h°C.
