Six free tools for the numbers you actually need before you specify or quote a tube sheet — tube count, weight, hole layout, pitch validation, unit conversion, and material comparison. No sign-up required.
Weight from diameter, thickness, and material density.
TRY IT BELOW ↓Maximum tubes for a given sheet diameter, tube OD, and pitch.
OPEN TOOL →Visualise triangular or square pitch patterns before drilling.
OPEN TOOL →Validate minimum pitch against TEMA requirements for your tube OD.
OPEN TOOL →Metric ⇄ imperial for thickness, diameter, and pressure.
OPEN TOOL →Side-by-side mechanical and corrosion properties, any two grades.
OPEN TOOL →Enter diameter, thickness, and material — get an estimated weight instantly. Useful for freight quoting and crane/lifting planning.
The weight calculator above estimates solid-plate weight; actual finished weight is typically 15–25% lower once the tube hole pattern is machined out, depending on tube density and pitch. For a precise figure on a real order, our engineering team calculates it directly from your finalised drawing.
No. They're planning and estimation tools for early-stage specification and budgeting. Final thickness, tube count, and pitch must be verified against the project's governing code (TEMA/ASME) by a qualified engineer before fabrication.
Yes — each tool includes an option to send your inputs and results directly to our engineering team as part of a quote request, saving you from re-entering the same specification twice.
Send your calculator results along with fluid service and destination — NPRO India will confirm the full specification and price.
