LINE TIGHTNESS
TEST METHOD
|
Certification
|
Leak
rate of 0.1 gph with PD = 99.99% and PFA = 0.37%.
|
|
Leak
Threshold
|
0.05
gph.
A pipeline system should not be declared tight if the
test result indicates a loss that equals or exceeds this
threshold.
Vendor claims this equipment can detect leaks at .01 gph,
and trains operators to declare leaks at .01 gph.
|
|
Applicability
|
Gasoline,
diesel, aviation fuel, fuel oil #4.
|
|
Specification
|
System
tests flexible pipelines.
Pretests are conducted at 90 psi.
Tests are conducted at 60 psi.
Mechanical line leak detector must be removed from pipeline
for duration of test.

|
Test
Period
|
Minimum
of 1 hour pretest consisting of 2 segments (30 minute
pressurization at 90 psi followed by 30 minute pressurization
at 60 psi).Minimum of 30 minute (two 15 minute readings)
test when the detected leak does not exceed 0.005 gph,
or minimum of 1 hour (four 15 minute readings) test when
the detected leak is more than 0.005 gph for the first
30 minutes. Test data are acquired and recorded manually.
