Thickness of Gland Flange Calculator

Thickness of Gland Flange Formula:

\[ h = \frac{d_{shaft}}{8} + 12.5 \]

Thickness of Gland Flange (mm):

Minimum Thickness (mm):

Maximum Thickness (mm):

1. What is Thickness of Gland Flange?

Definition: Thickness of Gland Flange is a protruded ridge, lip or rim, either external or internal for stabilizing and guiding the movements of a machine or its parts. Gland flanges are used in ball valve stuff box.

Purpose: This calculator helps determine the proper thickness of gland flange based on shaft diameter with tolerance considerations.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{d_{shaft}}{8} + 12.5 \]

Where:

\( h \) — Thickness of gland flange (mm)
\( d_{shaft} \) — Diameter of shaft (mm)

Explanation: The thickness is calculated as one-eighth of the shaft diameter plus 12.5 mm, with an optional tolerance percentage.

3. Importance of Gland Flange Thickness

Details: Proper gland flange thickness ensures stability, proper sealing, and longevity of mechanical components in various applications.

4. Using the Calculator

Tips: Enter the shaft diameter in millimeters and tolerance percentage (default ±5%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard tolerance for gland flange thickness?
A: Typically ±5%, but this may vary based on specific application requirements.

Q2: Can I use this calculator for different materials?
A: The formula is generally applicable, but material properties may require additional considerations.

Q3: What if my shaft diameter is very large?
A: The formula scales linearly with shaft diameter, but verify with engineering standards for large diameters.

Q4: Why is 12.5 mm added in the formula?
A: This is a standard base thickness that ensures minimum structural integrity regardless of shaft size.

Q5: How precise should the thickness measurement be?
A: Typically measured to within ±0.1 mm for critical applications.
