Labelling flow direction

[Stefan2211]

Dear All,
we will be supplying 16 piping skids from German supplier to US. The piping in the skid is quite congested and labelling acc to ASME A13.1 is difficult as the label for 3" pipes should be 2" x 12". This does not fit since there are almost no straight pipes allowing such long label to be fixed on the pipe. Is is common practise to use a 1" x 8" size instead?
Thanks for any input.

Wow, never even knew there was a standard for it.

If inside, use tape. If outside consider painting one on.

Flow direction arrows are very useful, but by no means universal and after a few years the stickers fall off or some idiot just paints over them the next time they all get painted...

so basically do your best and don't sweat over it....

Little inch,

here some info....

The keys words are "should follow" and "recommend labelling", which I whole heartedly agree with, but you need to be practical and follow it where you can.

the key aim is to impart information so even abbreviations such as CWR or CWS is better than nothing.

So if it won't fit, use the next size down and just note it or send in a TQ or and RFI or something with a recommendation to use the next size down.

If it doesn't fir then it doesn't fit. You're not going to redesign the skid just for that.

That's what I would do, but this is all IMHO.

oh and thanks for the info.

This does not fit since there are almost no straight pipes allowing such long label to be fixed on the pipe.

The letter size of the pipe label is typical per ANSI standard. One should be able to locate the proper space for the pipe label of the sticker type or with a backing holder mounted on the pipe.

Thank you guys. We will need to reduce the size for the 3" piping to fix any indicator on the piping. There is just no position where 12" fits in the length.

Stefan2211,

Consider reducing length via abbreviation or splitting the label into two parts before you reduce text size. One of the main reasons for the recommended size is readability of the label at a distance. If you need to split the label on both sides of an elbow, then do that over making a smaller label.

Thanks TiCl4,

That's a good idea.
