cunifer

[GAZ700]

I have been looking for companies that are involved with welding cunifer,duplex and superduplex pipe,but my searches only seem to bring me back to the uk websites. i was wondering if they were trade names specific to the uk and if anybody knows what they are called over here.

Cunifer = CuproNickel?
Duplex and SuperDuplex are High Alloy and Higher Alloy stainless steels. and don't seem to be Elfland specific

You won't see a lot of superduplex. But you will see duplex just not a lot , the only duplex I've done was for dow chemical and albian sands in fort mac. We're kinda set in our way's when it comes to the super alloys. Jef

Here, you can hear it called Cupro-nickel or copper-nickel...but I've never heard it called cunifer.

i worked with kuni 20 years ago, i think it was used for low pressure application
(toilet waste pipework for the production platforms we built at rgc in methil, fife) im sure it was banned on mainland europe and the u.s. at that time. we were told to wear disposable overalls.... i never did....

im sure that copper had a high arsenic content years ago, its something to do with the smelting process.
