SS Pipe Weight Chart in kg/mtr

SS Pipe Weight Formula:

\[ W = \rho \times \pi \times \frac{OD^2 - ID^2}{4} \]

Weight per Meter (W): kg/m

1. What is SS Pipe Weight Calculator?

Definition: This calculator estimates the weight per meter of stainless steel pipes based on their dimensions and material density.

Purpose: It helps engineers, fabricators, and construction professionals determine pipe weights for structural calculations and material planning.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ W = \rho \times \pi \times \frac{OD^2 - ID^2}{4} \]

Where:

\( W \) — Weight per meter (kg/m)
\( \rho \) — Density of stainless steel (kg/m³)
\( OD \) — Outer diameter of pipe (meters)
\( ID \) — Inner diameter of pipe (meters)

Explanation: The formula calculates the cross-sectional area of the pipe wall and multiplies by density to get weight per unit length.

3. Importance of Pipe Weight Calculation

Details: Accurate weight calculations are essential for structural integrity, transportation planning, and cost estimation in piping projects.

4. Using the Calculator

Tips: Enter the density (default 7930 kg/m³ for SS304), outer diameter, and inner diameter in meters. All values must be positive with OD > ID.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for stainless steel pipes?
A: Common densities are 7930 kg/m³ for SS304 and 8000 kg/m³ for SS316, but this varies by alloy composition.

Q2: How do I measure pipe diameters?
A: Measure OD directly with calipers. For ID, you can measure wall thickness and subtract twice from OD (ID = OD - 2×thickness).

Q3: What if my pipe is solid (no inner diameter)?
A: Set ID = 0 to calculate weight for a solid stainless steel rod.

Q4: Can I use this for other materials?
A: Yes, by changing the density value. For carbon steel use 7850 kg/m³, for aluminum use 2700 kg/m³.

Q5: How accurate is this calculation?
A: It provides theoretical weight. Actual weight may vary slightly due to manufacturing tolerances and surface finish.
