Production Range Square & Rectangular Hollow Profiles
External Diameter: 21.3 - 339.7 mm
Length: 4m to 14m
Full Body Heat Treatment
21.3 mm ≤ Outside Diameter ≤ 339,7 mm: Stress Relieving Annealing
21.3 mm ≤ Outside Diameter ≤ 339,7 mm: Normalizing
Stress relieving and normalizing (bright annealing) are carried out offline with atmosphere controlled ''rolled hearth furnace'' between 550 - 700 °C (Stress relieving) and 880-950 °C (normalizing) on full pipe body. By means of full body annealing; micro structure and hardness differences between main material and weld seam are removed and products toughness, grain structure, bending and mechanical properties are improved. After the annealing, high surface quality and bright surface are obtained.
