Research on Design and Construction Issues of Oxygen Pipeline in Chemical Plant

摘要

When the high-pressure chemical oxygen delivery device, the slightest mistake, likely to cause explosion, so the design oxygen pipeline, it is usually as a special danger medium piping design. This paper explores the design of the petrochemical industry in oxygen pipes, installation and construction unit issues and process piping installation and construction issues, systematic analysis of the piping in the design and construction should pay attention to the problems and solutions to ensure each petrochemical industry aspects of safe operation. Standard requirements and corresponding measures in aspects of oxygen pipeline flow rate control, material selection, pipe and valve selection and pipeline construction, which should be followed to ensure the safety of oxygen pipeline, which are described in details, according to the national standard/safety technical regulation for oxygen and relative gases produced with cryogenic method. Finally, the experience of safe use of oxygen pipelines is presented.
