1. Introduction
Natural gas is one of the most widely used energy sources in the world. It is an important fuel for transportation because of its low emissions and higher efficiency compared to other sources. In order to use natural gas in vehicles, a compressor is needed to pressurize the gas to the proper levels. The Regulator for Compressed Natural Gas (QC/T 671-2000) is responsible for regulating this pressure in a safe and reliable manner. This article provides an overview of the QC/T 671-2000 Standardization, including its purpose, scope, structure and content.
2. Purpose
The purpose of the QC/T 671-2000 Standardization is to ensure that the Compressed Natural Gas (CNG) used for transportation meets the necessary safety and quality standards. The Standardization establishes requirements for the Compressor Regulator that is used to control and regulate the pressure of the CNG. The Regulator also ensures that the CNG is supplied at the correct pressure for the particular application.
3. Scope
The scope of the QC/T 671-2000 Standardization includes the design, manufacture and performance of the Compressor Regulator used for Compressed Natural Gas in transportation. The Standardization applies to all CNG transportation vehicles using the Compressor Regulator and covers the performance requirements, construction, installation and maintenance of the Regulator. The Standardization also covers the supplementary parts used with the Regulator, such as relief valves, fittings and connectors.
4. Structure and Content
The QC/T 671-2000 Standardization is divided into seven main parts, which cover the following topics:
• Scope and Purpose
• Technical Requirements
• Design
• Testing
• Quality Assurance
• Labelling
• Maintenance
The Technical Requirements section describes the requirements for the design, manufacture, performance and installation of the Compressor Regulator. The Design section outlines the design requirements for the Regulator and its components. The Testing section describes the tests that must be performed on the Regulator before it is used. The Quality Assurance section outlines procedures for ensuring the quality of the Regulator and its components. The Labelling section describes the labelling and marking requirements for the Regulator and its components. The Maintenance section outlines requirements for the proper operation and maintenance of the Regulator.
5. Conclusion
The QC/T 671-2000 Standardization is the primary Standardization used for regulating the Compressed Natural Gas in transportation. It outlines the requirements for the design, manufacture, performance, installation and maintenance of the Compressor Regulator used with CNG. Through the implementation of this Standardization, CNG vehicles are able to operate safely and efficiently.
