Gas pipe in Kitchen

[jassdhali]

Guys,
Just a query, been digging up my kitchen floor for new concrete base and insulation.
I have come across my gas supply pipe from meter to hob. The depth of the pipe is 110mm. This would place the pipe smack through the middle of my celotex insulation.
Question is should I get the pipe re-routed or is it okay to run it through my 100mm insulation slab.
Thanks

Are there any joints that you can see?

Hey,
There is one 90 deg joint/reducer looks very old and quite thick.
Thanks
