Indicating media blast on a portion of a cylindrical surface

[TeejT]

I have a stainless steel cylindrical part. A portion along its length needs to be media blasted with aluminum oxide. How do I correctly specify the limits (end locations) of this section that will have the media blasted surface? I'm using ANSI...
Thanks in advance!

I'd add in phantom lines or similar and dimension to them (& possibly hatch the area to be blasted) and have a flag to the note that details the blasting.

Or am I missing part o the question?

KENAT,
I don't think you're missing anything, but I don't want to improvise. I need to know what the correct way to identify the portion of the surface would be per ANSI. By phantom lines you mean construction (dashed) lines?

Take a look at ASME Y14.5M-1994 1.7.3 (and sub sections) and figure 1-11. Technically the line type is 'Chain Line' and for you application you probably should hatch it with 'section lines'.

The same in Y14.5-2009 is shown in fig. 1-13. Paragraph number (1.7.3.) stays unchanged.
