Crack on FRP piping
Crack on FRP piping
(OP)
Hi..
Since I dont have much experience in FRP/GRP, Is any one can share the inspection requirements for the same?
Last day we had found one discontinuity on the FRP flange looks likes minor crack..So how can I ensure the integrity or what the repair method?
Is it possible to apply lamination on flanges?
Please help me to solve this...

You really need to get in some experienced inspectors with GRP otherwise you're just guessing.
Then work out why this bit seems to have cracked - looks like uneven forces on the flange?

That's very nasty, I think You got to order the part again.

What type of inspection is used in FRP to found the surface defect.(same that of NDT in steel)
RE: Crack on FRP piping
It provides a number of photos which look exactly like your crack A14 to A17
You can actually X ray it, but the only way to make sure or get some real data is to grind off the resin layer and see how deep it goes and which layers it affects.
If it's started to break the fibres, or is more than 30% deep then you're in trouble.
Just because it isn't a through wall crack doesn't mean it's Ok. It's clearly been stressed beyond what it should have been or hasn't been made correctly
Either way FRP ISN'T STEEL, so don't look to that as a way to examine / fix this stuff. It needs proper examination by someone who knows what he or she is looking at and has seen similar things before.
This looks like the bottom flange of a vessel? Not easy to get in there to grind off some of the resin, but that's what you'll have to do.
