ASME B31.4-2022

説明

ASME B31.4 is a standard developed by the American Society of Mechanical Engineers (ASME) that pertains to the design, construction, inspection, operation, and maintenance of pipeline systems for natural gas and petroleum.

1. Scope of Pipeline Systems: ASME B31.4 primarily applies to pipeline systems for natural gas and petroleum. This includes the transportation of oil, petroleum products, liquefied petroleum gas (LPG), and more.
2. Design: The standard specifies design requirements for pipeline systems, including dimensions, thickness, materials, welding, and other relevant design parameters. The design should consider various loads and environmental conditions that the pipeline may encounter during operation.
3. Construction and Installation: The standard provides guidelines for the construction and installation of pipeline systems, including welding, inspection, pressure testing, and other requirements. Construction processes must adhere to the stipulations in the standard to ensure the safety and reliability of the pipeline system.
4. Inspection and Testing: The standard requires inspection and testing of pipeline systems to ensure compliance with design and performance requirements. This includes non-destructive testing of pipelines and welds, as well as pressure testing.
5. Operation and Maintenance: ASME B31.4 includes guidance on the operation and maintenance of pipeline systems. This involves regular inspections, maintenance activities, and repairs to ensure the safe operation of the pipeline system throughout its service life.
