Abstract: Practice proves that control of valve technology is one of the "weakest link" in present oil and gas pipeline engineering. By means of exploring and studying the origin, definition, property, characteristic and function of valve commissioning, and analyzing its development status quo at home and abroad, the authors consider that valve commissioning can effectively solve the problem of "short plate" existed in pipeline engineering system, improve the valve technology of oil and gas pipeline engineering, lower in the risk in pipeline commissioning and operation, increase operation quality and enrich integrity management content of pipeline.
