Doc. 217/19Vacuum-Jacketed Piping in Liquid Oxygen Service

In recent years, the increase in the size and production capacity of air separation plants has led to a corresponding increase in the capacity of liquid oxygen storage and transfer installations at production sites.

Multiple violent ruptures of vacuum-jacketed piping systems used in liquid oxygen service have been experienced in the industrial gas industry. These incidents have occurred due to a variety of causes.

The intent of this publication is to ensure that a minimum, uniform level of safety is provided throughout the industrial gas industry for the protection of the public and industry employees.

This publication addresses vacuum-jacketed piping used in any stationary industrial gases applications including air separation plants, other industrial gases facilities, and customer installations in liquid oxygen service.

This publication provides guidance to those persons directly associated with the design, installation, operation, and maintenance of vacuum-jacketed piping systems used to transfer liquid oxygen.

The publication is part of the programme to develop Globally Harmonised publications amongst Regional Gas Associations.
