P265TR1 is a pressure-tube material designation with room-temperature properties and TR1 quality requirements.
The P265 base and TR1 suffix both matter when identifying an ordered material.
Confirm P265TR1 against the intended welding or seamless route, correct product standard and service conditions.
P265TR1 is not a blanket substitute for P235TR1 or P265TR2.
Related catalogue context is not a certification statement. Validate process, edition, product scope and the supplier's actual offer.
These are references from the governed public source record, not a statement of equivalence or current certification.
