Don’t carbon steel flanges have any steel stamp markings? Is there no specification, model, or standard number marked on the outer circle of the flange?
Generally, carbon steel flanges are marked with a steel stamp. Stamp markings usually include information such as the flange’s specifications, model number, and standard code. These markings can help users correctly identify and select the appropriate flange. However, in some cases, certain carbon steel flanges may lack steel stamp markings, especially those that are non-standard or of low quality. Therefore, when purchasing carbon steel flanges, it is best to choose products with steel stamp markings to ensure quality and authenticity. .
It is necessary to mark the steel stamps; in particular, information such as the material type, pressure rating, and forging grade are not visible and can easily lead to confusion. This may result in using materials of higher specifications than required, causing waste, or using materials of lower specifications than appropriate, creating safety hazards.
They all have them, unless it’s a product with no brand, no quality control, and no production information{:9001:}
