Gasket clearance for a bi-flange connection!!!
Gasket clearance for a bi-flange connection!!!
(OP)
Hi guys,
Could someone advise me on the gap that needs to be left between flanges for gasket utilization? I'm having a hard time to find a reliable source where I can obtain this info. Any suggestion? For example is 3mm (compressed) adequate clearance for a spiral wound gasket for a #600 flange? Is there a gasket type to pressure rating table with the applicable drafting clearance for a bi-flange connection.?
Respect!

If you use the torque values, assuming the proper bolting, recommend by the gasket manufacture or your calculated bolt torque values to seat the gasket this takes care of the gasket "crush" required to make the gasket seat.
