Plate heat exchanger is one of the most popular heat transfer equipment widely used in heating, cooling, condensation and evaporation process in industries of chemical engineering, chlor-alkali, oil and gas, food, metallurgy, papermaking, medical and central heating as it has advantages of higher transfer coefficient, smaller size, less thermal losses and easier assembly. NB/T47004-2009 is the standard the company follow in manufacturing.

Heat exchange plate is the key component in plate heat exchanger, usually made by materials including titanium and titanium alloy, nickel and nickel alloy, stainless steel. By computer calculation, the length-width ratio, ripple depth, ripple pitch and ripple angle are optimized so that the transfer coefficient is fit for the pressur.
