Hi all, Thank you for your comments and apologies for my delayed response. @LittleInch - yes we will have an operating pressure - a specific back pressure generated form the air distribution nozzles. But this will be nowhere near the full design pressure of the system. And by "more relaxed...

Hello everyone, Was hoping someone would be able to help me with an issue I have. I have a pipework system which is essentially open to atmosphere. Its an anti ice system. Hot air is passed through a manifold and through a series of risers, then passes out into the airstream of a gas turbine...

Roby, Thank you for your input. It ties in with XL83NL's post as well. XL83NL, Thank you for your detailed response. It gives me the confidence that it can be done. Also, thank you for referring me to the CEN/TR 14549 code, I wasn't aware of that. I will get my hands on that and review...

Hi LittleInch Thank you for the response. We are looking to design the piping systems to ASME B31.3 and looking to use pipe, flanges and fittings called up from ASME B36.10, B16.5 and B16.9. I have completed PMA's in the past to confirm conformity of American material (A106 Gr B) on...

Hello, I have an issue which is confusing me a little and I'm hoping someone can help. I have 2 questions: Is it possible to achieve CE marking if you're designing to American codes - ASME? What is the stance on using ASME on sites in the EU? The site is in UK / Europe. As far as I'm...

Thank you for the quick response XL83NL. I agree that the NoBo should be providing a little more guidance on this. They have a large amount of experience with American codes and I think they just want to apply these to this contract, but I don't think that they can. I also agree with the CPR...

Hello, I have an issue which is confusing me and I'm hoping someone can help. Is it possible to comply with EN1090-1 and achieve CE marking if you're designing to American structural codes - IBC and ASCE? The site is in UK / Europe. As far as I'm concerned, Eurocodes must be used for the...

Thank you all for the feedback. Threaded connectors / pre threaded fittings is the best way to go!

Hi everybody, Apologies if this topic has been discussed time and time again – I’ve had a good search but can’t find anything, maybe using the wrong ‘buzz words’. Anyway, my question is of a pipe threading nature. Small bore pipe and pipe threading is not a strength of mine so I’m having some...

Thank you for the feedback

Thank you for the response. I will feedback this issue regarding tricky installation with regards to maintaining correct orientation of the welded components. I think a union will be the best way forward. Thanks again

Thank you for your reply. The media is only water for drainage.

Thank you for the advice all!

Hello all, I just wanted to check this with someone in case I'm missing something obvious..... I need to use a threaded coupling at one point in my arrangement to tie in with existing equipment. The connection is a 1" female thread. I am going to apply the required male thread onto my 1" pipe...

Hi guys, Thank you for your comments. They are both kind of backing up my feeling that it would be best to just buy in the equipment instead of designing our own. We wouldn't be making them in different sizes. The only involvement I've had is someone coming to me and asking, 'is this...

Good afternoon, I have an issues which I'm having trouble with and was hoping to get some advice if anyone can help...... My company would like to design its own pipe silencer rather than buy one from a acoustic company..... The concept is a 6" pipe contained within a 12" pipe and 12" end...

Hello SRE / dhengr, Thank you both for your advice. I am happy that both sets of material will have full traceability and they will have been manufactured in line with the relevant codes. I will complete my design update to the appropriate design codes, so I am happy that we will have no...

Hi all, Is there any rule or code restriction that stops you from using steelwork sections from different countries in the same steelwork structure? We have a structure fabricated using Chinese sections, but we need to do a modification / addition and it would be best to use UK sections if...

@metengr - thank you very much for the advice.

@metengr - thank you for the tip. I have done some more research around the site you recommended and F1554 Grade 105 is a 4140 material that is heat treated and is very similar to A193 Grade B7. Potentially, F554 Grade 105 could be a choice, but A193 Grade B7 would probably be better to specify...
