Technical Resources – Charts, Calculators & Guides
These technical resources bring together the piping technical charts, calculators and guides that engineers, buyers and fabricators use every day when specifying pipes, fittings, flanges, plates and bars. Each chart is based on the relevant ASME or ASTM standard, and each guide explains the practical differences that matter when choosing a material or product.
Charts and calculators
- Pipe schedule chart – outside diameter, wall thickness and weight per metre for each nominal pipe size and schedule to ASME B36.10M and B36.19M.
- Weight calculator – theoretical weight of round and square bars, hexagons, sheets, plates, pipes and rings in many metals.
- Flange dimensions chart – ASME B16.5 flange dimensions and bolting by class.
- Butt-weld fitting dimensions – elbow, tee and reducer dimensions to ASME B16.9.
- Grade equivalent chart – ASTM, UNS, EN and other equivalent designations.
Comparison guides
- SS 304 vs 316 – composition, corrosion resistance and where each grade is used.
- Seamless vs welded pipe – how they are made, standards and when to choose each.
- A106 vs A53 vs API 5L – the three common carbon steel pipe standards compared.
The charts give nominal or theoretical values for guidance. For design and purchasing, always refer to the current edition of the standard and the project specification. If you need help with a size, grade or specification, contact us and our team will help.
Seamless vs Welded Pipe
Manufacture, pressure rating, cost and availability of seamless and welded pipe compared.

Frequently Asked Questions
Yes. Pipe dimensions are from ASME B36.10M and B36.19M, flange dimensions from ASME B16.5 and butt-weld fitting dimensions from ASME B16.9. The values are for guidance; always check the current edition of the standard for design.
It gives the theoretical weight for the nominal dimensions and the density of the selected material. Actual weights vary with the tolerances allowed by the product standard.
Yes. Send us the product, size, grade and specification, and our team will confirm the details and availability.
