1/4-18 npt taper angle

1/4-18 npt taper angle- The angle between the taper and the center axis of the pipe is tan −1 (1 ⁄ 32) ≈ 173° ≈ 1° 47′ The standard for Nominal Pipe Size (often abbreviated NPS, which should not be confused with the symbol NPS for the straight thread form standard) is loosely related to the inside diameter of Schedule 40 series of sizesThe basic dimensions of the ANSI Standard Taper Pipe Thread are given in inches to four or five decimal places While this implies a greater degree of precision than is ordinarily attained, these dimensions are the basis of gage dimensions and are so expressed for the purpose of eliminating errors in computations
