第1章 概述随着社会经济的发展和人民生活水平的提高，管道燃气逐渐成为人

Chapter 1 Overview <br>With the social and economic development and improve people's living standards, piped gas is becoming an important part of people's daily lives, how to ensure the safe operation of the gas pipeline has become an important issue, although the gas is a clean resource, but once leak occurs, it can easily lead to all kinds of accidents occur. Therefore, to ensure the safety of gas pipeline (that is, the quality of gas pipeline projects) in order to better guarantee the people more convenient and safer to use pipeline gas. But the quality of the gas pipeline project and gas pipeline project is determined by its own characteristics. Therefore, to make effective quality management costs, we must proceed from reality, objective analysis of the gas pipeline project design features and application characteristics, can be targeted to achieve effective management of the gas pipeline project.

Chapter 1 Overview<br>With the development of social economy and the improvement of people's living standard, pipeline gas has gradually become an important part of people's daily life, how to ensure the safe operation of pipeline gas has become an important issue, although gas is a clean resource, but once the leakage, it is very easy to lead to all kinds of accidents. Therefore, to ensure the safety of pipeline gas (i.e., the quality of gas pipeline projects), in order to better ensure that the people more convenient and more safe use of pipeline gas. However, the quality of gas pipeline project is determined by the characteristics of pipeline gas project itself. Therefore, in order to do a good job in the effective management of cost quality, we must start from the actual, objective analysis of the design characteristics and applicable characteristics of pipeline gas project, in order to achieve effective pipeline gas project management.

Chapter 1 Overview<br>With the development of social economy and the improvement of people's living standards, pipeline gas has gradually become an important part of people's daily life. How to ensure the safe operation of pipeline gas has become an important issue. Although gas is a clean resource, once leakage occurs, it is very easy to cause various accidents. Therefore, to ensure the safety of the pipeline gas (i.e. the quality of the gas pipeline project), we can better ensure that the people use the pipeline gas more conveniently and safely. But the quality of gas pipeline engineering is determined by its own characteristics. Therefore, in order to effectively manage the cost and quality, it is necessary to objectively analyze the design characteristics and applicable characteristics of the pipeline gas engineering from the reality, so as to achieve the effective management of the pipeline gas engineering.
