The product is designed to seal the ends of a pipeline or any connection. Bolts are not included and must be purchased separately. Various sizes available: DN15 to DN200, with diameters ranging from 80mm to 320mm, and thickness from 12mm to 22mm. Hole patterns range from 4M10X45 to 8M16X70. Flanges have a primer black paint finish, which may chip or flake during transit, but this does not compromise quality. Once installed on pipework with a pump or valve, the flange typically gets painted with red oxide for rust protection. This product ensures effectiveness and durability in any application..
