Certification |
Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100% and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA
= 0%.
*Since leak
rate varies as a function of pressure, this leak rate and pressure were
certified using an equivalent leak rate and pressure, in accordance with an
acceptable protocol.
|
|
Leak Threshold |
1.5 gph for leak
rate of 3.0 gph.
0.1 gph for leak rate of 0.2 gph.
0.079 gph for leak rate of 0.1 gph.
A pipeline system should not be declared tight if the test result indicates
a loss that equals or exceeds this threshold. |
|
Applicability |
Gasoline, diesel, aviation fuel, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467,
biodiesel B100 meeting ASTM D6751.
|
|
Specification |
System tests
pressurized flexible pipelines.
Tests are conducted at operating pressure.
System will not function with a mechanical line leak detector installed in
the pipeline. |
|
Pipeline Capacity |
Maximum of 49.6
gallons. |
|
Waiting Time |
None between
delivery and testing.
Minimum between dispensing and testing depends on volume of product and
temperature gradient which is determined by system's computer.
|
|
Test Period |
Response time is
1 minute for leak rate of 3.0 gph.
Response time is 45 minutes to 8 hours, 51 minutes for leak rate of 0.2 gph.
Response time is 1 hour, 12 minutes to 12 hours, 54 minutes for leak rate of
0.1 gph.
Test data are acquired and recorded by a microprocessor.
Calculations are automatically performed by the microprocessor.
|
|
System Features |
Permanent
installation on pipeline.
Automatic testing of pipeline.
Preset threshold.
If
pump side leak testing is required, total vertical rise of pipeline must not
exceed 8 feet above VLLD Controller.
Single test to determine if pipeline is leaking.
Pump shutdown, message display and alarm activation if leak is declared.
|
|
Calibration |
System must be
checked annually and, if necessary, calibrated in accordance with
manufacturer's instructions. |
