Hello!
Please, I want to know if stress relief is required for 900 and 600 psi carbon steel hydrogen piping, below 390° F.
What papers or standards may focus this aspect?
Do you know inform the standards the hydrogen industries adopt?
Thanks
Hello,
I want to know which is the torque value to be applied on the base anchor bolts of pressure vessels, process columns and stacks.
Can I simply use the torque values determined for bolts considering bolt diameter and material?
Some say the correct practice is tightening the nut by hand...

Hello!
I'd know:
1- Why the ASTM A 182 doesn't show hardness values for the most of the stainless steel forgings?
2- What is the hardness value for the A 182 F 316 RTJ flange?
3- Assuming a 160 HB hardness for RTJ what is the standard flange hardness?
Thanks
Hello!
I want to know if it there is a Pultruded Components Inspection Standard or Guidance. We're started to use pultruded platforms, ladders, etc and what, when and how must I inspect them?
What is the mean life time of pultruded components environmentaly exposed?
Thank you,
