Hot Rolled Tube

High quality of surface properties. The inner and outer surface of the steel tube will not have visible cracks, folds, rolled folds, parting layers and scarring. These defects will be completely cleared, and the removal depth will not exceed the negative deviation of the nominal wall thickness, and the actual wall thickness at the clearing place will not be less than the minimum allowed by the wall thickness. The label of steel tube. Each steel pipe will be marked, each steel tube with a label, the label and label content will include: brand, furnace number, batch number, specification. Material certification Material certification issued acc. to EN10243-3.1, including: Batch No., Grade, Size, Heat No., Length, weight, test method, process, reduction radio, Chemical compostion.

1. Flexible delivery time Production plan can be adjusted according to Customer requirement. Set the safety stock. 2. Precise dimension control Wall thickness tolerance of hot rolled can be limited to +/-5%. 3. Fine structure Based on various furnaces (on-line and off-line normalizing and annealing furnaces, quenching and tempering lines), the steel tube structure can be very fine and uniformed. 4. QT properties Quenching furnace temp difference ≤±3°C. Tempering furnace temp difference ≤±2°C. Hardness deviations on tube full length, internal and external, and circumferentially ≤3HRC.
