Types of steel corrugated culverts mainly include the following:
Classification by assembly method:
Integrated corrugated culvert: This type of corrugated pipe is manufactured as a whole and does not require additional assembly work.
Assembled corrugated culvert: This type of corrugated pipe is spliced by multiple parts and needs to be assembled on site.
Classification by shape:
Circular: This type of corrugated pipe is widely used in highway and railway culverts.
Oval: Oval corrugated pipes are also used in specific projects.
Horseshoe: This shape of corrugated pipe is suitable for specific engineering needs.
Arch: Arched corrugated pipes perform well in specific engineering environments.
Classification by connection method:
Internal flange connection: Connection is made through the internal flange, which is suitable for connection scenarios that require high strength.
External flange connection: Connection is made through the external flange, which is suitable for scenarios that require stable connection.
Plate overlap : Connection is made by overlapping the plates, which is suitable for scenarios that require flexible connection.
Clamp connection : Connection is made by clamps, which is suitable for scenarios that require quick installation .
Classification by processing method :
Steel strip rolling and spiral curling into a circle and welding : Processed by rolling and spiral curling.
Bite-jointed spiral steel pipe : Formed by bite-joining.
Two-step corrugated pipe by pressing and corrugating : Processed by pressing and corrugating .
