Frequently asked questions — ASTM A269 TP347H Seamless Tube

What is ASTM A269 TP347H?

A269 covers seamless and welded austenitic stainless tube for general corrosion-resisting and low/high-temperature service. This page focuses on TP347H / 347H.

A269 vs A213?

Use A213 when the datasheet requires boiler/HX tube rules; A269 for general service / instrumentation packages.

Seamless or welded tube?

Both exist under A269. This page is the seamless tube route — confirm welded if the PO allows.
