Corrugated steel pipes (CSP) are a highly versatile and durable solution for a wide range of applications, particularly in drainage and stormwater management. These pipes are known for their strength, longevity, and ability to withstand various environmental conditions. CSPs are available in multiple coatings and configurations to suit specific project needs.
For the corrugated metal pipe, the outside is soil corrosion, the inside is water and air corrosion.
Aabout soil corrosion, in my country, most of them is middle corrosion.
Air corrosion( ocea, industry, city, village）.
Non abrasion (level 1) no gravel and other moving material, all speed or rainwater pipe.
Low abrasion (level 2）with sand and gravel, speed lower than 1.6m/s.
Middle abrasion (level 3) with sand and gravel, speed 1.6~5.0m/s.
Harsh abrasion (level 4） harsh gravel or rock, speed faster than 5.0m/s.
Metal structure corrosion in fluid (water, seawater).

| Steel standards: | ASTM A36,EN 10111,ISO 5951 |
| Application | .Multiplate structures pipe can be used as: - culverts - bridges - tunnels - under passed - ecological crossing - pedestrian tunnel - hangers - shelter - warehouse - stores for ammunition - belt conveyor protection - ventilating duct - and for reinforcement and reconstruction of existing structures as well. Metal corrugated pipe can be used for every class of service load provided that appropriate back filling is performed |
