Industrial Gasket and Plate Heat Exchanger

Industrial Gasket and Plate Heat Exchanger   Product DescriptionThe plate heat exchanger is a new efficient and compact heat exchanger that has developed and extensively used in 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.  StructureThe plate heat exchanger consists essentially of heat transfer plates, gaskets and a clamping device. 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. The two mediums have a mean temperature difference as small as 1ºC and heat recovery efficiency higher than 99 percent. Based on the same pressure loss, the plate heat exchanger has, compared with a tubular heat exchanger, a heat transfer coefficient two to four times higher, a one-third floor area and two-thirds metal consumption. It is therefore an efficient and energy, material and investment saving advanced heat exchanger. It is now widely used in industrial fields such as chemical industry, petrochemical, food, machinery, central heating, metallurgy, power, ships, paper-making, textile, pharmaceutical industry, nuclear industry, seawater desalination and combined heat and power generation to meet the requirements of processes such as cooling, heating, condensation, concentration, sterilization and residual heat recovery. It has become a highly competitive product in the heat exchanger field or evenly has replaced conventional tubular heat exchangers. With its development, it will be used in more and more fields.   Product ParametersPlate and gasketThe 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.Table 1 Plate Materials  Material nameThickness (mm)Material gradeApplicable placeStainless steel0.5-0.8304,321,316,316LPlaces with serious corrosion caused by acid or base mediums and places not suitable for chloride ionsCommercial pure titanium0.5-0.8TiAlkali or salt making places, sea water desalination places, low-temperature places, freezing places or places with chloride-ion corrosionNickel0.5-0.8NiPlaces resistant to corrosion, hot alkali liquor corrosion, neutral solutions or subacid solutionsAcid-resistant steel0.5-0.8RS-2, SM0254, HC-276Sulfuric acid field and the fields with acid corrosionTable 2 Gasket Materials  Material nameCodeApplicable temperatureApplicable placeNBRN-20~110ºCWater, non-polar oil, mineral oil, lubricating oil, silicon oil, etc.EPDME-20~150ºCSteam, water, ozone, polar chemical mediums, alcohol, weak acids, weak bases, salt solutions, etc.Chloroprene rubberC-40~100ºCAmmonia, mineral roil, lubricant, freon, etc.FluororubberF0~180ºCInorganic acids, bases, mineral oil, halohydrocarbon and oxidantSilicon rubberQ-40~200ºCFood field, etc.Our factory:Company Profile     /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
