    15050. 2. The allowable leakage rate for other systems shall be zero at the specified test pressure

    throughout the specified duration.

    D. Nitrogen or Air Pressure Testing: 1. Nitrogen gas or oil-free dry air may be used to test steel lines. Testing consists of gradually

    introducing nitrogen gas or dry air up to 50 PSI and maintaining this pressure while testing the line for leaks with soapy water. When the system is free from leaks at this pressure, the test pressure shall then be increased in increments of 50 PSI up to a maximum of 150 PSI. At each stepped increase in pressure, check for leaks and take corrective action as necessary. When the system is free from leaks at the final test pressure, the system shall then be depressurized, the test source disconnected, and the system capped to prevent the entrance of water.

    2. For testing with nitrogen gas, use cylinders of dry high purity nitrogen gas, nitrogen-handling cylinder mounted pressure regulator 0 to 300 PSI, and necessary fittings and adapters to complete connection between the source and system header. Pressure regulator shall be self-relieving type which vents to the atmosphere and include a throttling valve.

    3. For testing with air, provide oil-free air with a relative humidity of zero. Fittings, adapters, and accessories, pressure regulator and throttling valve shall be suitable for pressure testing with air and rated for 300 PSI service.

    4. Nitrogen gas shall be used to test all GOX piping.

    E. Hydraulic, Lube, and Fuel Oil Systems: 1. For fluid power systems, the manufacturer shall supervise the installation and testing of system

    components including field piping.

    F. Refrigerant Systems: Test pressure shall be applied in two stages before any refrigerant pipe is insulated or covered. First stage test shall be at 10 psi with every joint being tested with a thick soap or color indicating solution. Second stage tests shall raise the system to the minimum refrigerant leakage test pressure specified in ANSI/ASHRAE 15 & 34 with a maximum test pressure 25 percent greater.

    G. Drains: Drain systems, other than pumped drain systems, shall be tested in accordance with UPC.

    3.05 HYDROSTATIC TESTING OF PIPELINES AND APPURTENANCES

    A. Water for testing pipelines shall be furnished by the Contractor. Be responsible to convey the water from the source to the points of use.

    D. Disposal of flushing water and water containing chlorine shall be in accordance with Section 02271.

    E. Determine and select test equipment, temporary valves, bulkheads, and other water control equipment.

    F. Pipeline 24-inches diameter and larger shall be video inspected in accordance with Section 02761 prior to hydrostatic testing.

    G. Prior to hydrostatic testing, pipelines shall be flushed.

    H. Test pipelines in sections not to exceed one mile in length.

    I. Test shall be made by closing valves when available or by placing bulkheads and filling the line slowly with water.

    J. Be responsible for ascertaining that test bulkheads, valves, concrete thrust blocking or other means of restraint are suitable to resist the thrust of the test pressure without damage to or movement of the adjacent pipe.

    K. Unharnessed sleeve-type couplings, expansion joints, or other sliding joints shall be restrained or suitably anchored prior to the test to avoid movement and damage to piping and equipment.

    L. Remove or protect pipeline-mounted devices that may be damaged by the test pressure.

    M. Provide sufficient means to allow trapped air to exit. Air relief valves shall be open during pipeline filling.

    N. Pipeline shall be filled at a rate which will not cause surges or exceed the rate at which the air can be released through the release valves.

    O. Air within the pipeline shall be allowed to escape completely.

    P. Differential pressure across the orifices in the air release valves shall not be allowed to exceed five psi at any time during filling.

    Q. After the pipeline has been filled, it shall be allowed to stand under a slight pressure for at least 24 hours to allow the concrete or mortar lining to absorb water and to allow the escape of air from air pockets.

    R. During this period, bulkheads, valves, and connections shall be examined for leaks.

    S. If leaks are found, corrective measures satisfactory to the Project Representative shall be taken.

    T. Hydrostatic test shall consist of holding the indicated test pressure on the pipeline segment for a period of four hours.

    U. Test pressure for piping shall be as specified in the PIPESPEC for the type and size of piping being tested.

    V. Test pressure shall be achieved for all elevations along the pipeline.

    W. No pressure test will be required for a reservoir overflow line.

    X. Leaks that appear during testing shall be repaired in a manner acceptable to the Project Representative. If a leak in buried pipeline is detected, it shall be excavated, located, repaired and retested until pipeline passes the pressure test requirements.

    Y. Add water to restore the test pressure if the pressure decreases five psi below test pressure during the test period.

    Z. Connection to the existing wastewater system shall be made following successful completion of hydrostatic testing.

    3.06 CLEANING AND FLUSHING

    A. General: Piping systems shall be cleaned following completion of testing and prior to connection to operating, control, regulating, or instrumentation equipment. The Contractor may, at its option, clean and test sections of buried or exposed piping systems. Use of this procedure, however, will not waive the requirement for a full pressure test of the completed system. Unless specified otherwise, piping 24 inches in diameter and smaller shall first be cleaned by pulling a tightly fitting cleaning ball or swab through the system. Piping larger than 24 inches in diameter may be cleaned manually or with a cleaning ball or swab. Upon completion of the cleaning, connect the piping systems to related equipment and structures.

    B. Temporary Screens: 1. Upon completion of the cleaning, connect the piping systems to related process equipment and

    structures. Temporary screens, provided with locator tabs which remain visible from the outside when the screens are in place, shall be inserted in pipelines at the suction of pumps and compressors in accordance with the following table:

    2. Maintain the screens during testing, initial start-up, and initial operating phases of the commissioning process. In special cases, screens may be removed as required for performance tests. Remove the temporary screens and make the final piping connections after the screens have remained clean for at least 24 consecutive hours of operation. Systems handling solids are exempt.

    C. Gas and Air Systems: Unless otherwise specified, gas and air system piping 6 inches in diameter and smaller shall be blown out, using air or the testing medium specified. Piping larger than 6 inches shall be cleaned by having a swab or "pig" drawn through the separate reaches of pipe. After connection to the equipment or structure, it shall then be blown out using the equipment. Upon completion of cleaning, the piping shall be drained and dried with an air stream. Natural gas and propane systems shall be purged with nitrogen and a nitrogen pad maintained at 10 PSI until put in service.

    D. Liquid Systems: After completion of cleaning, liquid systems, unless otherwise specified, shall be flushed with clean water. With temporary screens in place, the liquid shall be circulated through the piping system using connected equipment for a minimum period of 15 minutes and until no debris is collected on the screens.

    E. Potable Water Systems: Potable water piping systems shall be flushed and disinfected in accordance with AWWA C600 and C651.
