Temporary Repair calculations for piping

[mariolucas75]

DEar All,

Could you please advise me please any link / resource where i can find examples of piping composite wrapping (temporary repair) calculations ?
How many layers depending of piping / fluid parameters ... In fact PCC-2 practical application examples

Tank you so much

Is there nothing in ISO 24817 to support?

I think this is more of a vendor dependant thing than a calculation per se.

What are you trying to calculate exactly and why?

Composite wrap is only for non through wall thickness corrosion.

I will suggest you to look to the book ; Rehabilitation of Pipelines Using Fiber-reinforced Polymer (FRP) Composites by Vistasp M. Karbhari

If you write ' Rehabilitation of Pipelines composite ' and search the web some of the outcomes ;
www.compositerepair.org : there are useful articles at this site

See the latest PCC-2. There are entire Chapters/Articles devoted to temp pipe wrap design.

Composite wrap is only for non through wall thickness corrosion.

There were some perforations pin-hole leaks in piping and to calculate number of wraps depending what wrap it is ....

AFAIK, composite wreaks are not designed for through wall defects.

You needs a metallic clamp or sleevev. Or cut put.

Write ARAMCO SAER-6061 and search the web , one of the sites https://1filedownload.com/category/api-asme-resources/page/28/
and the outcome is the following free document .

Just for sharing the knowledge ..
