Prefabricated Piping Components

[Caphreak]

My company is interested in making small, prefabricated steam piping components (seperators and filter housings). We hold U,R, and PP stamps. Some of these units will end up in piping that is covered by B31.1, mostly 50 PSIG steam lines. What are our documentation requirements for these small parts? The largest piece is 4" NPS, and we provide material traceability on these parts, but do we need welder/welder ID records on these parts? They do not fall under section VIII because of the small size, but they could be considered small, in line vessels? Or if they are considered piping components, which have no size limitation, our responsibility for records retention increases, which will increase our cost.

Caphreak,
If you intend to sell in the EU then everything you do must be in compliance with the Pressure Equipment Directive. Have a read of the Directive it tells you exactly what documentation you need to provide.

Regardless of size, B31.1 If used for BEP and/or boiler proper should have full ASME Data report usually partial sent to the installer; every piece or spool shall be stamped accordingly per Sect I of the Code.
If for Sect VII-1 piping and falls below the stamped requirement, it shall be stamped and documented per your customer's requirements.

Thanks for the replies.

Its definitely not for PED, it gets used on the end of a steam service line to provide steam for food processing. It would not be section I or VIII piping. We are keeping records as if it would be installed in a B31.1 power piping line.

Caphreak,
Why do you state it does not fall under the PED? If the pressure is over 0.5Bar (which from your initial post it is) and is for the EU market then sorry but it falls under the PED.

We don't sell any of our work to the EU. If we wanted to export, it would fall under PED, yes. Most, if not all, of our sales are in one state in the US.
