S275 Welded Hot-rolled Carbon Steel Round Weld Tubes

Introducing S275 Welded Welded Pipe for Construction

S275 welded hot-rolled carbon steel round welded pipe is a type of pipe widely used in building structures under the European standard system. It perfectly combines the mechanical properties of the material, the precision of manufacturing, and the economic cost, making it an indispensable component of modern steel structure buildings.S275 welded hot-rolled carbon steel round welded pipe is a backbone material for modern building steel structures. With its standardized strength, excellent processing performance, precise geometric dimensions, and significant economic benefits, it provides architects and engineers with a reliable option for achieving lightweight, large-span, and diverse building designs, making it an ideal solution balancing safety and efficiency.

Hot Rolling Process Introduction for S275 Round Carbon Steel Welded Pipes

Hot rolling is a key technology for rolling steel above its recrystallization temperature. Its core process flow is as follows:
1,Heating: The continuously cast slab is fed into a heating furnace and uniformly heated to approximately 1200-1300℃, an austenitizing temperature, giving it good plastic deformation capabilities.
2,Rough Rolling: After descaling with high-pressure water, the red-hot slab is rolled in multiple passes through a reversible rolling mill, compressing the slab thickness from several hundred millimeters to 30-50 millimeters.
3,Finish Rolling: The intermediate slab is further thinned to the target thickness using a 6-7 stand continuous finish rolling mill, and the plate is cooled at a strictly controlled rate using a laminar flow cooling system.
4,Coiling: When the strip cools to approximately 550-600℃, it is coiled into a coil by a coiler, ultimately forming a hot-rolled product with a dense structure and excellent mechanical properties.
