V-type Corrugated Plate to Plate Heat Exchanger Oil/Gas
Product Description
Product Introduce
Plate heat exchanger is a new efficient and compact heat exchanger that has developed and extensively used in the recent decades. It consists of multiple parallel corrugated-surface thin metal sheets that overlap and are then fixed by lamp plates and bolts. The cold working fluid and the hot working fluid flow through the narrow and winding passage made of two neighboring plates alternately and realize cold and heat exchange through the plates separating the two working fluids.
Thanks to its structure and heat exchange principle, it is characterized by compact structure, small floor area, high heat transfer coefficient and operation flexibility, wide application range, small heat loss, easy installation and cleaning, etc.
Plate and gasket
The plate materials and the gasket materials mainly depend on the corrosive properties and temperatures of the cold exchange medium and the heat exchange medium. The plate heat exchanger's plate materials and corresponding applicable places are given in Table 1 and its gasket materials and corresponding applicable places in Table 2 for your reference.
