Installing steel pipe

[Mgrant]

Any one on here had much experience in installing steel threaded pipework? With a threading machine etc.

 

[Howsie]

Tiring work but quite rewarding when done right. Anything specific you want to know?

 

[kozak1968]

Yes. How can we help?

 

[nicro3]

Any specific Q need answers to?

 

[Whl4852]

Yes! Plenty!

 

[Mike Jackson]

I enjoy it occasionally but don't do enough to warrant a power threader. I just use a drop head ratchet threader.

 

[on31ll]

But the power threader seriously helps !

james has gone to bed!

 

[Whn1]

Yea we got a Rems auto threader..... heaven.

 

[Subby]

I've been known to screw a bit of iron. Fire away.

 

[Dotty]

You ever tried hand dies on 2"?

A threading machine is a godsend.

When taking the measurement for a section of pipework to cut and thread, say between two elbows. Do you measure the distance between the elbows from the end of the internal female thread of each elbow. Or does the pipe screw further than this in to the fitting?

 

[Whl4852]

Yeah from where the thread ends, and allow a couple of extra threads when you do your new piece

 

[Barry98]

All the way into the female then about another 5mm for good measure

 

[Mgrant]

so extactly the measurement from were the thread ends on the fittings?

 

[Mgrant]

If using hemp and paste for heating pipe work do you put paste on then hemp then abit more paste?

 

[Barry98]

You can't use hemp

 

[tamz]

You can use an old pair of ripped knickers on heating if you like.

 

[Whl4852]

Use ptfe mate

 

[kozak1968]

Use a tape measure to measure inside the fitting then you will know how far to screw in.

 

[Dotty]

You can use hemp on heating pipework. Not gas.

 

[Barry98]

That's what I mean , had a doo at a prison I did work at with the gas safe inspector last year

 

[nicro3]

As a rule of thumb use c-c measurements then subtract c/line of bend to back of thread. The norm is leave two threads showing when joint is fully home, then clean of excess hemp. Hemp then jointing compound is the way I have always done it.
Make a few bits up and you will soon get in the swing.

 

[Mgrant]

All the way into the female then about another 5mm for good measure.
Is that because the pipe thread can screw in further than the end of the thread in the fitting?

 

[Whl4852]

It's just so you can see which way the threads go, ease of use, best practise. What's the project anyway?

 

[Barry98]

No I was just taught this , it's just incase your slightly out it will save having to undo and recut again taking time

 

[Barry98]

James where you based

 

[Scott_D]

Add 1/2 an inch for 1/2 inch pipe and 3/4 of an inch for bigger pipe to go into each fitting. Depends how long you cut your threads though.

 

[Mgrant]

Based in bradford. Is re-routing a central heating pipe due to it begin in the way of a were a new door way is to be put.
