Metal Corrugated Culvert - Chinaprice: 1.00 Dollar US$
1.Multiplate structures pipe can be used as:
- under passed
- ecological crossing
- pedestrian tunnel
- stores for ammunition
- belt conveyor protection
- ventilating duct
- and for reinforcement and reconstruction of existing structures as well.
Corrugated steel culvert can be used for every class of service load provided that appropriate backfilling is performed.
Corrugated steel culvert used for mltiplate structure 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
Corrosion resistance of steel is the main factor deciding about the durability of steel structures. Long-term tests done in many countries of world have proven that, the proper corrosion protection of the steel structure let to prolong the life time of structures. Durability of structures built with use of multiplate 150 corrugated steel pipe designed for the zinc coatings give the so-called cathode protection. Thanks to this they can protect the steel also in electrochemical way achieving the multi-elemental corrosion protection system.
Attention: in strong corrosion environment, we suggest hot-dip plastic on the galvanization, plastic thick 0.3mm, (single face dip), the durability is more than 100 years.
When designing the structure plate corrugated steel pipe durability should be considered with regards to:
- zinc coatings
- paint coatings
-sacrificial thickness of steel as allowance for corrosion
(increasing of the plate thickness)
- other kinds of protections
Corrugated steel pipe is necessary to remark that the corrosion points appear most often in the bottom part, where the stress level in the steel structure is the lowest. It means that by designing the structure according the most stressed cross-section-the upper sphere, there is an additional security reserve in scope of the structure durability.
System of corrosion protection duplex
For longer structure durability (especially in agressive environment) there is a possibility of the additional corrosion protection by epoxy painting. Protection of structure both with zinc coating and epoxy coating creates duplex system. Also, after assembly Corrugated steel culvert, we can make the duplex corrosion protection according to customers request color and materials.
