DO YOU KNOW HOW TO CALCULATE HYDROTEST PRESSURE? HOW TO CALCULATE VOLUME OF HYDROTEST WATER?

HYDROTEST PRESSURE TEST CALCULATION:
SIMPLE EXAMPLE HYDROTEST PRESSURE CALCULATION
Initial test pressure
Calculation for Pipe: for 30” X 0.893” WT, API 5L Gr X70 pipe
Considering 90% of SMYS,
P= (2X 0.893” X 70000 X 0.9) / 30= 3750 psig
Considering 96% of SMYS,
P= (2X 0.893” X 70000 X 0.96) / 30= 4000 psig
Flange limitation: 1500# RTJ ANSI Flange: = 5575 psig
Flange limitation: 1500# RTJ ANSI Valves:
Body test= 5575 psig
Seat test= 4075 psig
So the Hydrotest Pressure for the test headers will be 4000psig
(considering 96% SMYS- limited by Pipewall Thickness)
What is the Barlow formula for pipe thickness?
Barlow's Formula is a calculation used to show the relationship between internal pressure, allowable stress (also known as hoop stress), nominal thickness, and diameter. It is helpful in determining the maximum pressure capacity a pipe can safely withstand. The formula is expressed as P=2St/D, where: P= Hydrotest pressure
What is Barlow's equation used for?
Barlow's formula (called "Kesselformel" in German) relates the internal pressure that a pipe can withstand to its dimensions and the strength of its material. This approximate formula is named after Peter Barlow, an English mathematician.
Is hydrotest pressure 1.3 or 1.5 times?
The hydrostatic test pressure at any point in the piping system shall not be less than 1.5 times the design pressure, but shall not exceed the maximum allowable test pressure of any non-isolated component, nor shall it exceed the limits of calculated stresses due to occasional loads.
