Use a 6V7059 Micrometer to measure the thickness of the flange.
Measure the thickness of the flange with a 6V7059 Micrometer. Use the liner again only if it is acceptable according to the specifications in the chart below.
Liner with significant erosion/corrosion in filler band area, under liner flange and in fillet radius (crack could be hidden by glass beading or by improper cleaning) – Do Not Use Again
Liner with nick on the bottom of flange – Do Not Use Again
Damage to the fire dam. Use Again only if the damage is not extended completely across the fire dam and any burrs or sharp edges are removed.
Damage in the gasket surface area. Do Not Use Again.
Nick in the vertical flange edge. Use Again after any sharp edges or high areas are removed with a file.
Chip in the seal edge of the flange. Do Not Use Again.
Rough, pebbly surface extending in a random pattern. Do Not Use Again.
Pits and fretting under the liner flange. Large pits or groups of pits are not acceptable, especially in the radius. Do Not Use Again.
Fretting is acceptable when it is circumferential and does not prevent the liner from sealing. Measure flange thickness. Use Again.
