Considerations for qasket material selection:
S ize:
Thickness, thinner gaskets are recommended. Gaskets larger than sheets must
be dovetailed.
T emperature:
Peak and continuous. Refer to the PxT chart for recommended, caution and technical
advice values.
A ppllcatlon:
Factors such as safety, accessibility of joint and installation procedures affect
gasket selection.
M edium:
Refer to the chemical reference chart paying particular attention to steam,
oxidizing agents and purging medium.
P ressure:
Operation design and spikes. JMP offers technical assistance on non standard
flange bolting and surface finish.
