In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the A572 grade 55 high strength steel steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
Ultrasonic flaw detection emits ultrasonic waves to the A572 grade 55 high strength steel steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the A572 grade 55 high strength steel steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous A572 grade 55 high strength steel pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
