Many companies in my industry weld API 2H per ASME BPVC IX, including my company for many years. We've been using the "out" that the MTRs for the API 2H plate also list A537 and/or A633, which are listed ASME IX materials. However it seems like this isn't quite right.
Should I be specifying...
In Ansys, when we Refresh Geometry on the Mechanical screen, on most of my user's computers, Ansys loses all the selected surfaces. It really sucks (technical term) to have to reattach all the connections, loads, and fixtures etc each time we iterate the design. It did not do this before when...
We're looking to make some thick-wall piping components out of A694 F60 material. The final part's cross sections range from 4in to 9.5in. Top spec is API 17G.
We're considering forging & then rough machine the part to have surfaces within 1/2" of the final part. Then heat treating (Q&T) to...
Update - after a good debate here we decided to make the wireless failsafe, with a bypass on the main control panel. The bypass completely disables the wireless control, yet we can still operate the equipment should the wireless controller be out of service.
I am still curious if wireless...
jraef thank you. No this is not an ESD; we're a separate system from the facility. An ESD would cut power to our equipment.
You're 1st paragraph is spot on with my concern - is there a legal or otherwise requirement for the term "E-stop" to be fail safe? I want to know if we can or should...
Could one of you point me to the right code / rule regarding wireless E-stop functionality?
Specifically - can a button be labeled "E-stop" on a wireless remote, if the system is designed to NOT shut down on event of a wireless failure? I am not seeing in NFPA 79.
I ask because the other...
Thanks fellas. Yes industry standard appears to assume compliance with A370/E23. Thanks for sharing your experience, and pointing out the ASTM material specs include above.
So for other materials ie 4130 (not astm), now my issue is whether I leave "Charpy test per ASTM A370..." as a...
My governing standards for many of my projects require Charpy testing per ASTM A370. (Per ABS rules, DNV rules, ASME, etc).
However, nearly all the MTRs for available stocked material, that include Charpy results, do not list which standard the Charpy testing was done under.
So far this has...
Fwiw, we use chrome plated stainless steel, due to the porosity of the chrome plating. Carbon steel base would rust in our applications. I have not used TC before, but apparently porosity is a factor.
