scope:

The scope of this Manual includes all pipelines within the scope of the pipeline codes that are part of ANSI/ASME B31 Code for Pressure Piping: i.e., ANSI/ASME B31.4, Liquid Petroleum Transportation Piping Systems; ANSI/ASME B31.8, Gas Transmission and Distribution Piping Systems; and ANSI/ASME B31.11, Slurry Transportation Piping Systems.¹ Parts 2, 3, and 4 are based on material included in ASME Guide for Gas Transmission and Distribution Piping Systems.

This Manual is not applicable to new construction covered under the B31 Code Sections. That is, it is not intended that this Manual be used to establish acceptance standards for pipe that may have become corroded prior to or during fabrication and/or installation.

This Manual is intended solely for the purpose of providing guideline information for the designer/ owner/operator. Thus, the specific use of this Manual is the responsibility of the designer/owner/ operator.
