Assembled Corrugated Pipes in Various Shapes
An assembled corrugated pipe is composed of arc corrugated steel plates that are bolted together to form the required shape. It is generally used when the maximum sizes of integral corrugated pipes or spiral corrugated pipes is exceeded or where the height of cover material is so great that traditional corrugated pipes cannot meet the construction requirements.

Features:
A part of assembled corrugated steel pipe consists of several corrugated plates.
Assembled corrugated steel pipe allows for easy installation - just bolting corrugated plates together.
Lightweight and nestable structure allows for easy handling and transport.
Load pressure is well-distributed to prevent deformation, especially damages to bridges and culvert caused by frost in north cold regions.
Heavy zinc coating ensures great rust and corrosion resistance as well as a longer lifespan.
Improve safeness of vehicles by maintaining flat road surface and ameliorating the slab staggering in interlocking areas between soft soil foundations and embankment.
Easy to install due to mounting holes are pre-drilled on each side of corrugated plates according to your requirements.
Shorter working periods as the project construction and pipe assembly can be carried out separately.
Low requirements to bearing capacity and planeness of soil foundations.
Cost saving due to low transport cost, low labor cost and low maintenance cost, etc.
Economical for bridge construction and replacement.
Providing more environment protection as traditional construction materials such as sand, wood and stones are decreased significantly.
Curved plates in different radii are marked for easy identification.
Assembly drawings and instructions are enclosed for providing helpful guidance to installers.
