Hello friends,

I want your guidance please,
Sub: Bolted cover joints [Pressure vessel] to reduce cover od.

While I am designing a cover joint for pressure vessel with reference to ASME VIII, the bolting area required increase for L7 when compared B7 material, since allowable stress of L7 is less when compared to B7.

Is there any better material which can replace L7, since B7 is not used for low temperature application?

Thank you

BCR Aluminum -12, used in the navy Alaskan fleet. Don’t use copper or steel… L7’s min is 04, beyond that is dangerous. Search BCR company, for listing.
