copper crimp type fittings

[Billy Bob Bob]

seeing lots use them on the fb groups,cant any of them solder?whats the big attraction? i guarantee a correctly done soldered fitting will last longer than something with a o ring in and fittings for this crimp stuff are double the cost,i dont get it?

 

[gasmanrob]

We use them nearly everywhere.

Hot works permits are hard to come by and I can probably crimp 10 fittings in the time it takes to solder 54mm.

Domestically I don't understand it but on larger setups it makes sense

right i can see the point in commercial works now,is a hot works permit something to do with insurance risk?

Absolutely. Hot works pins you down to a two hour fire watch after any flame or heat producing works.

Pretty much it covers gas torches, grinders, cut off saws etc some sites have dedicated hot rooms but for soldering that's not practical.

It's carp really I've got a generic non specific RAMS that will get me a permit most places. It's all about making sure the individual covers the arris of the multinational and that in the event of a disaster the multinational can put all the blame on the individual

I love crimping, it's fast and tons cleaner than soldering.
Soldering is cheaper though.

I've found that with soldering or crimping the job costs roughly the same.

The main difference is that you give more money out for materials with crimping than if you solder.
It's a catch 22 situation - it depends on how much money you want in your pocket at the end of a job.

am on a small commercial unit job at the moment where its crimped high level stuff all well and good however!!!!!!

The other day i had to do an under sink water heater and even tho we had a mini crimp getting it in the cupboard to crimp was a nightmare especially once a lot of the pipework was in.

It gets even worse if you accidentally squeeze the trigger and you pinch a fitting wrong you end up cutting out huge chunks of your work just because you accidentally got it wrong .

I still prefer solder

Crimp crimp crimp all day long. The job I've just finished was 108mm copper heating main crimped in 10 seconds and onto the next fitting. Been using they system on SS, carbon, copper, Mepla for years.

I wouldn't personally use them in domestic though - a combi swap or similar you probably wouldn't benefit from using it.

As said though commercial wise it makes me life a lot easier Ref: Hot works permits.

 

[Whyme]

On commercial we use them 54mm and above. Not sure i'd fit the crimp gun under a bath though.

solder for me every time on domestic sized work unless its a special property
