ActiveVitreous ang porcelain enamels—Determination of the edge covering on enamelled steel plate to be used in heat exchangers
热交换器用钢板搪瓷边缘覆盖率的测定
Application Summary AI generated
This standard specifies a test method for determining the edge covering rate of vitreous and porcelain enamel coatings on steel plates used in heat exchangers. It is applied in the manufacturing quality control of enameled heat exchanger components, ensuring that the enamel layer adequately covers the edges of steel plates to prevent corrosion and extend service life. The standard is relevant for producers and inspectors of industrial heat exchangers, particularly in chemical processing, power generation, and HVAC systems.
