took 2 months off from job, and got some progress.
Fittings arrived, and 2" pipeline started to grow.....though working with that pipe diameter a lot harder then I originally had thought.

Bought a power pipe cutter, very nice investment. Couldn't be more happy with that, but electrical threader is disappointing. I prefer a manual one.

I would return the galvanized fittings and exchange for black, it's not really what you need in a hydronic heating system.

Thanks, I didn't know that.
Will galvanized fittings course rusting?
I couldn't find black unions, they are all galvanized in our store.
And I couldn't find suppliers who send items to Canada.

Yes, the project has to completed in 2 months, I took pandemia holidays.
The most difficult part- replacing underground pipelines. 300' in one direction. At the same time I learn MIG welding.

There is a risk of hydrolysis but probably not a big one due to the dissimilar metals. The other issue is the galvanized flaking off. And that depends a lot on how it was applied, either plated or hot dipped.

It can and does work but generally it is avoided.

Ок, I will put another Y strainer just before pumps to filter out these flakes. Thanks for the advice.

My first welding job done today. I never done any welding before, learn welding mostly from YouTube videos.
Liked this one

But I couldn't fit 4 layers as they say, managed to weld 2 layers only. Root +top layer.
Used 70 amp, wire 0.8 and argon +CO2 mixure.

May pay dividends to do periodic leak checks during progression of welds, repairs will be more than just inconvenient.

So why didn’t you just use thread-o-lets? Or buy a pre-made header?

There are two reasons why I prefer welding.
1. The most important -I need to become confident with welding, in couple of weeks I gonna start welding underground pipelines. So, I need to learn before I start.
2. The second reason.
I have got a tonn of different pipe fittings from a factory, almost for free. I paid around 50 cents per each. And unfortunately they are not threaded.

Right, now I am kinda confused, shell I weld just only one layer with bigger amperage, or better do root first , then top layer?
I have 2" and 1-1/2" pipes.
I weld everyday a little, and weld looks better and better, so, I have a progress, and I love it.

What is the best way to check these leaks? System isn't completed yet (loop is open).

I am installing unions as many as possible and coupling them with ball valves. In case of leakage system can be separated, and fixed.
