Double-wall safe plate heat exchanger with two plates welded together instead of a single plate and tube heat exchangers, plate once cracks or perforation pattern tube heat exchangers, fluid by two plates of flows between the outside, it is easy to be found and to take measures in order to avoid mixing with each other in two heat transfer medium, which led to pollution or harmful reactions. Double-wall safe plate heat exchangers are widely used in the metallurgical industry, power industry, pharmaceutical industry, chemical industry and so on. Wide-gap plate heat exchanger plates with a large depth corrugated tube heat exchangers, flow channel diameter up to 3 times that of traditional plates and fewer points of contact between the plates, so the flow smooth, fluid can flow channel "free" flow. With respect to the tubular heat exchanger U-tube heat exchanger, due to the ripple can lead to a high degree of turbulence, so the heat transfer efficiency, and compact and space-saving. Wide-gap plate heat exchangers are available in liquid or high-viscosity liquid in the paper, textile, sugar, food processing and other industries containing fibers or coarse particles. Tube heat exchanger tube heat exchanger _ _ machinery provided by Jinan Sheng Mai Mai Sheng Machinery Co., Ltd. Jinan Mai Sheng Machinery Co., Ltd.
