1. What is Depth of Torispherical Head?

The Depth of Torispherical Head refers to the height of a formed head used in pressure vessels and storage tanks. This type of head combines a spherical crown with a toroidal knuckle section, providing optimal strength and pressure distribution characteristics for industrial applications.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ h_o = R_{co} - \sqrt{(R_{co} - \frac{D_o}{2}) \times (R_{co} + \frac{D_o}{2} - 2 \times R_{ko})} \]

Where:

\( h_o \) — Height of Formed Head (m)
\( R_{co} \) — Outer Crown Radius of Head (m)
\( D_o \) — Outer Shell Diameter (m)
\( R_{ko} \) — Outer Knuckle Radius of Head (m)

Explanation: This formula calculates the depth of a torispherical head based on the geometric relationships between the crown radius, shell diameter, and knuckle radius.

3. Importance of Head Depth Calculation

Details: Accurate calculation of head depth is crucial for pressure vessel design, manufacturing specifications, and ensuring proper fit and structural integrity in industrial equipment.

4. Using the Calculator

Tips: Enter all dimensions in meters. Ensure all values are positive and follow standard engineering conventions for pressure vessel head design.

5. Frequently Asked Questions (FAQ)

Q1: What is a torispherical head used for?
A: Torispherical heads are commonly used in pressure vessels, storage tanks, and reactors in chemical, petrochemical, and pharmaceutical industries due to their excellent pressure distribution characteristics.

Q2: How does crown radius affect head depth?
A: Larger crown radii generally result in shallower heads, while smaller crown radii produce deeper heads for the same shell diameter.

Q3: What are typical knuckle radius values?
A: Knuckle radius is typically 6-10% of the crown radius, with common values ranging from 0.06 to 0.1 times the crown radius in standard designs.

Q4: Are there industry standards for head dimensions?
A: Yes, standards such as ASME Section VIII Division 1 provide guidelines for torispherical head dimensions and design requirements.

Q5: Can this calculator be used for elliptical heads?
A: No, this calculator is specifically for torispherical heads. Elliptical heads have different geometric relationships and require separate calculations.
