High Performance And High Pressure ASME Lens Gasket

SpecificationsGinseal Ring Joint Gasket / Lens Gasket (JSG-RJL)GINSEAL lens gasket is a line contact seal for use in high pressure piping systems and in pressure vessel heads. The lens cross section is a spherical gasket surface and requires special machining on the flanges. Since the contact area is very small and gasket seating pressures are very high, the gaskets will seat with a small bolt load. Normally the gasket materials should be softer than the flange. In ordering lens gaskets, complete drawings and material specifications must be supplied.Lens GasketsItem No.: JSG-RJLLens gaskets are normally used as high-pressure gaskets.Lens gaskets are stress-resistant.The seating area of the lens assembled in the turned flange grooveIncreases by increasing bolt load.One disadvantage however, is that under high pressure andTemperatures, the circumference of the gasket lens may bulge whichLeads to loss of initial load.Other designs are available on request.MaterialSoft Iron, Low Carbon Steel, Stainless Steel 304, Stainless Steel 304L,Stainless Steel 316, Stainless Steel 316L, Stainless Steel 321, StainlessSteel 347, Stainless Steel 410, Aluminium, Copper, Brass, Nickel 200,Monel 400, Inconel 600, Hastelloy B2, Titanium (see more informationIn our products catalogue)Marking (standard):- Manufacturer- Nominal Size - Pressure Range- Material- Manufactured to (standard)Further materials available upon requestSpecificationsWe deliver according to the following standards: EN 1514-2, 12560-6 Suitable for flanges according ASME B 16.20, ASME B 16.47 Series A, ANSI B 16.5, BS 1560,BS EN 1092, DIN, JIS and NF
