Qual oil pipe

[SJB060685]

Quality pipe always a no no above ground. Only carry 10mm pvc coated copper. The copper is cheaper as well.

Agree totally mate. We only ever used plastic coated copper. Even the smallest domestic installation probably has an oil tank close to 1000ltrs. If plastic pipe was installed wrong and failed on a gravity system then there will be a hefty clean up bill.

needs to be 15mm as it’s over 12m so best part of £230 for soft

Quote up 12mm pipe? Even if you can't get plastic coated you could lag in some electrical conduit.

can’t get locally and tbh never seen 12mm

that was my thought 2 6m lengths of 20mm galv conduit just emailed qual to see there stance on it

Let me know what Qual say about above ground usage please. I'm certain it's a no but they might know better.

 

[ShaunCorbs]

I will I can’t see why in theory but there’s two possibilities

one mechanical or environmental damage

two fire risk

BES.co.uk do table x half hard copper in 12mm 3m lengths. Possibly find longer if you looked.

"Qual-Oil pipe is for below-ground use only. BS5410 was amended in March 2001 to include thermoplastic oil lines, which are approved by OFTEC, for below ground applications. For above ground applications metallic pipe must be used."

So, perhaps the answer to the paradox is that it's UV stable enough to store outside (for some unspecified length of time) but it can't be used above ground due to a prohibition in BS5410.

Still don’t know any half sunk tanks but I bet there’s one

looks like it’s 15mm and couplings

 

[SJB060685]

So there you have it. NOT suitable for above ground usage.

Yep and you can’t go from the tank to the fire valve without joints

 

[SJB060685]

So you would need the fittings at tank valve and strainer, then couplings, then your run of Qual pipe, another coupling and then your isolating valve, filter and fire valve before continuing to burner. Even if you do the iso valve, filter and fire valve properly with bushes and not multiple compression fittings that is a lot of potential leaks. Also any joints below ground need to be done properly as well, 450mm depth, a base of sand above and below oil line and marking tape 150mm below ground level to show a join. I'll stick to copper thanks lol.

 

[ShaunCorbs]

Correct too many joints for my liking underground also you couldn’t flare it so there’s that

or fit a Tiger loop then it’s 100m

 

[SJB060685]

Just remember if you're not flaring it you need inserts for compression, in case you didn't already know.

tbh wouldn’t risk it underground run a new line

 

[SJB060685]

Exactly. We never experienced a major leak but I know of many horror stories of either oil tank fires, or hundreds of litres lost to the environment. The environment agency will blow their lid if it was proved you were responsible for such a leak. Thousands in a clean up bill.
