Features of Corrugated Steel Pipes

It is beneficial for enterprises to apply corrugated steel pipes with flexibility and high strength based on analysis of relations among materials, structure and function. Because of the axial corrugation, pipes have excellent force characteristics. Besides, the stress and strain caused by the load are simultaneously distributed in the axial and radial direction, to well prevent deformation to a greater extent, and make the most of the steel structure.

Corrugated steel pipes enjoy advantages of a short construction period, lightness, convenient installation, good durability, low engineering and maintenance cost, and strong resistance to deformation. The corrugated steel pipe is characterized by:

1) Excellent adaptation to foundation deformation. There are low requirements for bearing capacity and planeness of soil foundations, and the actual project cost is close to or lower than the similar kind of pipes built in bridges and culverts.

(2) Shorter working periods, as the project construction and pipe assembly can be carried out separately.

(3) Concentration of production, which is not affected by the environment and is conducive to cost reduction and quality control.

(4) Ease in installation due to less adoption of large equipment.

(5) Providing solutions, especially for the damage to bridges and culvert caused by frost in north cold regions.

(6) Providing more environmental protection as the use of traditional construction materials such as cement, sand, wood and stones is decreased significantly.

(7) Even distribution of load pressure to prevent deformation

(8) Standardized design to ensure efficient production and straightforward installation within shorter production period.

(9) Providing solutions to “faulting of slab ends” to improve the comfort and safety of driving, and reduce post-construction operation and maintenance costs.
