Process
Steel making in Converter → Refine → Continuous Casting → Hot Rolling → Uncoiling → Accumulator → Cross Welding → Strip End Shear → Strip Leveling → Edge Milling →Strip UT → Forming → Electric Resistance Welding → Sizing → Air Cooling+ Water Cooling → Online Weld Seam Heat Treatment → Online Weld SEAM UT → Bevelling → Hydrostatic Testing → Weld Seam UT → Pipe UT → Appearance and Dimension Check → Coating → Marking → Length-measuring and weighing → Packing → Transportation
Packing: Plastic plugs in both ends, Hexagonal bundles of max.2,0O0kg with several steel strips, Two tags on each bundle,Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel strips, Plastic caps.
Test Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties(Flattening Test,Bending Test,Hardness Test, lmpact Test),Exterior Size Inspection, Hydrostatic Test,NDTTEST(ET TEST,RT TEST, UT TEST)
