Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 16805-2009 "liquid petroleum pipeline pressure test", compared with GB/T 16805-2009, the main technology The changes are as follows.

--- Modify the "normative references" (see Chapter 2);

--- Added "Terms and definitions" (see Chapter 3, 2009 version Chapter 3);

--- Added "stress test type" (see Chapter 4);

--- Modify the "pressure test medium" (see Chapter 5, 2009 version Chapter 5);

--- Increase the "pressure test personnel qualifications" (see Chapter 8);

--- Added "stress test failure" content (see Chapter 10);

--- Added "Find Leaks" (see Chapter 10);

--- Added "pressure test medium pressure relief, replacement and disposal of" content (see Chapter 10);

--- Modify the "stress test record" (see Chapter 12, 2009 edition Chapter 10);

--- Added "pressure test icon" (see Chapter 12).

1 Scope

This standard specifies the delivery of natural gas, liquefied petroleum gas, dangerous liquids, highly volatile liquids, carbon dioxide pipeline pressure test practices.

This standard applies to the pipeline and pipeline components of the pressure test. Pipeline and pipeline facilities include. Line pipelines, yard pipelines, Pipeline appendages, plumbing fixtures, fittings, valves, fittings, etc.

This standard does not apply to pump sets, compressors, pressure relief cans, pressure vessels, control pipes, sampling pipes, instrumentation pipes, or other standard finger Components or piping systems required for pressure testing (eg, boilers and pressure vessels, piping systems covered by building standards, etc.).

This standard does not apply to the use of natural gas, nitrogen or air as a test pressure medium piping system pressure test.
