After 14 years, the Olympic flame is shining in China again. The wonderful Beijing Olympic Games has been full of the Chinese style in the near future. The gold medal winning scene of Chinese athletes is boiling with blood. In this Olympic event, the style of stainless steel can not be concealed!
Stainless steel "ice ribbon", shining green winter Olympics
The national speed skating hall, known as the "ice ribbon", is the first single carbon dioxide direct cooling ice rink in China and the largest in the world. The venue adopts the largest all ice design in Asia, with an ice surface area of 12000 square meters, and uses carbon dioxide transcritical direct refrigeration to make ice. The total length of stainless steel refrigeration tubes in the whole ice rink is 120 kilometers, which requires very high quality of stainless steel pipes.
There are more than 100 tons of super long seamless stainless steel ice making pipes with a total length of more than 120 kilometers in the whole Winter Olympic venues. According to the requirements of the construction of the national speed skating hall, there are strict tolerance dimensions for stainless steel ice making pipes. The outer diameters of the two specifications of pipe coils are 20mm and 18mm respectively, and the wall thickness should be accurate to 2mm. The length requirement of stainless steel ice making pipe has become the biggest difficulty in the manufacturing process.
Temporary Building: Stainless Steel Frame
How can tens of thousands of temporary buildings resist freezing and keep warm during the Winter Olympics.
Temporary facilities play an important role in the Winter Olympic Games. According to preliminary statistics, there are more than 14000 temporary stands in the three competition areas, with more than 38000 square meters of temporary houses and more than 2600 square meters of temporary toilets. This time, according to the performance requirements of recyclability, environmental protection and cold resistance, the project team selected stainless steel materials to build the frame of the temporary building.
Torch: high temperature resistant stainless steel
The Olympic torch with double ribbon spiral design is the most eye-catching because of its meaningful and beautiful appearance. The fire plate of the kindling platform is made of high-strength,high-temperature resistant stainless steel, and the snowflake pattern hole of the Beijing Winter Olympic Games is cut by large-scale three-dimensional laser. The surface is sprayed with high-temperature resistant Chinese Red high-temperature paint.
