Mandates the continuous collection and analysis of inline inspection (ILI) data, pressure test histories, and cathodic protection records. ASME B31.4 Chapter IX
The compendium acts as a plain-language guide for every ASME standard referenced in the U.S. Code of Federal Regulations (CFR) . Instead of replacing the original codes, it provides technical excerpts and explanations to ensure compliance with federal law. : Directly maps ASME standards to: 49 CFR Part 192 : Natural and other gas transportation. 49 CFR Part 193 : Liquefied Natural Gas (LNG) facilities. 49 CFR Part 195 : Hazardous liquid pipeline transportation.
Successful pipeline deployment requires a holistic application of these standards across the asset lifecycle. Design and Material Selection asme pipeline standards compendium
): Safety multipliers that reduce allowable stress based on proximity to human population. For example, a gas pipeline in a desert may use a design factor of 0.72, while a pipeline near a housing development is restricted to 0.40 or lower.
Standards provide rigorous methods to verify MAOP after modifications, corrosion, or hydrostatic testing. Mandates the continuous collection and analysis of inline
The (officially PTB-9 ) serves as a comprehensive bridge between the ASME Standards and federal safety regulations in the United States. It is specifically designed to help operators and engineers navigate the complex requirements of 49 CFR Parts 192, 193, and 195 . Core Purpose and Scope
Utilizes a strict four-tiered "Location Class" system based on human population density near the pipeline. As population density increases from Class 1 (desert/farmland) to Class 4 (high-rise urban areas), the code mandates stricter design factors and lower allowable stress levels. ASME B31.8S: Managing System Integrity of Gas Pipelines Instead of replacing the original codes, it provides
The compendium is specifically designed to aid operators in complying with Title 49 of the CFR , focusing on three primary areas of pipeline safety: 49 CFR Part 192 : Transportation of Natural and Other Gas by Pipeline. 49 CFR Part 193 : Liquefied Natural Gas (LNG) Facilities. 49 CFR Part 195 : Transportation of Hazardous Liquids by Pipeline. The American Society of Mechanical Engineers - ASME Primary Standards Included
Recognizing the global shift toward alternative energy, establishes the standard for piping and pipelines that handle gaseous hydrogen, gaseous hydrogen mixtures, and piping for liquid hydrogen service . It is a companion to the other B31 codes but includes provisions specific to the unique challenges of hydrogen, such as hydrogen embrittlement.
Hydrocarbons, liquid petroleum gas (LPG), anhydrous ammonia, alcohols, and carbon dioxide.
Pipeline networks serve as the foundational infrastructure for global energy transportation, moving vast quantities of oil, gas, water, and chemical products across thousands of miles. To manage the immense pressures, environmental hazards, and structural demands of these networks, engineering teams rely on standardized technical frameworks. Chief among these is the American Society of Mechanical Engineers (ASME) digital ecosystem.
