ASME III Division 1 NC-Service Level requirement

This seems regarding the "boilers" or "pressurized vessels" since the pressure is on sciene. If so then;

1- Rated pressure means the pressure that the boiler or vessel will operate continually under.

2-Operating pressure is same as rated pressure. Design pressure refers to the pressure that this vessel can stand for.

3-I'm sure there are more regulations. Say regarding the materials used during construction, welding methods, isolation materials, ...etc.

Again, these are all for that if the ASME III Div1 is regarding "boilers".

Good information Lawrence , many thanks.

Dear All

Thanks for your kinldy response. Could you tell me the specified section in ASME III regarding definition of Service Level.

I noted your response. However, i need exactly section to apply it to Piping Design for offshore. Your kindly reply will be highly appreciated.

Thansk,

Dear friend,

I have got the part of Code titled main steam safety valves only. Subsection NC-3658.3 of the Code is concerning bending and torsional moments of the pipes that i have no details.

I think you'll have to buy this part of Code from asme.org directly. I must say that i can not help more, excuse me.

Best regards

Thanks for your kindly response.

As i understood, Service level limits are specified in NCA-2142.4. However, engineer shall understand supplementary limits in ASME III according to the cases.

Thanks,

Sincerely YT Ahn

I agree.

Interpreting NCA-2142-x may be imaginary without NC-3658.
