gas pipe along inside hull, attach to??

[bikedaft]

hi,

reinstating gas cooker to 1971 hustler 35. there is a 5 foot wide cockpit locker to be spanned, between 2 bulkheads. i have heard of folk glassing bits of wood at the specified intervals (?6", will need to look at regs again) and screwing clips into glassed in wood. or can i securely mount a 5' piece of wood between the 2 bulkheads against the hull (all at the top/back of the locker out of the way) and attach gas pipe this way? any thoughts? either side of this locker there is plenty of wood to screw pipe clips into.

cheers...

its been here before ( do a search ) i ran mine through a reinforced hose with a hose clip @ each end, this protects the gas pipe & is almost double pipe. this can then be clipped down to a stringer or similar

Sleeve it in polythene pipe and wedge it against the hull and then glass the pipe in with small strips of tape/resin at intervals. The copper can still be withdrawn if you need to later on leaving the polythene pipe still installed. Taking the polythene pipe just through the bulkheads at either side of the locker does mean that anti-chafe elements are taken care of and you do not then need to introduce more bulkhead fittings and joints with later fail or leak potential into the pipework. For belt and braces you can run your polythene with copper pipe inside through an electrical pvc conduit which looks very neat, again projecting a few mm through the bulkheads either side and glassed over at intervals.

[/ QUOTE ] Yes! look at section 8 of chapter 7 of the Boat safety scheme. http://www.boatsafetyscheme.com/downloads/BSS_Guide_chap7.pdf
The pipe should be fixed at a minimum of 500mm intervals and within 150 mm of any joints. It should be run in gas proof conduit through petrol engine or electrical equipment spaces.

Easy enough to fit wooden pads to the boat structure where required. Car body filler seems to do an excellent job but they can be glassed over as well for maximum security.

How about a couple of pads glued on with Sikaflex 291?

Might be better to go for a length of wood though otherwise there will be a length of copper pipe standing out from the boat by an inch ir two which will be even more prone to damage than no clips at all.

That's what I did. I fixed the small blocks of wood to the hull with Plastic Padding Glass Fibre Filler - the green/blue stuff in a tube. The great thing about this product is that it holds the pad in place until it sets, even on a vertical surface. West System epoxy with microfibres would do the same and would be even stronger. Clean the hull first then rough up the surface of the wooden pads and the hull with sandpaper for better adhesion. Fit the pipe to the pads with the proper copper pipe clips.

Where the pipe went through bulkheads, I drilled an oversized hole and stuck a wooden pad close to each side so that the gas pipe was securely held in the middle of the hole and couldn't rub on the sides.

cheers for your help /forums/images/graemlins/ooo.gif

If you are running gas through a locker where mechanical damage is possible I'd go for plastic tube and or conduit.

agree, will probably go for pipe inside conduit, mounted on wood. it is out of the way right at the top of the locker, but there is a kedge anchor in there...
