Do all foam generators have glass baffles inside?
Thread Content
When I opened the foam generator, I found that there was no glass baffle inside. It was broken and it felt like it had never been installed inside. Is there any foam generator that does not require the installation of a glass baffle?
Check the information of the foam generator or consult the manufacturer. The foam generators here will be equipped with flowering glass. This is very simple. You can find a local glass installer to make it. If the glass is not installed, a large amount of oil and gas in the oil tank will penetrate into the foam line.
It seems that the external floating roof does not need to be installed with blasting glass.
Thank you mryu for your advice. I checked and found out that Article 3.6.1, Article 5 of GB50151-2010 "Foam Fire Extinguishing System Design Code" states that "foam generators on external floating roof storage tanks should not be equipped with sealing glass."
