MDPE Gas Pipe

[pte440]

Hiya,

Can anyone confirm if MDPE gas pipe must be buried or used outside?
I am looking at a run of about 60mtrs of 50mm pipe through a roof void, i have had 2 quotes, 1 for tracpipe, 1 for melleable iron.

Any thoughts please?

Peter

my thoughts are why not copper? and the guy quoting tracpipe only intends to use a clip at each end

50m of 50mm thats why not copper

MDPE must be buried and to the required depth and cannot be used internally.
Use the tracpipe or steel.

1 for melleable iron.

no plastic in properties.

Depends on the building and it's use.

Industrial would normally be steel on hangers.

The RGI must also have a commercial ACS for industrial pipework, purging and testing.

MDPE gas pipe must not be installed in or under ANY type of building.

Would need welding, so pipefitter/welder required.

personally i'd fit tracpipe on tray and hanger.No joints except transition will probably work out cheaper.

No it wouldn't, 2" can be screwed.

21/2" and above should be flanged or welded.

Sure my copy of up2 is 50mm and above.

I'll have check now.

 

[Biggles..]

my stupid mistake.

less than/equal to 50 is screw/weld

above 50 is weld.





would still use tracpipe and tray though.

err we have all done it
