1. What is Hoop Tension in Pipe Shell?

Hoop Tension in Pipe Shell in KN/Square Meter is the stress that occurs along the pipe's circumference when pressure is applied in KN/Square Meter. It represents the tensile force per unit area that acts circumferentially in the pipe wall.

2. How Does the Calculator Work?

The calculator uses the Hoop Tension formula:

\[ f_{KN} = \frac{P_{wt} \times R_{pipe}}{h_{curb}} \]

Where:

\( f_{KN} \) — Hoop Tension in Pipe Shell (KN/m²)
\( P_{wt} \) — Water Pressure in KN per Square Meter
\( R_{pipe} \) — Pipe Radius (m)
\( h_{curb} \) — Curb Height (m)

Explanation: The formula calculates the circumferential stress in a pipe subjected to internal water pressure, considering the pipe radius and curb height constraints.

3. Importance of Hoop Tension Calculation

Details: Accurate hoop tension calculation is crucial for pipe design and structural integrity assessment. It helps determine if the pipe material can withstand the internal pressure without failure or excessive deformation.

4. Using the Calculator

Tips: Enter water pressure in KN/m², pipe radius in meters, and curb height in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the physical significance of hoop tension?
A: Hoop tension represents the tensile stress that develops in the circumferential direction of a pipe when subjected to internal pressure, which is critical for determining pipe wall thickness requirements.

Q2: How does pipe radius affect hoop tension?
A: Larger pipe radii result in higher hoop tension for the same internal pressure, as the tension is directly proportional to the radius.

Q3: What is the role of curb height in this calculation?
A: Curb height acts as a constraint factor that influences the distribution and magnitude of hoop tension in the pipe shell.

Q4: What units should be used for accurate results?
A: Consistent SI units should be used - pressure in KN/m², dimensions in meters, resulting in hoop tension in KN/m².

Q5: Can this formula be used for all pipe materials?
A: The formula is fundamental for thin-walled pressure vessels, but material-specific safety factors and additional considerations may be needed for different materials.
