Unit Weight of MS Square Pipe as per IS Code

Weight Formula:

\[ W = \rho \times (a^2 - b^2) \]

Weight per Unit Length (W): kg/m

1. What is Unit Weight of MS Square Pipe?

Definition: This calculator computes the weight per meter of mild steel (MS) square pipes based on their dimensions and material density as per IS standards.

Purpose: It helps engineers, fabricators, and construction professionals estimate the weight of square pipes for structural calculations and material planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \rho \times (a^2 - b^2) \]

Where:

\( W \) — Weight per unit length (kg/m)
\( \rho \) — Density of mild steel (kg/m³, typically 7850)
\( a \) — Outer side length (meters)
\( b \) — Inner side length (meters)

Explanation: The formula calculates the cross-sectional area (outer area minus inner area) and multiplies by density to get weight per meter.

3. Importance of Weight Calculation

Details: Accurate weight estimation is crucial for structural design, transportation planning, cost estimation, and load calculations in construction projects.

4. Using the Calculator

Tips:

Enter density (default 7850 kg/m³ for mild steel)
Measure outer and inner dimensions in meters
For solid square bars, set inner dimension (b) to 0

5. Frequently Asked Questions (FAQ)

Q1: What is the standard density for MS pipes?
A: Mild steel typically has a density of 7850 kg/m³ as per IS standards.

Q2: How do I measure the side lengths accurately?
A: Use calipers for precise measurement. Convert mm to m (divide by 1000) before entering values.

Q3: What if my pipe is rectangular rather than square?
A: Use the formula W = ρ × t × (2(a + b) - 4t) where t is thickness, a and b are outer dimensions.

Q4: Does this account for manufacturing tolerances?
A: No, consider adding 2-5% to the calculated weight for practical applications.

Q5: How do I calculate total weight for a pipe length?
A: Multiply the result (kg/m) by the total length of the pipe in meters.
