Toms top tips from than award :-)

"when you test with water, the water is pushing the air against the fittings, so you are testing with air anyrode,"


See 2nd page of link above;
"2. Release air from all the high points systematically through the system to completely fill it with water."

Take it up with the CDA if you disagree. TSHW.

 

"no one gives a *".

Yes , yes , YES !!!!! Thats wot I've been saying for ages now :^O :^O

"Hahaha, this is your best one yet, if that hit you on the rze that would really really sting. It's not likeit's an anchor chain snapping ya daft *."

If the end whipping around has the fitting on it, it would do serious damage. You didn't anticipate that one though, TSHW? I did; I've seen it happen.

Not on a domestic central heating system pressurised with a footpump you haven't.

See the third page of the link posted above;

"Check that all flexible connections between the compressed air supply (or pump) are securely fastened at both ends to prevent ‘whipping’ should one end become detached."

That paragraph refers to a pneumatic leak test, at a maximum of 0.5 bar, which is to be followeed by a hydraulic pressure test.

If you disagree, discuss it with the CDA; I'm not interested in what you do, so long as it's nowhere near me or mine.

So, we can conclude: provide the impact is less than being struck by a breaking anchor chain, then it's ok.

Should the resulting impact be greater than this, then thankfully "no one gives a *."

Sorted then.

 

First, it is not copper pipe, it is tube. Calling it pipe marks you as an amateur.

onetap refers us to "Pressure testing piping systems" from the UK copper board which makes several references to copper pipe as being exactly that "Pipe"

examples on page 61 alone are.......
So should a joint, pipe, or any other

that every supply pipe or distributing pipe providing....

include a pipe made from plastics......

This is one hypocritical muppet........

 

Tube & pipe 1tap, what is the differance, tell us that rent boy??

Oh dear.
You can still buy imperial copper pipe, the main application being refrigeration systems which use US sizes and fittings as standard. So the Copper Development Association could correctly use the term tube or pipe.

UK heating and water services have been done in copper tube since 1970.

Don't you look an idiot now?

*, you got it wrong!!
Tube is measured OD & pipe is measured ID.

blowout only occurs when the tyre is run over something that creates a massive hole)

No offence Imran but a tyre blow out can occur from a number of other reasons........

Heres a few I can think off.......

1 - Overloading....
2 - Rim failure.......
3 - Cheap Remoulds used.......
4 - Over pressurizing
5 - Re-pressurizing a tyre that was run deflated.

 

"*, you got it wrong!!

Did I? Can you point out where I said it was the other way around? I must have missed that bit. One of us is wrong, but it's not me.

This bit is wrong son, you clearly didn't know the facts when you copied & pasted.
Pipe is always ID & tube is always OD.

OK son?? Stick around & learn something!!

 

"Pipe is always ID & tube is always OD."

Yes, Dick, I know.

You can apologise when you've managed to grow yourself a brain.

 

PS

I'm not called "rent boy"; maybe you have confused me with one of your friends.

 

[pedant] Tube is sized by the external diameter, whereas pipe is sized by the internal diameter {/pedant]

So eighteen mths or so ago when correcting british blue you acknowledged your own pedantry.
Yet now you use the exact same pedantry to try to score points in the current discussion.
I guess that makes you a self acknowledged pedant. Which is why this thread is so long, cos as lots of people have told you...no one gives a fck,,, apart from you and the history teacher that is.

 

As I said mantie la, he's clearly on medication.

 

LOL - And a right old pair of boring * they are too gawd , this has stretched the patience of a saint , cant beleive someone could show so much interest in something so effin boring :O

So will us pipe fitters call our selves tubefitters from now on?

You've been hufing and puffing since the beginning of this thread dissing plumbers who at the end of the day use both methods to test pipework and can do it safely.
You mentioned refrigerant systems and if you know anything about this field you would know that fitters regularly test their pipe work to 30 bar and above with ofn.
And it's often carried out in supermarket floors in the vicinity of people out shopping.

What would you suggest rent boy?
A hydraulic test?
