We are the professional manufacturer of spiral pipe, corrugated metal culvert pipe, corrugated steel culvert pipe, steel culvert, corrugated metal culvert, arch corrugated steel pipe and highway corrugated steel pipe culverts in China. They all have wide range of applications in industrial areas.
Method of proceeding when calculating the durability of multi-elements steel structure type multiplate MP150:
- define function of structure.
- define of the required durability of the structure
- define of conditions of the environmental aggressiveness(water, backfill, air) - choice the governing corrosion model.
- specifying of the plate thickness with regards to static calculations(acc. to Sundquist - Petterson method)
- specifying of corrosion protection(thickness of zinc coating, paint coating, paved bottoms, etc)
- define of protection layers in upper and lower sphere of the structure with allowance the corrosion progress in surrounding environments with described aggressiveness.
- calculation of durability period of the structure in upper and lower part.
- comparison of the structure durability in the critical parts with the required value.
- decision about acceptance of the structure or about rejection and change of parameters of corrosion protection.
