Pipe Calculator: ASME & NPS

Pipe dimensions, flange charts, offsets and weight — all in one offline app built for piping engineers and pipefitters.

Pick an NPS and schedule and instantly get OD, wall thickness, ID and weight per meter for carbon steel (ASME B36.10M) and stainless steel (ASME B36.19M). No tables, no searching PDFs, no signal needed.

PIPE DIMENSIONS — ASME B36.10M & B36.19M
- Switch between carbon and stainless steel in one tap
- OD, wall thickness, ID and kg/m for every size
- NPS 1/8" to 24" (DN 6 to DN 600) with NPS ↔ DN conversion
- SCH, STD and XS wall classes plus stainless S schedules

PIPE OFFSET CALCULATOR
- 45°, 90° and odd-angle offsets
- Set and roll inputs for rolling offsets
- Long radius (LR) and short radius (SR) elbows
- Weld gap allowance at each end for accurate cut lengths

FLANGE RULER — ASME B16.5
- Standard flange dimensions by NPS and pressure class
- Flange OD, bolt hole count and bolt diameter
- Matched to the pipe size you select

WEIGHT & COST
- Total pipe weight for any length and schedule
- Enter cost per kg for instant material budgets
- Ideal for takeoffs, procurement and shipping
