How to divide the explosion-proof zones for Class A buried storage tanks
Thread Content
How is the explosion-proof zone for buried storage tanks containing acrylic acid and toluene defined? It seems that GB50058 only covers outdoor above-ground tanks; there seems to be no provisions for buried tanks.
I think we can refer to the drawing of explosion zoning for gasoline underground storage tanks in the specifications for fueling stations.
Hello, it seems we’re in the same industry. Would it be possible to exchange contact information?
I have another question for the experts: if there are flange connections inside the cofferdam, how many meters should be used as the measurement? Fifteen meters?
I didn’t draw it that way; what I drew was the area three meters away from the entire storage tank, plus the space inside the entire cofferdam. The standard used as a reference was the Urban Gas Code.
But there will still be Faraday interfaces inside the cofferdam
1. Every storage tank must have flanges, right? Chengran has surely taken that into account. 2. The explosion regulations state that cofferdams can serve to restrict the explosion zone. That’s what I think.
Refer to GB3836.14; the main considerations include hazard sources, their characteristics, classification, grouping, release levels, and explosion-proof types. It is best to have a design institute carry out area segmentation, as this helps to mitigate risks
