In the United States, both liquid and gas p

36、ipeline operators have been working with their regulators for several years to develop a more systematic approach to pipeline safety integrity management. The gas pipeline industry needed to address many technical concerns before an integrity management standard could be written. A number of initiat

37、ives were undertaken by the industry to answer these questions; as a result of two years of intensive work by a number of technical experts in their fields, 20 reports were issued that provided the responses required to complete the 2001 edition of this Code. (The list of these reports is included i

38、n the reference section of this Code.) This Code is nonmandatory, and is designed to supplement B31.8, ASME Code for Pressure Piping, Gas Transmission and Distribution Piping Systems. Not all operators or countries will decide to implement this Code. This Code becomes mandatory if and when pipeline

39、regulators include it as a requirement in their regulations. This Code is a process code that describes the process an operator may use to develop an integrity management program. It also provides two approaches for developing an integrity management program: a prescriptive approach and a performanc

40、e- or risk-based approach. Pipeline operators in a number of countries are currently utilizing risk-based or risk-management principles to improve the safety of their systems. Some of the international standards issued on this subject were utilized as resources for writing this Code. Particular reco

41、gnition is given to API and their liquids integrity management standard, API Std 1160, which was used as a model for the format of this Code. The intent of this Code is to provide a systematic, comprehensive, and integrated approach to managing the safety and integrity of pipeline systems. The task

42、force that developed this Code hopes that it has achieved that intent. The 2004 Supplement was approved by the B31 Standards Committee and by the ASME Board on Pressure Technology Codes and Standards. The 2010 Supplement was approved by the B31 Standards Committee and by the ASME Board on Pressure T

43、echnology Codes and Standards. The 2012 Edition of the Supplement was a compilation of the 2010 Edition and the revisions that occurred following the issuance of the 2010 Edition. The 2014 Edition of the Supplement was a compilation of the 2012 Edition and the revisions that occurred since the issua

44、nce of the 2012 Edition. The 2016 Edition of the Supplement is a compilation of the 2014 Edition and the revisions that have occurred since the issuance of the 2014 Edition.
