Clearance and overall dimension
This calculator determines the maximum overall equipment dimension (Da) and casing clearance using theory formulas from the product specification. Casing inner reference can be casing ID or drift.
Radial vs diametrical clearance
Radial clearance = (Dinner − Da) / 2. Diametrical clearance = Dinner − Da.
- Select unit and casing reference (ID or drift).
- Select equipment and cable sizes from reference tables.
- Compute offset height H and overall dimension Da for each controlling section.
- Take max(Da) and compare to casing inner diameter.
