ASME B31.4 – Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids

asme.b31.4.2002

ASME B31.4 is a code developed by the American Society of Mechanical Engineers (ASME) that addresses the design, construction, operation, and maintenance of pipeline transportation systems for liquid hydrocarbons and other liquids. Here are some key points about ASME B31.4:

Scope:

ASME B31.4 specifically focuses on pipeline systems used for the transportation of liquid hydrocarbons, including crude oil and petroleum products, as well as other liquids. These pipelines are typically used in the oil and gas industry.

Applicability:

This code applies to onshore liquid pipeline systems, including pump stations, compressor stations, and terminals. It covers various aspects of the pipeline, such as materials, design, fabrication, inspection, testing, and operation.

Key Requirements:

Materials: ASME B31.4 provides guidelines for selecting and specifying materials suitable for liquid pipeline systems, considering factors such as pressure, temperature, and the characteristics of the transported liquids.
Design: The code outlines design criteria for the pipeline and its components, including considerations for pressure, temperature, loads, and safety factors. It also includes provisions for external loads such as soil and environmental conditions.
Fabrication and Construction: ASME B31.4 includes requirements for the fabrication and construction of liquid pipeline systems, ensuring that they meet the specified standards for integrity and reliability.
Inspection and Testing: The code specifies procedures for inspecting and testing pipeline components to verify compliance with design and construction requirements.
Operation and Maintenance: ASME B31.4 provides guidelines for the safe operation and maintenance of liquid pipeline systems, including considerations for leak detection, corrosion control, and integrity management.

Compliance:

Liquid pipeline systems in many jurisdictions are required to comply with ASME B31.4 to ensure the safety and reliability of these systems.

It’s important to check for the latest edition and any revisions of ASME B31.4 on the official ASME website or other authoritative sources for the most up-to-date information.
