Steel corrugated pipe culvert in China from the experimental study of early 1998 to promote the use of so far, after more than 10 years of time, the application of different grade highway construction in more than 20 provinces, autonomous regions, municipalities, This structure with its excellent performance won the favor of road builders, closed section form has been successfully applied to 12 meters, the application of non closed section form to span 7.4 meters.The top tube filling height from 0.6m has been successfully applied to 56m.
for the corrugated metal pipe, the outside is soil corrosion, the inside is water and air corrosion
about soil corrosion, in my country, most of them is middle corrosion.
air corrosion( ocea, industry, city, village）
