Corrugated steel pipe

Corrugated steel pipe is a type of pipe made from thin, ribbed sheets of steel that are formed into a corrugated shape and then joined together. This type of pipe is typically used for culverts, storm drains, and other types of underground infrastructure. It is durable, corrosion-resistant, and can withstand the weight of vehicles and other heavy loads.

There are several types of corrugated steel pipe available, including round, pipe-arches, and horizontal ellipse. The type of pipe used depends on the specific application and design requirements. Corrugated steel pipe can be coated with a protective layer to improve its durability and resistance to corrosion.

Corrugated steel pipe is widely used in a variety of construction and infrastructure projects due to its strength and durability. It is commonly used in road construction, bridge construction, and the construction of underground utilities. It is also used in irrigation and drainage systems, and can be used to convey water, sewage, and other types of fluids.

Corrugated steel pipe Size

The size of corrugated steel pipe refers to its diameter and length. Corrugated steel pipe is available in a range of sizes to suit different applications. The diameter of the pipe is measured in inches, and the length is typically specified in feet.

The size of the pipe needed depends on the specific application and design requirements. In general, larger pipes are used for culverts and other types of underground infrastructure, while smaller pipes may be used for irrigation and drainage systems or in the construction of bridge abutments and other structures.

Corrugated steel pipe is also available in a range of thicknesses to suit different applications. Thicker pipes are generally used for larger pipes or pipes that will be subjected to heavy loads or high levels of stress, while thinner pipes may be used for smaller pipes or pipes that will be used in less demanding applications.

It is important to choose the right size and thickness of corrugated steel pipe for the specific application to ensure that it is able to meet the necessary performance and design requirements.

Corrugated steel pipe Material

Corrugated steel pipe is typically made from galvanized steel, although it can also be made from aluminum, stainless steel, or other types of steel. Galvanized steel is a type of steel that has been coated with a layer of zinc to protect it from corrosion. This coating helps to extend the lifespan of the pipe and improve its resistance to rust and other forms of deterioration.

Steel

The thickness of the steel used in corrugated steel pipe depends on the specific application and design requirements. Thicker steel is generally used for larger pipes or pipes that will be subjected to heavy loads or high levels of stress. Thinner steel may be used for smaller pipes or pipes that will be used in less demanding applications.

Steel used for corrugated steel pipe is produced in accordance with Chinese standard.

Minimum yield strength 235N/mm2 and 345N/mm2

Steel standard Q235 and Q345

Also can accordance with EN10025

Steel standard S355JR, S235JR, S315MC

And can adopt the other standard steel according to customers’ demand

Corrugated steel pipe can also be coated with a protective layer to further improve its durability and corrosion resistance. This coating may be applied by the manufacturer or added on site during installation. Common coatings used on corrugated steel pipe include asphalt, concrete, and polyethylene. These coatings help to protect the steel from the environment and improve the overall performance of the pipe.

Depth of cover

The minimum allowable depth of cover is the largest of:

For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6（m）

For railways H=B/4 and not less than 0.6(m)

There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.

Durability

Corrugated steel pipe Application

Corrugated steel pipe is used in a variety of applications, including:

Road construction: Corrugated steel pipe is often used as a culvert under roads and highways. It can withstand the weight of vehicles and other heavy loads, making it a durable and reliable choice for this type of application.

Bridge construction: Corrugated steel pipe can be used in the construction of bridge abutments, foundations, and other structural components. Its strength and durability make it a suitable choice for this type of application.

Underground utilities: Corrugated steel pipe is commonly used in the construction of underground utilities such as water and sewage pipes, electrical conduits, and gas lines. Its corrosion-resistant properties make it well-suited for this type of application.

Irrigation and drainage: Corrugated steel pipe is often used in irrigation and drainage systems to convey water and other fluids. It is durable and can withstand the forces of flowing water, making it a suitable choice for this type of application.

Environmental protection: Corrugated steel pipe can be used in the construction of retention basins, sediment basins, and other structures designed to protect the environment. Its strength and durability make it a suitable choice for this type of application.

Multiplate structures can be used for every class of service load provided that appropriate backfilling is performed. As: Culverts; 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.

Corrugated steel pipe Type

There are several types of corrugated steel pipe available, including:

Round: Corrugated Round Metal Pipe (CMP, CSP, CASP,CAP) is shaped like a cylinder and is typically used for culverts and other types of underground infrastructure.

Pipe-arches: Pipe-arches(CMPA, CSPA, CASPA, CAPA) are shaped like an arch and are used in the construction of bridges and other structures. They can span large distances and are able to withstand heavy loads.

Horizontal ellipse: Horizontal ellipse corrugated steel pipe is shaped like an ellipse and is often used in the construction of underground utilities. It has a high level of structural stability and is able to withstand the forces of flowing water.

Flared end section: Flared end section corrugated steel pipe is designed with a flared end that allows it to be easily connected to other pipes or structures. It is often used in the construction of culverts and other types of underground infrastructure.

Banded: Banded corrugated steel pipe is made with a band of steel around the circumference of the pipe, which adds additional strength and stability. It is often used in the construction of bridge abutments and other structures that are subjected to heavy loads.
