WHY NOT PIPE CULVERT?
POPULAR OPINION DOESN'T MAKE IT RIGHT.
There is a popular school of thinking surrounding the question of round shelters vs square shelters. There is no shortage of people and even "professionals" that will claim that a round shelter offers more strength than a square shelters. This couldn't be further from the truth. It's easy to trace the origins of this pop-culture thinking back to the Roman arch style of engineering. At the time - this style of architecture was cutting edge and far stronger than anything else. However; just as time has progressed bringing new ideas and technology; so in like fashion has our understanding of engineering grown. Round is NOT stronger than everything else.
Steel Silos Specification
Material of the profile: 195-235Mpa GI or carbon steel

Profile height (h): from 13±1mm
Effective width (b): 912±4mm
Flange height (c): 76±2mm
Perforated round or oval holes for at least the following screw diameter must be confirmed by customer before order
Length tolerance: ±1.5mm per each pieces
Features
1. Large capacity
One single-silo capacity is up to 17,000 tons with comprehensive configurations to meet customers’ different requirements.
2. High accuracy
Complete advanced processing equipment and technology are introduced from USA to effectively ensure working accuracy and reduce damage to galvanized layer.
3. Less residues
External installable stiffeners contribute to less grain residues on silo walls.
4. Detachable and movable
With standardized and modularized production, components and parts have a high standardization and good interchangeability, thus can be partially replaced or completely transferred.

Thickness range ----3.0-4.0mm
Main motor power ----60kw, AC motor, motor inside of main machine
Roll station ----20stations (according the final design
Shaft diameter ----¢150mm
Machine roll forming speed---- not less than 18 meters per minute
After 20 roller stations,the profile is finished.It consists of DC motor,reducer motor,driven gearbox and rollers.Lathee Bed and drive box adopts welded structure and stress treatment; Gear takes 45 steel hard tooth surface.
The roller uses the combinated structure, the speed difference and the forming resistance are small, the steel plate surface will be less wear; and also guaranteed the precision shape of the working piece with no scratch .The material of the roller is the GCr15 forging, after whole quenching then by numerical control processing, degree of hardness can reach HRC58-62; Has the characteristic with high strength, hardness, precision and long service life etc.
Driven type:it takes gearbox driven
