Notes: 1. This series of products meets the requirements of HG21547 and is suitable for raised face flanges that comply with ANSI B16.5, SH3406, HG21592–21635. 2. The thickness of blind plates, gaskets, and figure-8 blind plates already includes a corrosion allowance: Carbon steel, low-alloy steel, low-temperature steel – 1.3mm; Stainless steel – 0.5mm. 3. This series is suitable for flat gaskets; if other types of gaskets (such as octagonal gaskets) are used, it is necessary to consult the manufacturer and adjust the thickness accordingly.
