    CLASS 2000 VS 3000 ASME B16.11

    According to ASME 16.11, plugs and bushings are not identified by class designation. They may be used for ratings up to Class 6000 designation. They are compatible with class 2000, 3000, and 6000 fittings.

    BigInch, thanks for your help. I was able to find a copy of 516 specifications on IHS. You are correct, the yield stregth is lower then expected. Thanks again!

    Gas Main 16" Weld Cap (Y52) - ASTM A516?

    Thanks, that was very helpful. You said, "516 Gr 70 has a tensile strength of 70ksi, but has a yield strength of 38ksi". Is the yield strength information provided in 516 specification?

    Gas Main 16" Weld Cap (Y52) - ASTM A516?

    I have a spec. calling for 16" welded cap (grade Y52) to be installed on the end of a gas main. Most cases the MSS-SP-75 and ASTM A234 is called for but in this case there is an additional requirement of ASTM A516 added. Whats the added benefit of using A516 besides improved notch toughness?
