What Are the Advantages of Spiral Corrugated Steel Pipe?

Helical corrugated steel pipe is a continuous circular tubular body formed by rolling a galvanized steel strip into a certain wave shape, and then bending and slanting the spiral to make the edges of the steel strip interlock with each other. Spiral corrugated culvert is also called corrugated pipe culvert, which refers to the corrugated pipe used for culverts buried under highways and railways. It is a circular corrugated pipe made of corrugated steel plate rolled or made of corrugated steel plate. Spiral corrugated culvert is widely used in highways, railways culverts, passages, small bridges, tunnels, temporary access roads, drainage pipes and various mine roadways Retaining wall support and other projects.

Spiral corrugated steel pipe was invented by the United States in 1896 and has been used for more than one hundred years. It is an ideal substitute for cement pipes and reinforced concrete structures. The structure of the spiral corrugated steel pipe is reasonably stressed, the load is evenly distributed, and has a certain resistance to deformation, which can solve the problem of damage to the bridge and pipe culvert concrete structure in the cold northern area (frost). Improve driving safety; reduce post-construction operation and maintenance costs; the actual engineering cost of spiral corrugated steel pipe is also lower than that of similar span bridges and culverts; spiral corrugated steel pipe has its unique advantages and strong adaptability, replacing the traditional The products have broad application prospects.

Features of Spiral Corrugated Pipe

High compressive strength: 1.5-5 times that of cement pipes of the same caliber.

Light weight and convenient transportation: 1/5～1/10 of the weight of the cement pipe of the same caliber:

Fast construction: the pipe section is long (adjustable from 3 to 12 meters), and the clamp is quickly connected.
