It seems there is no pipe of the DN550 specification! Unless tubes made from sheet coil 550 are used, but I’m not sure how to choose the flanges! Hope someone with more experience can give some advice! Pay attention
Reply to 1# luoheng116: For container flanges, JB/T 4701, 4702, or 4703 can be used directly; there are ready-made options available among them. If there is no pressure rating, it must be calculated using software.
Without standards, make it non-standard and calculate the drawings
Agreed. If there’s nothing ready-made, calculate it using software
Selection of pressure vessel flanges is in accordance with JB4700～4707-2000.
Container flanges generally follow the standards set by the Ministry of Chemical Industry, such as HG20592~HG20596
