    Welding API 2H per ASME BPVC IX

    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, Refresh Geometry from Solidworks loses selected surfaces. Help!

    If anyone else runs into this - upgrading/updating to latest version of Windows 10 fixed the issue.

    In Ansys, Refresh Geometry from Solidworks loses selected surfaces. Help!

    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...

    Thick wall A694 F60

    Hence the question asking if someone has experience with this.

    Thick wall A694 F60

    Thank you. Yes I had found those; they only go to 4" thick. My finished wall is 9.5" thick, 10.5" thick at heat treat.

    Thick wall A694 F60

    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...

    Wireless E-stop required functionality on loss of signal

    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...

    Wireless E-stop required functionality on loss of signal

    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...

    Wireless E-stop required functionality on loss of signal

    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...

    Mill MTR charpy standard

    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...

    Mill MTR charpy standard

    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...

    SSAB's weld engineers are very helpful.

    Analysis of a Welded Structure.

    We run all our weldments as one body. Gets a little tricky to put the gaps in behind fillet welds. But once modelled, FEA gives good results.

    Autodesk Simulation Mechanical VS Ansys

    We use Ansys for all above; has handled everything well. Hardest part is managing the licenses! Can't compare to Autodesk product.

    TUNGSTEN CARBIDE COATING

    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. http://www.carbidetechnologies.com/questions.php
