Welcome to Islamabad's #1 bend pipe calculator, trusted by 78,000+ fabricators, HVAC contractors, and plumbers. Whether you're bending pipes for I-8 commercial buildings, F-10 residential projects, or industrial plants in I-9, get exact cut lengths, bend allowances, and setbacks instantly.

How the Bend Pipe Calculator Works

Our bend pipe calculator uses ASME B31.3 and ASTM standards with neutral axis compensation for accurate bending.

• Bend Allowance: π × R × (Angle/180) × K-factor
• Setback: R × (1 - cos(Angle))
• Cut Length: Leg1 + Leg2 + Allowance - Setback

Bend Pipe Calculator: Standard Radii

• 1D: R = 1 × OD (tight bends)
• 1.5D: R = 1.5 × OD (standard)
• 3D–5D: R = 3–5 × OD (long radius)
• Custom: Up to 20D for large pipes
