What to know before ordering to ASTM B163
The points that decide whether material to ASTM B163 is accepted at inspection.
- Tubes are ordered by OD and wall, with U-bending as an optional requirement.
- Non-destructive testing of every tube is standard.
- For process pipe in the same alloys, use the pipe specifications (B423, B165, B167).

How ASTM B163 fits into an order
A purchase order line is only complete when it names the material standard, the dimensional standard and the inspection document. Miss one and the mill, the inspector and the buyer can each read the order differently.

ASTM B163 — questions buyers ask
What does ASTM B163 cover?
Covers seamless nickel and nickel-alloy condenser and heat-exchanger tubes, including alloys 600, 800, 825 and Monel 400.
Which grades do you supply to ASTM B163?
Inconel 825, Inconel 600, Incoloy 800 / 800H / 800HT, Monel 400 — see the table on this page for the exact product and designation.
What is the difference between ASTM B163 and ASME SB-163?
ASME SB-163 is the ASME Boiler and Pressure Vessel Code (Section II) adoption of ASTM B163. The technical requirements are usually identical to a specific ASTM edition; pressure-equipment codes call for the ASME designation, and most mill certificates show both.
Do you supply certificates to this standard?
Yes. Material is supplied with mill test certificates to EN 10204 3.1 showing the standard, grade and heat number; 3.2 with third-party inspection on request.
