pipe threads - tips&tricks

[brikgreg]

hello colegues

Im in HVAC buisiness as you but Im from Slovenia. I was looking similar forums in my country, but no luck so far (too small market)
Im preparing tips&tricks manual for young plumbers in area of pippe threading (water, heating, gas). here we mostly use REMS machines
which is same as anywhere. we have imperial units 1/2", 3/4"... threads are standard from DIN, DVGW so they are same as in your country

well if any of you have some useful tips for this work, or you have manual you could recomend or book or just want to say hello,
please do that

Rough up the threads with a hacksaw blade before applying your loctite/hemp and jointing compound.
Use cutting oil whilst threading the pipe.

 

[brikgreg]

thank you for your kind replys. I think its not important what kind threads you use BSP or DVGW, its technik and experience
(size dont matter roughing up threads is for better sealing, so material cut into opposite side? or just better hold loctite?, nice tip, thx Subby.
I have question if anyone like to answer -
in case you use loctite 55
how many times you wrap over threads? more than loctite says?
I notice older plumbers do that, just for extra safety

I always end up putting more loctite than it says but another plumber i work with now and again does stick to it more or less and doesn't get any problems, amazing stuff.

Putting too much loctite 55 on can end up causing problems as it can bunch and push off the thread. I use 6 turns as per the instructions and don't get leaks.
