The corrosion behaviors of different material in the condensate water from the natural gas purifying station were studied by laboratory tests, field tests and measurements of polarization curve. The results showed that hot dipping aluminum steel had a good corrosion resistance to the accompanying gas of crude oil and condensate water in the natural gas purifying station.

A new steel matrix wear resistant composite reinforced by in situ granular eutectics can be obtained by modifying with a Si-Ce-Ti compound in the steel melt. The result indicates that the in situ granular eutectic is a pseudo-eutectic of austenite and (Fe, Mn)3C, which is formed between austenite dendrites during solidification due to the segregation of C and Mn impelled by modifying elements. The quantity of in situ granular eutectic reaches up to 8% 12%, and its grain size is in the range from 10μm to 20μm. The austenite steel matrix wear resistant composite reinforced by in situ granular eutectic (abbreviated AGE composite) and austenite-bainite steel matrix wear resistant composite reinforced by in situ granular eutectic (abbreviated ABGE composite) are obtained in the as-cast state and by air hardening, respectively. The wear resistance of the AGE and ABGE composites can be more greatly increased than that of their matrix steels under low and medium impact working condition.
