A.
PIPE TESTING
CONTRACTOR shall perform a pneumatic test on solid pipe and fittings greater
than 50 ft in length after placement in the trench, in accordance with the
Manufacturer’s recommendations.
Pipes shall be pressure tested in presence of ENGINEER. Provide a minimum 7
days notice to ENGINEER before performing test.
Pneumatic testing shall be performed as follows:
1. The test period at the test pressure shall last no less than 10 minutes.
2. Provide all necessary connections, bulkheads, flanges, bracing, and
blocking, as well as all required test equipment.
3. Test pressure gauges:
a. For GCCS and condensate main pipes, the test pressure gauge shall
have a maximum range of no more than 20 psig, with minor
gradations no greater than 0.1 psig.
b. For the compressed air pipe, the test pressure gauge shall have a
maximum range of no more than 200 psig, with minor gradations no
greater than 1 psig.
4. Pipe to be tested shall be exposed in the trench, except bends, reduced
pressure rated fittings and components, which shall be buried or
restrained. Flange connections shall be visible to check for leaks.
5. Test pressure:
a. For GCCS and condensate main pipes, the test pressure shall be 10
psig.
b. For the compressed air pipe, the test pressure shall be 75 psig.
6. Test shall be accepted if the pressure drop over 10 minutes is less than 5
percent of the pressure at the beginning of the test period.
Test Report
1. ENGINEER shall prepare and submit to OWNER a test report using the
attached forms for each pipe system tested. Include following information
in test report.
Date of test.
Description and identification of pipe system tested.
Type of test performed.
Test fluid.
Test pressure.
