Scope
This document specifies the requirements for gaskets used on large-diameter steel pipe flanges, including their inspection, marking, and packaging, as well as their transportation and storage.
This document applies to large-diameter steel pipe flanges with a diameter of DN 650 (NPS 26) to DN 1,500 (NPS 60) and a pressure rating of Class 150 to Class 900. It covers the following types of gaskets: winding gaskets, metal wave-toothed composite gaskets (hereinafter referred to as "wave-toothed gaskets"), metal serrated composite gaskets (hereinafter referred to as "serrated gaskets"), and non-metallic flat gaskets with a pressure rating of Class 75 to Class 300, as well as flexible graphite composite reinforced gaskets (hereinafter referred to as "reinforced gaskets").
