Since the Beijing Winter Olympics speed skating competition started, Olympic athletes from various countries have galloped on the ice of the “Ice Ribbon” of China’s National Speed Skating Stadium.
In April 2020, TGJT Stainless Steel Tube Technology Corporation successfully won the bid for the stainless steel refrigeration tube project in the ice-making system project of China’s speed skating venues.
The stainless steel pipe is the main pipe of the stainless steel refrigeration pipe of the entire ice rink, with a total length of about 12 kilometers and a weight of 135 tons. The only new ice competition venue “Ice Ribbon” in this Beijing Winter Olympics is the world’s first Winter Olympics speed skating venue using carbon dioxide transcritical direct cooling ice-making technology. As the “aorta” of the 120-kilometer stainless steel refrigeration pipe in the entire ice rink, the new technology brings new requirements for the product. The first problem to be overcome is that the standard of the pipe is higher than before, and it needs to have more corrosion resistance. , Low temperature resistance, high pressure resistance and so on.
The seamless steel pipe has high requirements on the dimensional accuracy of the steel pipe. If there is a slight deviation, the temperature uniformity of each point cannot be guaranteed.
