ISO 28763 is an International Standard that discusses vitreous and porcelain enamels, for optimal durability and performance of heat exchangers.
ISO 28763 specifies the minimum requirements and the functional characteristics of enamel coatings applied by any process, such as wet dipping, wet flow-coating, wet spraying, wet electrostatic spraying, wet electrodeposition, or dry-powder electrostatic spraying, to profiled steel heat exchanger panels in regenerative heat exchangers, before and after packing in baskets.
For very severe service conditions, or to obtain extended operational life, more stringent limits can be agreed upon between customer and supplier.
ISO 28763 on vitreous and porcelain enamels is relevant to:
A heat exchanger is a device that transfers heat from one fluid (liquid or gas) to another, and is widely used across engineering applications, in both heating and cooling processes. However, for their durability and performance, best industry enamelling practices are critical.
ISO 28763 provides you with the guidelines for enamel coatings applied on profiled steel heat exchanger panels in air-gas and gas-gas heat exchangers, that improve corrosion, temperature and chemical resistance qualities.
With ISO 28763-compliant vitreous and porcelain enamelling, you can ensure that the heat exchangers do not deteriorate from permeability of liquids and vapours, thus allowing you to control undercutting caused by rust and corrosion. Overall, these best industry requirements of characteristics and technical properties can impart a high level of strength to the enamelled steel.
