Applicability and Economy of Three Kinds of Gathering Transportation Pipelines in an Oilfield

The gathering and transportation pipelines made of 16Mn in an oil field corroded seriously, resulting in frequent occurence of accidents. The corrosion rates, lifetimes and economy of 06Cr13 pipe and 20G/316L clad pipe were determined according to the results of field experiment. The results show that 06Cr13 pipe is the most economical among the three types of pipes under field condition.
