Frequently asked questions

What are SS 347H buttweld fittings?

SS 347H buttweld fittings are ASME B16.9 (and related) butt-weld pipe fittings used to change direction, branch, reduce, or close a line with a full-penetration weld.

Which standards apply?

Dimensional: ASME B16.9 / B16.28. Material: ASTM/ASME grade specs (e.g. A403, A234, A420, A860, A815, B366). Confirm edition and WP/WPHY class on the PO.

Seamless or welded fittings?

Both are supplied. Seamless is common for smaller sizes; welded (fabricated) covers larger OD. Match the construction to your piping class.

What should be on the purchase order?

Grade/UNS, fitting type and degree/radius, size/schedule or wall, seamless or welded, standard (B16.9), quantity, MTC (EN 10204 3.1/3.2), and any NACE/PMI/NDT extras.
