Minimum Wall Calculator
Calculate minimum acceptable wall thickness using a −12.5% wall tolerance.
Wall Thickness Input
Formula: Minimum Wall = Nominal Wall × 0.875
Minimum Wall Result
Nominal Wall0.190"
12.5% Reduction0.024"
Minimum Wall0.166"
0.190 × 0.875 = 0.166 in minimum wall

Drift Calculator
Simple shop calculator: select Tubing or Casing, enter the ID, and get the drift diameter.
Enter Pipe Information
Tubing uses a 3/32" (0.09375") deduction. Casing uses a 1/8" (0.125") deduction in this simplified shop calculator.
Result
Pipe ID1.610"
Deduction0.09375"
Drift Diameter1.516"
1.610 − 0.09375 = 1.51625 → 1.516"
Quick Reference
Product
Deduct From ID
Example
Tubing
3/32" = 0.09375"
1.610 − 0.09375 = 1.516"
Casing
1/8" = 0.12500"
2.992 − 0.12500 = 2.867"
This simplified page is intended for the tubing/casing sizes you have been using. For other API size ranges, verify the required drift allowance before use.
Thread Height Calculator
Enter the maximum and minimum major/minor diameters to calculate the allowable thread-height range.
Enter Diameter Limits
Minimum Height = (Major MIN − Minor MAX) ÷ 2
Maximum Height = (Major MAX − Minor MIN) ÷ 2
Thread Height Limits
MIN Thread Height0.0575"
MAX Thread Height0.0675"
Total Height Range0.0100"
Acceptable radial thread height: 0.0575" to 0.0675"
Calculation Breakdown
MIN Thread Height
(2.3650 − 2.2500) ÷ 2 = 0.0575"
MAX Thread Height
(2.3750 − 2.2400) ÷ 2 = 0.0675"
Allowable Height Range
0.0575" – 0.0675"
These are calculated dimensional limits from the major/minor diameters you enter. They are not automatically API acceptance limits unless the entered diameter limits come from the applicable thread specification.
Taper Calculator
Enter any three values: Small End Diameter, Large End Diameter, Length, and Taper per Foot. The calculator determines the missing value.
Taper Dimensions
Enter exactly 3 fields. Formula: Taper/ft = (Large Diameter − Small Diameter) × 12 ÷ Length.
