So I notice the new 34's have a combination of Stortz and Wajax couplings. Wajax for 25mm and 38mm, Stortz for 64mm and above.
The obvious difference to the current coupling system is that 38's and 64's can no longer be coupled together without an adapter, but 25's and 38's can be.
What are your opinions on this choice?
-
Must have something to do with water conservation...:-P
38-25mm good idea but at least we could use the 64-25mm adaptor on both 64mm and 38mm, restricts us a little bit more in my opinion.
Or just go the Region 7 way Barway to Wajax :-P
-
Quite simply, its retarded.
I'm not a big fan of Wajax fittings even at 25mm. Most people seem to have major issues connecting them together and trying to over tighten the couplings.
I imagine that we are going to see a fair number of 64 Storz -> 38 Wajax adaptors jammed onto the pump panels. Lets hope that CFS don't forget about the number of adaptors they are going to need.

About time they went to this set up most other state's have done it for years and it works well, I would have liked to have seen the 25mm hose removed and more 38mm hose on board,Just keep in mind that wajax couplings are only for low pressure firefighting, I have seen abrigade put wajax on their HP line only to see the coupling blow off and break...
Stortz,is good for high pressure work,boosting,hose relay pumping and so on, will also make life a lot better when we have to go interstate and work with other fire service's...CFS will now have to provide to each group that is getting the new appliances a set of adaptors for each appliance with in that group...

Don't other states use stortz for 38mm?

We've been using wajax on our sidelines for ages, and haven't had any problems yet... Seems a bit strange to go for a standard that can't take high pressure for high pressure hoses? :?

Wouldn't it make more sense to provide the new trucks with adapters to the old standard?

Yes yes yes! Can't wait to see how the storz holds up to 1200kpa and some nice water hammer, when the 38 line gets a work out. It would be good for the CFS to allow individual brigades to request their hose stowage, rather than have a prescribed number.

Some do, others don't...

Wajax on the sidelines? Are they actually HP lines or just side reels? Can you push 2000-3000kpa through them?
I thought Barway was still the standard for HP lines...?

Storz can be a pain on larger diameter (eg 100mm) as the weight of the hose/water can cause them to break their seal.....

Thats why you rig them with rope to take the weight off the couplings before you use 'em!

Ill have to re read the study CFS did. I thought they were going to Stortz for everything except 25.
Oh well.
There is a tray with a full set of adapters (not sure what exactly - but the other crew that had a look asure me its enough)
-
Storz 25mm is good stuff, does the job.
-
The internal bore of the 25mm stortz wasnt 25mm, that was the limiting factor.

The AFAC study from a year or two ago suggested 38mm and under to be 'Wajax' and anything above to be 'Storz'.
As long as they have enough adaptors to run boosters and internal hydrants, as well as to connect to other hoses, they'll be fine...

'Limiting' in what sense though? Is it enough to make a real-world difference?
-
if it puts the fire out...with less water....does it succeed at doing its job?
-
limiting is their description....

No dramas
-
as i have said before. if your using 38mm or smaller then volume of water isnt an issue. a bit of restrictiveness is not going to kill you!
-
We use our 25mm hose far more than the 38mm or 64mm...there's no way I'm going to drag 5 length of 38 around a scrub fire!! Going to 25 mm hose in my area was one of the best things we did, equipment wise.
And wajax, sorry, Forestry couplings, are far better than the original BSP couplings we had.
And how are we going to have a problem with couplings at high pressure on the bulk of the CFS fleet? Your rural, and rural / urban type appliances don't have pumps capable of high enough pressure!!! :evil:

Just the side reels, but they're about as high pressure as you'd get in the CFS...
I thought Barway was still the standard for HP lines...?
Hermaphrodite is the standard for everything now, as far as I am aware...

I don't think CFS has considered HP lines to come up with a standard coupling
for them. :?
NSW has gone universally Storz so as not to have safety issues with general
duties couplings finding their way onto on HP lines/pumps (amongst other
considerations).
Only trouble with 25mm Storz is they are very small bore thru the coupling.
Fine for low-flow high-pressure. Not so good if you want to drown something.
Not so good 12 or 15 lengths away from the pump either. :-(
-
Having a coupling standard across the board is good, but from what ive been told the new appliances are still having stowage issues as some brigades want more hose than tools and vice versa, but dont have the locker space.

<shrug> Old appliances have the same problem.
Would take a -lot- of stowage space to not have that problem !! :-D
-
Isn;t it the case of the more space you have the more stuff you carry?

Oops, better be all picky and point out Storz not StorTz... ;)

Good. Don't let it happen again, or else it'll be the cane.

does this mean it will now become standard for boosters and hydrants to have stortz on them?
-
New ones yes, current ones no....Adaptors, Adaptors, Adaptors...

Eventually yes
