Pipe Support Calculator — Calculate Pipe Span, Load & Support Requirements

Pipe Support Calculator

Calculate pipe support span, load requirements, and support spacing. Determine proper pipe support specifications based on pipe size, material, and contents.

Step 1: Pipe Properties

4″

Understanding Pipe Support Requirements

Proper pipe support spacing depends on pipe diameter, material, contents, and operating temperature. Larger diameters and heavier materials require closer support spacing.

Step 2: Support Conditions

70°F

About Pipe Support Spacing

Proper support spacing prevents sagging, vibration, and stress concentration. Factors affecting spacing include pipe material, contents weight, temperature, and support type.

Support Spacing Formula

Maximum Span = √(Z × S / (0.75 × W))

Where: Z = Section Modulus, S = Allowable Stress, W = Total Weight per unit length. Based on ASME B31.1 and B31.3 standards.
