The general working flow of big size tube mill line is shown as follows: Decoiling - Shear and butt welding - Accumulator - Roll forming - High-frequency ERW - Removing burrs - Cooling - Sizing - Flying saw
You can easily find the existence of big-size tubes as piling pipes for bridges. Normally, the big-size tubes can function as piers, roads, buildings, and other structures tubes.
