Hello all,
I am currently engineering a sampling system with flanged joints.
I must follow standards AMSE B16.5 and ASME B31.3
I'm using studbolts(material A193 B8 cl.2)and spiral wound gaskets in the flange conections.
In B16.5 and B31.3 I found what to use in studbolts & nuts (and wat is allowed/approved by these standards).
Can't find any mention of washers.
Am I correct to assume that ASME B16.5 and ASME B31.3 leave me free to use washers or not: whatever suits me best?
I've read some post here on washer/flange connections issues and it seems that oppions vary on how desirable a washer is in a flange conection. But standards say nothing about this issue?
I am confused, please help
(This is my first post so please inform me if i'm doing sometthing wrong)
Many thanx
