Issues regarding the new container supports per NB/T47065
Thread Content
According to NB/T47065.1-2018, the three types of bearings 159/377/426 have been removed from the list of allowable bearings; instead, three new specifications, 168/356/406, are now used. So, how should one choose bearings of the 159/377/426 type for steam cylinder applications in the future? ? ?
Just choose directly; they’re basically the same. Think about it, how can one design without this standard?
Do I have to calculate that strength calculation sheet by myself? ? ?
Could such a small device damage the saddle? It’s estimated that anyone can pick it up
Pipes used in the chemical industry come in metric and imperial versions; we **use metric pipes (pipe flanges of series B), while Europe and the United States use imperial pipes (pipe flanges of series A). For example, for ND350 pipes, the outer diameter of imperial pipes is 355.6, whereas that of metric pipes is 377. The standard has changed from metric to imperial units; if your equipment uses metric-sized pipes for the steam drum, you can still use it by selecting according to the standard. Adjust the outer diameter of the pipes and gaskets accordingly.
