Is it necessary to install a cofferdam around the pump set?
Thread Content
I would like to ask everyone for their input: is it necessary to construct a retaining wall around the pump sets (pumps for Class A liquids) located outside the fire dike in the Class A tank area? Thank you!
No, I’ve never heard of such a statement. For information regarding pump rooms, you can refer to SHT3014-2002, the Design Code for Pump Rooms in Storage and Transportation Systems of Petrochemical Enterprises. I hope this helps you.
Reply to 1# sharonbei: It is necessary. In PVC production, dikes are installed around the vinyl chloride storage areas and pumps to prevent the spread of this highly volatile flammable gas in case of a large-scale leak.
There are no specific regulations in SH3014, but as a personal habit, I always install cofferdams around the pump set when designing.
Thank you all. After discussing it with others, I think it’s better to install a cofferdam around the pump set to prevent leaks and to stop liquid from spreading during maintenance. Thank you
