How to calculate pipe grade
Did you know?
WebOften on plans, a grade is displayed as a ratio, such as 1 in 60. Sometime you may need to convert between Ratios, Percentage and even degrees. This page has a handy grade conversion calculator. Simply enter in either the ratio, percentage or degree value in the appropriate input and hit “convert” and the results are displayed below it. Web9 dec. 2024 · Solution: Pc = 80,000 [ (3.07/17.6605) – 0.0667] – 1955 = 6616 psi SF = 6616 / 3125 = 2.12. Allowable Collapse Pressure = 6616 psi / 1.125 = 5880 psi. Therefore from the previous casing collapse pressure calculations, the collapse load at 6000’ ( 3125 psi) is less than the allowable collapse ( 5880 psi), then it is safe to run.
WebThe program requires pipe grade to be entered in the form of 1 unit vertical to x units horizontal, written as 1 in x, or 1:x. For instance if the grade was 1 in 100, or 1:100, enter 100 in the box. Entering 1 in the box will give a grade of 1 in 1, that is 45 degrees. A slope of 1:200 is flatter than a slope of 1:100.
