With the development of API5L-B pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially the advantages of welded pipe in the range of large-diameter group spacing are more obvious. In 2004, the output of API5L-B (L245) seamless line pipe was about 400,000 tons. The steel grade includes X42-70, normalized ABS grade E hull steel plate, and the varieties include onshore line pipe and subsea line pipe.
Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of normalized ABS grade E hull steel plate circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and normalized ABS grade E hull steel plate management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.
EN10149 S355NC steel plate/sheet,EN10149 S355NC steel plate/sheet, under EN standard, we can regard S355NC steel plate/sheet as normalized ABS grade E hull steel plate high strength steels for cold-forming, normalised steel. EN10149 S355NC is mainly used as high strength steels for cold-forming,normalised steels.The EN10149 S355NC steel grade offers excellent bending,flanging cold
Phosphorus is a very harmful element in normalized ABS grade E hull steel plate steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of normalized ABS grade E hull steel plate steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
Our company will accept the product quality objection registration record, pass it to the normalized ABS grade E hull steel plate production unit and relevant departments, and timely coordinate the supervision of product normalized ABS grade E hull steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
