ASME B16.9 wrought Tee with weld within it

ASME B16.9 wrought Tee with weld within it

ASME B16.9 wrought Tee with weld within it

Section 1.3 of ASME B16.9 specifies the following:

“Fabricated laterals and other fittings employing circumferential or intersection welds are considered pipe fabrication and are not within the scope of this Standard.”

If two halves of a large tee are forged then welded together with 100% radiography of the weld is there a way of allowing the Tee to remain compliant with ASME B16.9?

RE: ASME B16.9 wrought Tee with weld within it

I believe so, as it aint a lateral or other fitting not listed in B16.9. It's a tee. Stainless steel tee's (and other fittings to B16.9) are often made using welds, e.g. acc A403 WP316-316L-WX, where the -WX identifies a weld with a certain amount of NDE on the material.

RE: ASME B16.9 wrought Tee with weld within it

Tee welded in two halves does not comply to 1.3 of ASME B16.9.
