Need more information here as "class 4000" doesn't exist.

Class 2000, 3000 & 6000 in B16.11,

There is some mention of NR 4000 which is something to do with Nuclear?. But doesn't otherwise exist AFAIK.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Who said it was class 4000?

Need a data sheet or vendor info.

Do you mean ANSI piping class 400?
