Where can I find minimum wall tickness for socket welding classe 300 size 3'' and 4''?

RE: sw wall thickness

(OP)
I have what I want in b16.34a-1998 table4, but only covers sizes up to 2 1/2'' and I need size 3'' and 4''

RE: sw wall thickness

ANSI B16.11 has dimensions for SWE 3" & 4" including minimum wall thicknesses.

RE: sw wall thickness

General industry practice is to limit socketweld piping to 2" NPS.  Piping 3" NPS and larger is usually buttwelded.  

RE: sw wall thickness

Murio,
The reply by dfteng is right. However, there is Class 3000 instead of 300.

RE: sw wall thickness

in our specifications we don't provide schedule, however we mention the dimensions as per ANSI B 16.11, but the pressure clas mentioned is 3000#. i will request you to check ur pressure class.
