ASME B31.3 Process Piping Code Overview

Process Piping Code Overview

ASME B31.3

ASME B31.3 is a process piping code that provides guidelines for the design, fabrication, installation, and testing of process piping systems.

Scope:

• Applies to piping systems that transport fluids, including liquids and gases, in petroleum refineries, petrochemical plants, and other process facilities.
• Covers piping systems outside of power boilers and electric generating stations.

Key Requirements:

• Material Selection: Specifies requirements for piping materials, including mechanical properties, testing, and certification.
• Design: Covers piping layout, flexibility, and support, as well as calculation methods for pipe stress and flexibility.
• Fabrication and Installation: Provides guidelines for welding, bending, and assembly of piping components.
• Testing and Inspection: Outlines procedures for hydrostatic testing, pneumatic testing, and non-destructive examination.
