ASME B31.8S-2001 pdf free download.MANAGING SYSTEM INTEGRITY OF GAS PIPELINES.
This Standard applies to on-shore pipeline systerms constructed with ferrous materials and that transport gas. Pipeline system means all parts of physical facilities through which gas is transported, including pipe, valves. appurienances allached tu pipe, compressor units, meter- ing stations, regulator stations, delivery stations, holders and fabricaicd assemblies. The principles and processes embodied in integrity management arc applicablc to all pipeline systems. This Standard is specifcally designed to provide the operator (as defined in section 13) with the information necessary to develop and implement an effective integ- rity management program utilizing proven industry prac- tices and processes. The processes and approaches within this Standard are applicable to the entire pipeline systcm. 1.2 Purpose and Objectives Managing the integrity of a gas pipeline system is the primary goal of every pipeline system operator. Operators want to continue providing safe and reliable delivery of natural gas to their customers without adverse effecls on employees, the public. customers. or the environment. Incident-free operation has been and continues to be the gas pipeline indusuy’s gual. The usc of this Standard as a supplement to the ASME B31.8 Code will allow pipeline operators to move closer to that goal. A comprehensive, systematic, and integrated integrity management program provides the means to improve the safety of pipeline systems. Such an integnity manage- ment program provides the information for an operator to effectively allocate resources for appropriate preven- tion, detection, and mitigation activities thal will result in improved safety and a reduction in the number of incidents. This Standard describes a process that an operator of a pipeline system can use to assess and mitigate risks in order to reduce hoth the likelihood and conse- quences of incidents. It covers both a prescniptive- and a performance-based integrity management program.
The prescriptive process, when followed cxplicitly, will provide all the inspcction, prevention, detection, and mitigation activities necessary to produce a satisfactory integrity management program. This does not preclude conformance with the requirements of ASME B31.8. The performance-based integrity management prngram alternative utili7es more data and more extensive risk analyses, which enables the operator to achieve a greater degree of flexility in order to meet or exceed the requirements of this Standard specifcally in the areas of inspection intervals, wois used and mitigation uechniques employed. An operator can not proceed with the per- fomance-based intcgrity program until adequate inspec- tions arc performcd that provide the information on the pipeline condition required by the prescriptive- based program.’ The level of assurance of a performance . based program or 2n lternative international Standard must meet or exceed that of a prescriptive program. The requirements for prescriptive- and performance- based integnity management programs are provided in each of the sections in this Standard. In addition, Nonmandatory Appendix A provides specific activities by hreat categories, that an opcrator shall follow in order lo produce a satisfactury prescripive integrity management program. This Standard is intended for use by individuals and teams charged with planning, implementing, and improving a pipeline integnity management program. Typically, a team will include managers, engineers, operating personnel, technicians and/or specialists with specific experise in prevention, detection, and mitiga- tion activities. 1.3 Integrity Management Principles A set of principles is the basis for the intent and specific details of this Standard. They are enumerated here so that the user of this Suandard can understand the breadth and depth to which integnity shall be an integral and continuing part of the safe operation of a pipeline system.ASME B31.8S pdf download.
