3.5PIPE JOINT CONSTRUCTION

  1. Refer to Division22 Section "Common Work Results for Plumbing" for threaded joint construction requirements for soldered and brazed joints in copper tubing; threaded, welded, and flanged joints in steel piping.

3.6FIELD QUALITY CONTROL

  1. Prepare process fluids piping according to ASMEB31.9 and as follows:
  2. Leave joints, including welds, uninsulated and exposed for examination during test.
  3. Provide temporary restraints for expansion joints that cannot sustain reactions due to test pressure. If temporary restraints are impractical, isolate expansion joints from testing.
  4. For Water Soluble systems, flush system with clean water. Clean strainers.
  5. Isolate equipment from piping. If a valve is used to isolate equipment, its closure shall be capable of sealing against test pressure without damage to valve. Install blinds in flanged joints to isolate equipment.
  6. Install safety valve, set at a pressure no more than one-third higher than test pressure, to protect against damage by expanding liquid or other source of overpressure during test.
  7. Perform the following tests on process fluids piping:
  8. Use ambient temperature water, for water soluble coolant systems, as a testing medium unless there is risk of damage due to freezing. Another liquid that is safe for workers and compatible with piping may be used.
  9. While filling system, use vents installed at high points of system to release trapped air. Use drains installed at low points for complete draining of liquid.
  10. Subject piping system to hydrostatic test pressure that is not less than 1.5 times the design pressure. Test pressure shall not exceed maximum pressure for any vessel, pump, valve, or other component in system under test. Verify that stress due to pressure at bottom of vertical runs does not exceed either 90 percent of specified minimum yield strength or 1.7 times "SE" value in AppendixA of ASMEB31.9, "Building Services Piping."
  11. After hydrostatic test pressure has been applied for at least 10 minutes, examine piping, joints, and connections for leakage. Eliminate leaks by tightening, repairing, or replacing components, and repeat hydrostatic test until there are no leaks.

3.7CLEANING

  1. Flush machine water soluble coolant piping systems with clean water. Remove and clean or replace strainer screens. After cleaning and flushing process fluids piping systems, but before balancing, remove disposable fine-mesh strainers in pump suction diffusers.
