Do the math before you send the RFQ.

The same calculators our own engineers use — pipe schedules, weights and grade selection, free and ungated.

Tool 01 — Pipe schedule calculator

NPS + schedule → dimensions & weight

Pick a nominal size and schedule; get OD, wall, ID, cross-section and weight per metre for your grade (ANSI B36.10 / B36.19).

Tool 02 — Grade comparison

Two grades, side by side — with a verdict.

Compare chemistry, strength, temperature and corrosion resistance. The verdict line tells you which alloy wins for which service.

PropertyGrade AGrade B

Nominal published values, annealed condition. Certified heats ship with actual MTC values. PREN = Cr + 3.3×Mo + 16×N (qualitative for Ni alloys).
