Multi-plate corrugated steel pipe (MPCSP) is a type of corrugated metal pipe that is used for the drainage of water and other liquids. MPCSP, also referred to as sectional place or structural plate, is called for when the maximum size of corrugated pipe is exceeded or where greater or differential thicknesses are required.
YITONG Corrugated offers a variety of plate products allowing for large spans, extreme fill heights, and other unique applications.
Multi-plate corrugated steel pipe (MPCSP) is made by joining multiple sheets of metal together using a series of plates and bolts. The sheets of metal are rolled into a wave-like shape, and the plates and bolts hold the sheets together to form a tube. The corrugations, or waves, in the metal provide additional strength and rigidity to the pipe, making it more resistant to damage and collapse. Generally used in flood control and sewer systems, they have also been successfully used for pedestrian passages and overhead conveyor covers.
MPCSP is commonly used in the construction of drainage systems for roads, highways, and other infrastructure projects. It is also used in the construction of culverts, which are structures that allow water to flow underneath roads or other obstacles. In addition to its use in drainage systems, MPCSP is also used in a variety of other applications, including irrigation, water supply, and sewage systems.
One advantage of using MPCSP is that it can be easily assembled on site, as it does not require welding. This makes it well-suited for use in remote locations or in situations where welding equipment is not available. Additionally, MPCSP is resistant to corrosion, which makes it an ideal choice for use in outdoor and underground applications.
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.
