1. What is the Thickness of Pressurized Cylinder Calculation?

The thickness of pressurized cylinder wall calculation determines the minimum wall thickness required for a cylindrical pressure vessel to safely contain internal pressure without failure. This is a critical engineering calculation for pressure vessel design and safety.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ t_w = \frac{d_i}{2} \times \left( \sqrt{\frac{\sigma_t + P_i}{\sigma_t - P_i}} - 1 \right) \]

Where:

\( t_w \) — Thickness of pressurized cylinder wall (m)
\( d_i \) — Inner diameter of pressurized cylinder (m)
\( \sigma_t \) — Permissible tensile stress in pressurized cylinder (Pa)
\( P_i \) — Internal pressure on cylinder (Pa)

Explanation: The formula calculates the minimum wall thickness required to withstand internal pressure based on the cylinder's dimensions and material properties.

3. Importance of Cylinder Wall Thickness Calculation

Details: Accurate wall thickness calculation is crucial for pressure vessel safety, preventing catastrophic failures, ensuring structural integrity, and complying with engineering standards and regulations.

4. Using the Calculator

Tips: Enter inner diameter in meters, permissible tensile stress in Pascals, and internal pressure in Pascals. All values must be positive, and permissible tensile stress must be greater than internal pressure.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of permissible tensile stress?
A: Permissible tensile stress represents the maximum stress the material can withstand safely, typically derived from material properties with appropriate safety factors.

Q2: Can this formula be used for all pressure vessels?
A: This formula is specifically for thick-walled cylinders under internal pressure. Different formulas apply for thin-walled vessels or external pressure scenarios.

Q3: What safety factors should be considered?
A: Engineering standards typically require additional safety factors beyond the calculated minimum thickness to account for material defects, corrosion, and unexpected load conditions.

Q4: How does temperature affect the calculation?
A: Elevated temperatures can reduce material strength, so high-temperature applications may require using reduced permissible stress values.

Q5: Are there standards that govern these calculations?
A: Yes, various international standards (ASME, EN, etc.) provide detailed guidelines for pressure vessel design and thickness calculations.
