Can carbon steel be used for a non-pressure vessel application for an exhaust muffler that will see an ambient of -67F? During run, the gas temperature will be 850F. Maximum back pressure will be 10" w.c. The unit will be 30" diameter x 352" long and mounted horizontally.
I am told ASTM...

Some tell me that we have to build a code vessel and do SharpE testing and impact...

(The new units are in design so we can add more holes to the base rings so new anchors can be installed.
We will do a wind load and seismic analysis even though the pads are in place to test our customer's assumption that the old pads are adequate since the weights are about the same...

Yes, the anchoring puts the bolts in tension.
Most nuts engage all the treads so the threads are even with the top of the nut.
A few bolts are short and their nuts engage about 50% of the nut height.
The bolts are 1.25dia x 6 coarse. There are 8 per unit.
I wish I knew...
I am installing several exhaust systems, each weighing 15,000 pounds on existing pads with existing threaded anchor studs. 1.25 dia x 6.
Some of the studs are short preventing full nut engagement.
What are the best practices to extend the length of the bolts?
