Pipe Thread Compatibility etc between USA and UK
Pipe Thread Compatibility etc between USA and UK
(OP)
Hi Folks
Tucky here
Still working on the holiday resort job in Antigua
Just a thought,--- can anyone tell me if the equipment used in the USA/Antigua area has compatible pipe threads, flanges etc as we use in the UK
We use metric (although we still refer to 1" pipe, 2" pipe etc, but we also refer to 25mm pipe, 32mm pipe etc)
Also is the soil pipe (foul drainage waste) the same standard. We use for instance PVC pipe which we call 4" and this is 110mm diameter.
My point is, if we export equipment from Europe, will we be able to marry the equipment together if we use locally purchased materials.( or do we ship over the pipe and fittings, or do we buy equipment locally)
The last thing I want is to send a boat load of hot water cylinders across and find that the local pipework is not compatible with European standard sizes.
Can anyone point me in the right direction please.
Tucky
PS
If the answer is...Use local pipe,fittings and equipment, then I will need to know who can supply the following:
Solar water panels and solar storage hot water cylinders, Rain water tanks and controls, Reverse Osmosis water treatment plant, fire sprinkler systems for commercial and domestic systems.
Thanks

Take the "V" out of HVAC and you are left with a HAC(k) job.

I don't know what they typically use in Antigua. I get the impression that in most of the Caribbean, anything goes.
If there's a yacht repair yard nearby, they might have, or have a local source of, any adapter fittings you might need ...
or they might rely on my second suggestion: your hometown Swagelok distributor and Fedex.

Check what the local supply houses stock for pipe & fittings. The European equipment manufacturers should be able to provide detailed info about the piping connections on his units. If things aren't going to match, see if the equipment vendor offers any options on the connections so they can match the local supply situation. If not, order adapters.

From actual project experience, please stay with one system. The NPT, IP system is available in the area of your project. I would not mix the two BSP vs NPT parts. You are asking for trouble.
Use pipe and flanges of the same system.
Good luck,

I am working on a Toner Manf. Facility here in the US and most of the equipment is coming from Europe. Making all the necessary connections is a nightmare.
To add to the difficulty the Process Engineer is Swiss, so we don't really communicate too well.

It has been suggested that I ask for blank flanges with major plant items. That way I can drill and match any flange to it and make the necessary connections.
Thats the theory any way

That might not be a bad way to do it, just make sure the flanges they install meet the Pressure rating you are trying to design to.
Also, if you are responsible for the drawings, be sure to add lots of notes for the Contractor to field verify the pipe spool lengths etc.
My recent problem was that a valve had a backing flange instead of a weld neck. This made the spool length wrong and the pipe fitter tried to blame the engineer (me). Except my drawing showed a backing flange, as did the equipment drawing. The Swiss didn't assemble it exactly per their Equipment drawing.
Not that it was a big deal, but I hate always being the one that takes the blame.
