Can we get 2inch branch from 4inch header with Hot Tapping?
our fluid is not flammable.
Do we have any limitation for size of header and branch.
I have seen Api-2201 , but I could not find the limitation for sizing.
I want to tight the bolts of for example one 20 inch flange.
I know the bolt size and bolt material.
I have calculated the yielding strenght for bolt material.
Now what should I do?
for bolt tightening when we have yielding strenghth of bolt and nut how much we should tight?
for example for tightening of two flanges and one spiral wound gasket between them.
When we want to tight the reactor bolts , is it necessary to have hot bolting?
However for bolt tighting , how much torque we need in the cold condition ot hot condition?
