my country's mechanical seal gasket sealing technology:

After years of development in my country, gasket sealing technology can basically meet the needs of pressure vessels. For example, the manufacture of a urea synthesis tower with a diameter of 2800mm; the construction of large-scale thermal power plants and nuclear power plants in the southern GRN-T series of mechanical seals; the replacement of some imported products by domestic gaskets all show that my country's gasket technology has reached a certain level. A lot of work has also been done in the research of sealing mechanism and new sealing structure. However, due to the limitation of the level of industrialization, the basic theoretical research work started late, so the sealing design parameters (m, y values) and methods in the current GB150~98 'steel pressure vessel' and related standards in China are all selected from the United States 'ASME Code'. In view of the differences between domestic and foreign gasket products and the application of new static seal design methods, the organization will test the sealing parameter values u200bu200b(G, a, Gb) of domestic gaskets to improve my country’s current various gasket standards (including dimensions, materials, manufacturing , Test, Acceptance, Selection>, according to the research progress of static seal design and static seal test results, it is an urgent task for sealing technicians to formulate my country's new static seal design method based on reliability and leakage rate. 　　462.html,
