tank fittings and accessory orientation
tank fittings and accessory orientation
(OP)
Hi. I just need to know what standards or codes I can used as a reference for my storage tanks. I'm doing a layout for my 1500cu.mtr and 750 cu.mtr chemical storage tanks and I need to know what are the standard fittings & pipeline connections as per tank, as well as their locations/orientations (what degrees or distances between them). My tanks will be fixed roof and cone down bottom. Hope you can help me out here. Thank you

However many tanks are just made to no specific code.
Connections - Up to you. There are normally restrictions and practical issues in putting them too close together, but too close is probably equivalent to 1D of the largest nozzle. At 1500 and 750 m3 you shouldn't be short of space.
I've seen nozzles all in one quadrant, I've seen them spaced out all over the place. you need to put your tank down and then work out where your incoming / outgoing pipework is and place the nozzles accordingly.
Always add a few spares.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Carefully consider both the number and locations of your manways based on your process, painting and maintenance requirements for the particular fluids you are storing.
Repeatedly, I have dealt with clients that want to add shell manways based on expected cleaning and painting requirements.
Personally, I do not believe that it is safe to clean or coat tank internals of your recommended size without one or two roof vent hatches or manways.
A couple of spare inlet/outlet nozzles at the bottom of the shell are a low cost insurance policy
Many clients also desire a slightly more expensive flush cleanout at the bottom of the shell.
