Abstract: With the continuous growing demand for natural gas, China's high-grade oil and gas pipeline construction has developed rapidly and ranked in the international leaders. In the application process of high-grade oil and gas transmission pipes, the technical support system for product development and engineering application has performed an important function. The technical support system is composed of four parts: quality supervision and evaluation, standardization, scientific research and failure analysis. Each part was elaborated from connotation, development history and current situation. The technical support system has played an important role in the development and engineering application of China's oil and gas pipeline industry, as well as in the development and engineering construction of X80 pipe products for China-Russia Eastern Gas Pipeline Project. The system will continuously provide technical support for construction of intrinsically safe pipeline engineering.
