GB/T 34347-2017 in English

Introduction

Cryogenic insulated gas cylinders are important equipment for storing and transporting cryogenic liquefied gases, and are widely used in industry, medical treatment, scientific research and other fields. With the expansion of its application scope, it is particularly important to ensure the safety and reliability of cryogenic insulated gas cylinders. The standard GB/T 34347-2017 "Periodic Inspection and Evaluation of Cryogenic Insulated Gas Cylinders" provides detailed technical specifications and evaluation methods for the periodic inspection of such gas cylinders.

Background of Standard Formulation

With the widespread application of cryogenic insulated gas cylinders in various industries, their safety issues have gradually become the focus of attention. In order to standardize the inspection process of cryogenic insulated gas cylinders and ensure their long-term safe use, the National Technical Committee for Standardization of Gas Cylinders organized the drafting of this standard. This standard was issued in 2017 and replaced the old version of the standard, further refining the inspection requirements and technical indicators.

Comparison of standard frameworks

Explanation of professional terms

Static evaporation rate: The evaporation rate of the medium in the gas cylinder under specified conditions. GB/T 18443.5 provides a test method.

Interlayer insulation performance: The insulation effect provided by the multi-layer structure between the gas cylinder shell and the liner directly affects the safety and service life of the gas cylinder.

Implementation Suggestions

Conclusion

GB/T 34347-2017 is The regular inspection of class=instrument>cryogenic insulated gas cylinders provides comprehensive technical guidance to ensure their safety and reliability. By strictly implementing the standard requirements, the service life of the equipment can be effectively extended and potential safety accidents can be avoided.
