spiral metal pipe
China has built 68,000 km of oil and gas pipeline line. During its construction, due to engineering suspension, construction surplus, engineering standby and other factors, large diameter steel pipe is often stored in the open air.If the open-air storage time is longer, it will appear such as corrosion pit, corrosion after the wall thickness thinning, anti-corrosion layer warped, anti-corrosion layer aging and other problems, will cause the use of steel pipe degradation, waste or re-treatment, resulting in a waste of resources.Mainly is the steel tube tube body does not have the cover, the cover protection is not ideal, does not have the support, part is piles up the layer number excessively the question, also has the coastal area mostly belongs to the Marine climate, the annual rainfall is big, the air humidity is big, the steel tube and the steel tube contact place ponding and so on causes.
