Shell And Tube Heat Exchangers

Shell and Tube Heat Exchangers, Pressure Vessels, Columns, Filter Dryers, Reactors and Complete Pre-Assembled Units Features: 1. Intensified Heat Transfer The spiral copper coil pipe is fixed by the cantilever construction. As the hot mediators(saturation steam or high-temperature water)pass the pipe, The pipes high-speed round trip motion causes perturbation motion of the water around the heat exchanger tubes forcedly, and this increases the heat transfer coefficient K, reduces the fluids thermal resistance on the tubes outer wall l/a0, and enhances the total heat transfer coefficient.2. Less solid fouling Bcause of the coil pipes float with high speed, the fouling will be deposited and adheres to the pipes outer wall difficultly during the operation process. At the same time, Even though there is a little fouling on the pipes outer wall, the fouling will break off automatically because the coil pipe will flex along with temperature change,therefore the traditional fouling-release technique is needless and the heat exchanger can keep the best work condition for long term.
