What are the standards for plate heat exchangers?

Thread Content

Standards are an important basis for organizing production and quality control, as well as the most fundamental technical requirements. Below, Puripler provides a detailed introduction to the standards for plate heat exchangers: \"Plate Heat Exchangers GB16409-1996\". This is the first standard for plate heat exchangers issued in China; it applies to detachable plate heat exchangers with a design pressure of no more than 2.5 Mpa and a design temperature of no more than 260°C, and it specifies the requirements regarding design, manufacturing, inspection, and acceptance. \"Plate Heat Exchangers for Refrigeration JB8701-1998\" is the first industry standard for plate heat exchangers issued in China. It applies to plate heat exchangers used in refrigeration systems that employ liquefied gases as refrigerants, with a design pressure of not more than 4.0 MPa and a design temperature ranging from 0 to 200°C ； It is also applicable to other applications involving non-detachable plate heat exchangers under similar conditions of pressure, temperature, medium, etc ； It specifies the requirements regarding design, manufacturing, inspection, and acceptance. Although this standard is not applicable to detachable plate heat exchangers, it includes most of the contents of CB16409-1996, with some provisions being more comprehensive and reasonable. \"Plate heat exchangers for the oil and gas industry ISO15547:2000(E)\” is the first international standard for plate heat exchangers to be issued. It is primarily applicable to the oil and gas industry, and is based on requirements or recommendations regarding orders. It covers topics such as the definition of relevant terms, mechanical design, material selection, manufacturing, inspection, testing, and preparation for shipment. \"Plate Heat Exchangers NBT47004\": This standard for plate heat exchangers is based on \"Plate Heat Exchangers GB16409-1996\" and \"Plate Heat Exchangers for the Oil and Gas Industry ISO15547:2000(E)\\", with certain modifications made; it does not cover welded plate heat exchangers. It specifies the requirements for the design, manufacturing, inspection, and acceptance of plate heat exchangers, and is applicable to detachable and semi-welded plate heat exchangers. \"Plate Heat Exchangers for the Food Industry QB1009-90\" is applicable to the food industry, such as in milk and beverages, but its scope of application is relatively narrow.
