Tubes are manufactured from mild steel strips slitted from Hot Rolled Low Carbon Steel coils. The strip passes through a series of drive forming and fin rolls and takes the required circular shape and is welded continuously by passage of an electric current of high frequency.
Advantages
Due to its excellent workability, scrap loss is minimal.
Due to its uniformity and concentricity, lighter walls can be specified, reducing the allowance for stock removal.
Standards
ASTM A513 Type 1
Hot Rolled Electric-Resistance Welded (ERW) Carbon Steel Mechanical Tubing
