ASME B31.4-2022 is a comprehensive standard that provides requirements for the design, materials, construction, assembly, inspection, testing, operation, and maintenance of liquid pipeline systems. It covers pipelines transporting liquids and slurries between various facilities, including production fields, storage facilities, and terminals

This standard is essential for engineers, operators, and managers involved in pipeline systems for liquids and slurries, including those working in production fields, tank farms, natural gas processing plants, refineries, and pump stations

ASME B31.4-2022 covers pipelines transporting liquid petroleum, liquid anhydrous ammonia, and aqueous slurries of nonhazardous materials such as coal and mineral ores

The standard governs design requirements for pipeline systems that transport liquid or aqueous slurries of non-hazardous materials. It includes primary and auxiliary piping at pipeline terminals, tank farms, pump stations, and metering stations

The standard excludes building services piping, pressure vessels, heat exchangers, pumps, meters, and piping used in oil wells and wellhead assemblies

While both are pipeline design codes, ASME B31.4 deals with liquids and slurries, whereas ASME B31.8 focuses on gas transmission and distribution

ASME B31.4 covers pipelines with temperatures above -30°C, with a maximum metal temperature limit of 120°C

The allowable stress is dependent only on the specified minimum yield strength of the pipe material

The maximum value of the design factor F in thickness calculations is 0.72, though lower values can be used depending on service and location requirements

The 2022 edition includes revised allowable expansion stress alignments, new references to API 1133, clarifications on cast iron distinctions, and updated etchant composition guidelines

ASME regularly reviews and updates its standards. The frequency of updates can vary, but users should always refer to the most current version for compliance

To ensure compliance, thoroughly review the standard, implement its requirements in your pipeline design and operations, and stay updated on any interpretations or addenda issued by ASME.

While ASME B31.4-2022 is widely recognized internationally, always check local regulations and standards that may apply to your specific project location.
