EN 10219 S235JRH Welded Pipe
EN 10219 S235JRH Welded Pipe is the specification for cold-formed welded structural hollow section pipe which is made from non-alloy and fine grain steels. Its cold forming method increases the mechanical properties and dimensional accuracy of the sections. It enhances the material properties by reforming it at room temperature which increase the strength and improves its surface finishing. It is been frequently utilized for construction and structural purpose where accurate dimensions and high load-bearing capabilities are essential.
Moreover, it's good welding properties makes easy fabrication and also constructing difficult shape product.
But the greatest concern during welding these grade of material is the growth of cold cracking in the welded area as the thickness increase, the cold cracking occurs. Hence, it is essential to note that this product is applicable for low thickness product.
1.0039 Steel Hollow Section gives good impact resistance and toughness which gives reliability and protection in structural applications. Below given are its applications in various fields.
Construction of Bridge
It is used for constructing building frameworks due to its properties of high strength and good welding properties.
Structural Frame
EN 10219 S235JRH CHS Tube is utilize for structural frame works for buildings and other infrastructural projects. It provides strength and support to the structure which guarantees safety and security to its structure.
Factory Structures
It is utilize for manufacturing of factory building and units of industry. It gives strong framework which are capable for supporting heavy machinery.
Mechanical Engineering Applications
It is appropriate for mechanical engineering which needs strong and well-built structural elements.
