P-93: Guideline for Piping Failure Rates in Nontoxic Cryogenic Gas Supply Systems

Abstract

This publication applies to piping up to and including 6-inch pipe size of 300 series austenitic stainless steels and when the design pressure stress of the pipe does not exceed one half of the basic allowable stress. The use of this publication is intended for light industrial sites. Risks from outside threats to piping, if present, should be considered separately. Near retail or light industrial areas are defined as areas where the size of the piping and major equipment in the designed system are same or larger than any adjacent or neighboring systems. Neighboring or adjacent systems of larger diameter or larger components where the maintenance setbacks or defined risk area overlaps would disqualify the site as near retail or light industrial. Additionally, near retail areas are often inherently closer to the public.

For more details on the development of this methodology, see CGA TR-7, Methodology to Determine Piping Failure Rates for Nontoxic Cryogenic Industrial Gas Supply Systems with Pipe Size Up To 6 Inches.
