Thank you! The full 1hr course is available for free on EngineeringTrainer.com. Check it out :)

hi there, thanks for asking. This indeed is a very relevant topic! We will run a virtual instructor-led course that covers this during the fall, you can find more and register here: www.engineeringtrainer.com/shop/vilt2201-product-pressure-equipment-directive-ped-compliance-using-harmonised-and-asme-standards-411#attr=162

Hi there, As long as cavitation doesn't occur as part of the negative pressure, the negative pressure wave (expansion wave) behaves similarly as positive pressure waves (compression waves). Except for the minus sign of course.

Hi Paulo, thanks for your question. We're not sure what free license options vendors have tbh...

Thanks for sharing, Simon!

hi Simon, interesting comment. Thanks for sharing!

Thank you so much 😀

Thanks for watching!

Hi Tony, thanks for asking. This approach presented here considers the pipe as a 1-dimensional element and assumed the pressure is constant over the entire cross-sectional inner area of the pipe.

Thanks for your comment. The answer depends on the type of SBC. For simple cantilevered SBCs like the ones I showed in the presentation, the overall length should be minimised to reduce the risk. However for SBC which connect to a fixed point or which connect between 2 different main lines, the overall length must be ‘not less than a minimum allowable length’ as specified in the EI Guidelines. This length depends on the SBC branch diameter and the type of welded fitting e.g. Weldolet. Let me know if this answers your question. Regards, Neil

@@neilparkinson119 thanks for the reply.

We agree! :)

​@@EngineeringTrainer thanks, that was just wonderful. Please give me the link of video in which you have covered the topic of comparing 1D stress limit values with 3D stress state.

Thanks for your positive note, Alejandro! Great that our work is of value to you!

Hi Jonny, in order to maintain the pressure the pipe has to be closed somewhere. The pressure puts an axial force on the pipe through blindflanges, elbows or closed flanges. This stress is dan present in the entire pipe otherwise the pipe for a force equilibrium to exist. If there is an outlet and the medium flows out then the flow resistance with the pipe causes the force necessary to provide balance.

@@EngineeringTrainer Thank you for taking the time to explain, it makes sense now!
