Seals Bx Lens Ring Joint Gasket
BKG-1102 Ring joint Gaskets are machined from variety types of forged solid metal such as soft iron,ANSI304,ANSI316,ANSI321 metal or other alloy metal.they are designed for high pressure and temperature or high corrosive applications with suitable shape and material. Ring joint gaskets seal by an initial line contact or an edging action as the compressive forces are applied. The hardness of the ring should always be 30-40HB less than the Flanges hardness to prevent flange deformation.Dimension of standard ring joint gaskets and grooves are covering ASME B16.20 and API 6A, API 17D and ASME B16.5/B16.20.
