Marty_G Posted March 25, 2021 Share Posted March 25, 2021 Hi brains trust. I know there are some really knowledgeable guys on here and I hope someone can give me a hand with what I need to set this set up to a BBQ low pressure LPG regulator hose. It is a Mongolian 32 jet burner I have bought to replace the current burner I use for my boil kettle. When I do a google search my head starts spinning as there are so many fitting and all in BSP and SAE threads. The image of the pipe work has: 1' pipe to 3/4' pipe adapter then a 20 mm union with 200mm pipe and a 20mm to 15mm on the end. Which I believe is 1/2" pipe to 3/8" pipe. Is there anyone out there with some knowledge that can give me the right jargon to go and get what I am after and where to buy it. Cheers. A very confused Marty.

Journeyman Posted March 25, 2021 Share Posted March 25, 2021 For a start, your conversions are incorrect. An inch is 25.4mm so a 20mm is 4/5ths not 1/2 inch. Not sure about gas pipe but in PVC the usual 2/4 equivalent is 19mm. 1/2 inch is 12mm. I'd have thought you could take the pipe into a plumbing shop or Bunnings/Reeces (if they do gas fitting) and get the right sizes. Link to comment Share on other sites More sharing options...

You may as well aske me how to fly a spaceship to Mars, being a mug salesman my knowledge of mechanical/plumbing etc is limited. I am sure someone will help you.

I have found that taking the piece, the complete pipe section an the regulator in this case, to Bunnings/Reece as Journeyman has suggested. In Bunnings you can search the plumbing section in the loose fittings area where you can try them as they are not carded. If this burner has been made predominantly for the USA market the threads could be NPT (National Pipe Thread). 1 Link to comment Share on other sites More sharing options...

No, that is not how imperial pipe threads run that is why it is so confusing. The external diameter of a 3/8 pipe thread is 15mm or close to it. They run on a nominal bore size. Have a bit of a search and you will get what I mean as they don't all go on external diameter the way metric pipes do. It is not like a 3/8" bolt the diameter of a 3/8" bolt is 3/8". It is really confusing. 1 Link to comment Share on other sites More sharing options...

Marty_G Posted March 27, 2021 Author Share Posted March 27, 2021 (edited) I got the Mongolian burner set up. I think 320,000BTU is a bit of overkill. After careful consideration I will rethink my plans. Oh and that is not my brew kettle that is my 20 litre HERMES coil. My brew pot is 70 litre video-1616886124.mp4 Edited March 27, 2021 by MartyG1525230263 Link to comment Share on other sites More sharing options...

I have a ~50cm high x ~50cm diameter pot and the flames fly up the sides of it. To use it I would have to manufacture some sort of chimney to direct the flames and i just don't have enough height. Those flames were about a metre high if not higher. It is not fit for this purpose that is for sure. 1 1 Link to comment Share on other sites More sharing options...
