LittleInch, thanks for the fast feedback. So for the first case MBA in mechnical engineering would be enough as you already said because of more than 4 years of study (additional to the 5 years of experience) For case b I already thought that it might be some special registration type of...

Hi, I am struggeling with the requirements as per latest revision of B31.3. We are located in Germany so I don't really understand the requirements in detail. There are 4 main criteria: (a) Completion of a degree, accredited by an independent agency [such as ABET (U.S. and international), NBA...

The reason why I am asking is that from edition 2016 to 2018 the amount has been increased from 5% to 100% VT i.e. for the circumferential welds. All our fabricated piping will be tested by third party so this will highly increase the costs. I am just wondering because the 341.4.1 (a)(3) in 2016...

Hi all, we are struggeling with the amount of VT for normal fluid service. In the latest revision 100% VT is required for all completed welds except those in components made in accordance with a listed standard. Components in that case are valves etc.? So 100% is required for all fittings...

I see you are struggeling with the same problems like I do ;) Yes and no. Could be possible that they use those paragraphs but for (a) the system must be completly identical and I see the same problems for suppliers of engineered systems which are in most cases different in piping. For (b) the...

Sure, please find attached some examples from google.. Have a look on the discharge pipes between pump and vessel.

You're correct but looks like a typo to me, because in para 2.9.3.3 refers to ASME B31.3 and not ANSI. (The references para 1.5 also shows ASME, not ANSI) Nevertheless it is required as per para 2.1.12 to keep piping loads into account even if you do not follow any kind of piping spec... *edit...

Ah okay, now I got it. I think it has nothing to do with the program itself. Maybe a big company made a decision to use it and small companies start to follow. I have never used CaesarII but some calculation companies I know in Germany prefer Rohr2 when they are free to use what they want. I...

Hi guys, I am wondering about the design of most suppliers for API Pump skids especially API 681. In most cases it is required to keep pipe length as short as possible for a good process. When you hit the google search you can find a lot of examples for those pump skids with Vessels, HX, etc. Do...

Check out Rohr2 by Sigma (german company). Seems like this will fit most of your requirements. Attention: When you also do business in oil and gas market it may be required to go with CaesarII because this is common used and sometimes required to use per project specification.

Hi all, Is there any reference in the B31.3 regarding the code to follow for the structural steel for the pipe supports or are we free to use anything we like? I saw a reference to AISC Manual but not for structural steel. For wind and seismic ASCE7 has to be followed. The information I can...

Hey guys, we often get the question from customer side if we have dynamic loads coming out of the pump to the foundation. Normally we say the dynamic loads are negligible in contrast to the static weight load because it is a liquid ring machine and not a reciprocating machine. Even the process...

I just had a look on the same website some minutes ago and I got the feeling that this topic is not 100% clear at all. Sure, the pipe stress engineers of the plant want to have acceptable loads so they can do their layout but I think its not that easy to define when you have a clear interface...

Hi guys, my company is fabricating equipment with piping on it (pumps and max 10 m of piping) acc. to e.g. ASME B31.3. Normally we go with an anchor point directly at the Tie-In point to have clear separation between our side and the customer side. Often the customer asks for allowable forces...
