I need help with a problem related to pipes
Thread Content
Our company has purchased a sodium silicate mixing machine with an internal pressure of 6 kilograms. We need to install a pressure gauge at the outlet; the area marked in the diagram uses 6-inch cast iron components. We’re not sure whether these components can withstand such pressure. We’ve searched for relevant standards but couldn’t find any appropriate ones. How can we determine the pressure that these pipe fittings can handle? Or which standard provides tables relating to this?
Check the certificate for the elbow; it indicates whether cast iron is required, and generally it isn’t needed.
It should be possible, but a valve should be installed on the pressure gauge’s pressure conduit; replacement of the pressure gauge also needs to be taken into consideration.
Is adding another pair of safety valves below the pressure gauge meant to control whether the pressure gauge opens?

As a precaution, it is best to use elbow welding. A friend upstairs said that a root valve for the pressure gauge is also needed, so that it’s easier to replace the gauge if it gets damaged. :lol
Using cast iron parts should also be fine, but it’s necessary to check the pressure rating of the elbows chosen
See if this standard applies. Judging from the picture, the pressure rating is likely PN10
When installing valves, it is necessary to consider the issue of shutting off the gas supply when replacing the pressure gauge
