Gas hose

I have bought a new hose for the gas bottle and I am worry about the hose manufacture date.

The information in the hose is:

EG BS3212 : 1991/2 - 8 mm / HIGH PRESSURE LPG / NOV 00

Is this hose ok?

Thanks
 
Just wondered...

...are you using butane and is your regulator separate from the bottle? This is my setup and the pipe from bottle to regulator is 5mm although I have 8mm between a copper run after the regulator and the cooker.

Not sure if this is relevant or even correct as I have just replaced what was already there. Got mine from a Calor Gas centre at around that price.

Regarding dates, according to the recent PBO article (Jan 2002) British hose has a manufacture date while European hose shows a replacement date.
 
There was discussion on gas hoses the other day on the forum, about using armoured or non armoured. I've got to replace mine so what was the final outcome
This is the hose from the tap to the cooker yes?

'British' (usually orange colour) hose has a manufacturing date. Check it because the stock in many outlets is already out of date! (the hose will be fine , but the insurance or the French may disaggree).

European hose ( typically white) has a 'replace before' date about 5 years out .
....again check it is not out of date. This tends to be rather more obvious to the French.

In my experience, the white hose tends to degrade faster than the red.
 
Re: Just wondered...

I use butane and the regulator is screwed to the bottle.

The hose is orange and there aren't reference about were was made.
 
Not only was yours cheaper but also younger mine was dated 97 and this was unwrapped in front on me from a fresh roll?.
Evidently from what I gather from the answers from my post on the same subject. It is legal to use rubber pipe between the bottle and copper pipe run and between copper pipe run and cooker, but the limit on the rubber pipe length is 1 metre and it should be kept to a minimum. Evidently armoured cable is impossible to inspect and the regs require pipe to be replaced if on inspection it is found to require it!
Also some regs about pressure drop so do not restrict the flow as one post suggests he has by using 8mm and 5mm this may be illegal if it results in a greater than acceptable pressure drop at the burners.
In any case the regs were for inland waterways not sure how us salties fit in to the scheme of things. Has anybody had there boat checked by the BOAT SAFETY SCHEME yet perhaps they may have more details.
Shame about my pipe only being valid for this year!
At least it was red.
All the best

Do not know anything about rubber hose specs. but would it not be better to install a more rigid pipe, say copper? there are also positve connections available to connect to both the bottle and the cooker/burner.
A soft copper coil should be easy to thread through bulkheads etc. so I do not see any problems. Your local Plumbing merchant would be able to able advise.
As far as testing the installation I would strongly suggest that you get CORGI qualified engineer to test and certify the installation, including ventillation and safety alarms.

Hi Trevor

Not sure if it restricts the flow having 5mm before the regulator does it ?(desperately trying to remember his A level Physics!). Like I said I just replaced what was there with new of the same type. Certainly the connectors from bottle to wall block and copper to cooker wouldn't have accepted anything different.

Your comment has made me think I should get someone qualified to check it over though.
 
Hi Gavin

Physics books are in the loft best place for them!

Sorry when I said Gas Bottle to copper pipe that should have read regulator to copper pipe. My regulator is on the gas bottle so for me its the same thing.
You are correct due to the pressure in the 5mm tube before the regulator you will have no problem as the pressure in the 8mm tube is only 28mbar. Sorry once again if I mislead you.
The regs say if it works ok don't interfere with it, thats good enough for me.
All the best.

Re: Copper Pipe

Copper pipe should be OK for straight runs. HOWEVER copper work-hardens. Vibration will cause copper to work harden and stress fractures may occur at bends.

When you uncoil copper pipe bending it backwards and forwards more than once can cause it to harden. IMHO unless the pipe run is straightforward it is best to get the job done by a gas fitter.
 
Re: Copper Pipe date.

British pipe has the date of manufacture on it and should be replaced when 5 year old.

Confusingly french pipe has the expiry date stamped on it .
