What piping calculators does Kalp Alloys publish?
Kalp Alloys publishes seven free engineering references: flange, pipe, round bar and sheet or plate weight calculators, plus a pipe schedule chart, an ASME B16.5 flange dimension chart, a stud bolt torque chart and a flange pressure-temperature rating chart. All are ungated.
Key Takeaways
- Every tool is ungated — no sign-up, no email address, no download form.
- The weight calculators cover carbon steel, stainless, duplex, nickel alloys, copper, titanium and aluminium.
- The pipe schedule chart gives outside diameter and wall thickness from NPS 1/2 inch to 24 inch, SCH 10 to XXS.
- The flange dimension chart gives outside diameter, thickness, bolt circle and bolt count for Class 150 and 300.
- The bolt torque chart covers ASTM A193 B7 studs together with the correct tightening sequence.
- The pressure-temperature chart shows how flange ratings fall as temperature rises, for carbon and stainless.
Weight calculators
Calculate weight for freight, costing and BOQ
Each calculator works from dimensions and material density, so any grade and size combination returns a figure rather than being limited to a lookup table.
Reference charts
Dimensional and rating references
Published in full on the page rather than behind a download form, so they can be checked, printed or quoted without an exchange of details.
Why these are published ungated
A reference chart behind a form is a lead capture device, not a reference. Engineers who need a wall thickness at eleven at night do not fill in forms; they find the next result. Publishing the data in full is what makes the page worth linking to, and links are what the page is for.
If a calculation raises a question the tools cannot answer, send the drawing or the line list to info@kalpalloys.com or on WhatsApp at +91 81608 73937. The technical team answers rather than a sales desk.
Frequently Asked Questions
Yes. All tools are free and ungated, with no sign-up or email address required, and can be used for as many line items as needed.
They are geometrically exact for the dimensions entered, but real material carries mill tolerance on wall thickness and diameter, so a weighed figure typically differs by a few per cent, and by up to about five per cent on thin-wall pipe.
They are reference values for estimating and checking. For design, always confirm against the current edition of the governing standard, because published tables are revised.
