Requirement and Standard For The Steel Silo Wall

1.Steel silo shall meet the structural calculations require corrosion of steel and fly ash, grain storage on the wall of the silo, the number of roof stiffener should not be less than 25% of the total, stiffeners joints should not be at the same level.

2.Corrugated steel silo wall joints and connecting bolt holes, corrugated steel, welded steel silo wall, the vertical seam of the adjacent two upper and lower siding should be staggered layout. Welding steel staggered distance should not be less than 250mm., Seal, seal should be set.

3.Steel silo on the basis of silo, should still consider the external environment, and take appropriate measures.

4.Two adjacent height. To the vertical stiffener joints should be used to connect the same strength.

5.Vertical stiffeners should be placed inside the silo silo wall. Steel silo wall should not be set horizontal support, ladder and other wall devices. 6, when the use of welding connections, the height of the weld is taken to be thinner welded steel wall thickness; helical crimping bite mouth up and down the weld seam length should not be less than 50mm. Welding the outer surface of the welding silo wall must be preserved deal with.

7.Spiral hemming steel silo should adopt high-frequency welding bolt connection; bolt diameter and number should be calculated and determined, the diameter should not be less than 8mm, the spacing should not be greater than 200mm; vertical stiffener and silo wall connection: Corrugated steel silo should adopt plating Zinc bolt connection

8.Door and silo wall, door and door frame connection, should take sealing measures. Entrance hole should be located inside and outside the two layers, respectively, to the steel silo inside and outside the open.
