Answer regarding the thickness of blast discs
Thread Content
In the fixed-bed batch gasifier process, the operating pressure of the gasifier is 28 MPa. Aluminum plates with a thickness of 1.2 mm have been used throughout the air supply pipes at the bottom of the furnace, which have a diameter of DN700. Now, according to regulatory requirements, rupture discs that comply with relevant design standards are needed. After obtaining the necessary parameters, a batch of ordinary flat-type rupture discs made of 304 material was purchased, with layers of material having thicknesses of 1 mm and 0.5 mm used together. In the absence of any calculations regarding the appropriate thickness for such rupture discs, I would like to ask the experts here: Is the thickness of these rupture discs too great, and will they still be able to ensure safe venting?
Using 304 material blast discs with 1mm and 0.5mm overlaps may be too thick, and may not rupture at the intended pressure. The appropriate thickness of the rupture disc must be determined based on the specific process, pressure level, and design requirements for the rupture disc, in order to ensure reliable discharge at the set pressure and thus guarantee safety. It is recommended to consult professional pressure vessel designers or rupture disc manufacturers to obtain accurate calculation bases and parameters. .
