1. What is Pipe Burst Pressure Calculation?

Definition: This calculator estimates the internal pressure that would cause a pipe to burst based on material properties and pipe dimensions.

Purpose: It helps engineers and technicians determine the maximum safe operating pressure for pipes in various applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Burst pressure (psi)
• \( S \) — Material stress (psi)
• \( t \) — Wall thickness (inches)
• \( D \) — Pipe diameter (inches)

Explanation: The formula calculates the hoop stress in a thin-walled cylindrical pressure vessel, which determines the burst pressure.

3. Importance of Burst Pressure Calculation

Details: Proper pressure estimation ensures pipeline safety, prevents catastrophic failures, and helps in material selection for specific pressure requirements.

4. Using the Calculator

Tips: Enter the material stress (yield strength), wall thickness, and pipe diameter. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What material stress value should I use?
A: Use the yield strength of the pipe material, which can be found in material specifications (e.g., 35,000 psi for mild steel).

Q2: Does this work for all pipe sizes?
A: This formula is most accurate for thin-walled pipes (where D/t > 20). For thick-walled pipes, more complex formulas are needed.

Q3: Should I include a safety factor?
A: Yes, typical safety factors range from 2 to 4 depending on application. Divide the result by your safety factor for working pressure.

Q4: How does temperature affect the calculation?
A: Material strength decreases at higher temperatures. Use temperature-adjusted material properties for high-temperature applications.

Q5: What about pipe joints or connections?
A: Joints are often the weakest point. Consider separate calculations or testing for connection points.
