Plastic coated copper gas pipe

[webcraft]

.
Talking to a guy who installs gas on boats today and he said the thing to use it copper pipe coated in plastic, and create a continuous run from the locker to the cooker.

What size do I need (Camping Gaz installation) and where is the best source? I believe there are metric and non-metric sizes?

Plastic coated tends to be used where it in cement, as the copper corrodes in contact with cement.
As to sizes, 3/8" or 10mm is fine. Even 8mm.

Yorkshire copper sell it to merchants (but not to small individual customers) and have some useful technical information - see http://yorkshirecopper.com/wp-content/uploads/Technical-Guide-full-issue-02_14_Really2.pdf.
My understanding is 10mm is preferable for cookers with 3 or 4 rings plus a reasonable size oven.
Recently bought some (yellow covered 10mm copper tube) from a person who had some left over from a gas installation on a Beneteau 473.

It's readily available from suppliers of Autogas (LPG) equipment. The last lot of stuff I got, including coated pipe, came from LPG Parts, who have an eBay shop at http://stores.ebay.co.uk/lpgparts. Cars generally use 6mm for the supply to the engine and 8mm for the filler.

You might also be able to find it locally. Soroba Rd filling stations sells LPG and I wouldn't be surprised if there is someone in the area who converts 4x4s for the farming community.

This is a standard two rings and oven boat cooker, 8mm should be enough and will fit standard fittings?

He gave me the same advice, I assume it is the same bloke in the area, but after seeing hidden damage to copper pipe I decided to run a new line that is not coated but visible over it's whole run. I used clear 20mm plastic pipe at various places to protect the copper pipe and used the rubber coated pipe clips.

The previous run on my boat was 8 mm for a 4 x ring and oven cooker, about 7m run in total, so 8 mm should be okay for your run, but not less than 8 mm. You can all sorts of converting pits and pieces to suit the fittings on the cooker. Keep the rubber pipe to less than 1m and fit a pressure test point.

I originally planned for a bubble tester and Clease valve but decided to remove as much as possible and just use a marine regulator. If you want a new bubble tester / Please valve PM me.

My original copper pipe was 6 mm feeding a two ring cooker, grill and oven, plus a catalytic heater. There always seemed to be sufficient flow but I replaced it with 8 mm as parts were difficult to obtain.

SOCAL sell everything you need...

5/16" or 8mm will be fine. I seem to remember that they are so similar in size that the fittings for one size can be used for the other.

Absolutely - gas pipe needs to be easily visible for inspection - speaking as someone who learned the slightly hard way, when I bought a boat with metal sheathed flexible pipe to the gymballed cooker which ruptured leaving a vertical jet of flame at the back; the SECOND word I yelled was ' Fire ! '

Nowadays I can't believe I was stupid enough to trust existing flexible tubing, I replace that every season now ( caravan shops have the same stuff, date printed on, at a fraction of chandlery prices ) and the copper pipe is one length with no joins, to the also annually replaced flexible bit to the Marine ' M ' class regulator - which is only turned on the moment I use the cooker, and off straight afterwards.

I have a 129hp car engine which is kept amply supplied with gas through a 12mm ID pipe.

My last BMW was fitted with a BMW gas installation and had also 12mm pipe.

I got some 8mm cupper plastic coated pipe that I am thinking of using. I’ve heard good arguments for and against. My thinking is that having it coated prevents corrosion if the plastic coating is kept in good working order i.e. no nicks or damage.

There is a slight difference between a car installation and a boat with a little 28mb regulator. I installed some chinese wok cookers and the standard commercial two stage regulators on the installation could not keep up with the fierce burners. It was quite difficult to get the flow and stay within the rules. The car bits allow greater flow.

My 28mb butane powered domestic cooker (4 rings plus oven, standard small domestic kitchen type) works fine on 8mm, so for your installation, yes, 8mm or 5/16". SOCAL have plastic coated and plain pipe and all the fittings.

Bear in mind that some plastic coating is a loose tube and fluted (?? grooved) inside, as one homeowner found out when the oil leaked outside the house, ran along the fluting and exited inside the house.

+1 fortunately for me it didn't end up inside the house, but I would definitely draw a difference between a plastic coating sealed directly on the pipe with the fluted type. Apparently, that type is commonly sourced from refrigeration suppliers.
