CALCULATORS & REFERENCES

Five free tools our engineers use every day — check bend feasibility, estimate weight, and convert specifications before you request a quote.

Tube Weight Calculator

Theoretical weight of round tube by material, OD, wall thickness, and length — with batch quantity estimates.

Open tool

D/t Ratio Checker

Evaluate wall thickness ratio to determine bendability, mandrel requirements, and tooling complexity.

Open tool

Springback Reference

Material-specific overbend angles for precision bending, plus the full springback compensation table.

Open tool

Unit Converter

Inches ↔ millimeters, pounds ↔ kilograms, PSI ↔ bar — with gauge references for common tube dimensions.

Open tool

Minimum Bend Radius Lookup

Minimum center-line radius (CLR) by material and OD for quick mandrel selection and tooling verification.

Open tool

These tools provide engineering estimates for preliminary planning. Material hardness, tooling, and machine capabilities affect production results — contact Harco engineering for production-grade specifications.
