Analysis for the reliability based design and evaluation method of natural gas pipeline

The natural gas pipeline engineering is growing rapidly, the emergence of new materials and solutions will bring reliability about the problem of the material, design, construction and operation; it needs to use the new design and evaluation method based on reliability. This paper introduces the principle and characteristics of the method, and through comparing it with the traditional method shows its superiority. At the same time, the research situations at home and abroad were reviewed in detail, and it illustrates the design and evaluation method of the research ideas and research focus, and the future prospects of the application were discussed.
