Ok I am in the process of helping a friend make a exhaust for a generator.He is putting the generator in a old brick shed and needs to build a exhaust pipe that can connect onto the original pipe of the generator.The exhaust pipe on the generator is 13mm and we need to connect it to a standard 15mm copper gas pipe as steel pipes are approx ?15 per meter and we need 3M.And a copper 3M pipe is ?13 so that is why we have gone for copper.But anyway He wants to connect his generator to a standard 15mm copper pipe and he plans on using reducers and couplings connected together to do this, but we cant get hold of any 12mm connectors and 13mm are too big they just side off,We really would like to thread the 15mm pipe and somehow screw it onto the exhaust pipe that is already connected to the generator.Any Ideas
You smelt it in a furnace and you can make buckets armor you make your iron tools iron doors and more you just gotta to check your crafting table
We can do process of crushing, grinding,screening,etc to get high level iron ore concentrates. After we know clearly about working flow and consisting of iron ore processing plant, we can design our plant. While these simple intonations are not enough, we need more.
Turn iron ore into iron. I think you use the furnace. Iron can be used for a lot of stuff.
And what does aluminum cost? Is there enough pipe on the generator to cool the gas so it doesn't melt the aluminum. 15 mm (or 13) seem astonishingly small for a 3m pipe on an engine exhaust - back pressure might mess up operation - ask around.
copper pipe might not be best, but I'm sure you've considered the pros and cons. It's not a huge change in diameter, so you could probably use a method that works on many car exhausts. cut some longitudinal slots down the larger pipe. When smaller pipe is fitted inside the larger, and jubilee/hose clamps are tightened up over those slots the larger pipe gets pushed tight against the inner pipe without too much distortion. applying a little exhaust paste between the pipes during construction should form a reasonable seal. If you really want a coupler, you need to identify know what type of thread is on the exhaust. I'm guessing it'll be a (tapered) pipe thread, and it may well be an imperial thread. It'll certainly be possible to get taps that would cut a matching internal thread, but in that size they unlikely to be cheep. Best find a machine shop that can make it for you. On the exhaust extension side- sounds like you're wanting a compression fitting, with an olive and nut to hold the pipe in place. Fairly simple job for a decent machine shop. If you can't find any professional machine shops will to do the work in your area, Here's a few possible alternatives Local model engineering groups will probably have the required equipment (or be able to put you in touch with people who do) and if you ask nicely they're bound to have an interest in your project, and would love to help out. Another option might be to see if there's any schools/colleges/uni's around you that do metalwork. Ask nicely and the teacher/shop foreman might be able to arrange for a student to make a practice piece that solves your problem [might make a change from turning pulley's or something else that'll never get used]
