Are there any requirements for the pipeline design at the ammonia vaporization station?
Thread Content
Possible problems that come to mind include: 1. Ammonia pipelines must not pass through firewalls； 2. Ammonia pipelines should be electrically grounded ； 3. Butt-welded flanges are used for ammonia pipelines ； (Public pressure is PN25; is a welded flange absolutely necessary?) A flat welding flange with a neck would work too, right? ) 4. Fully threaded studs should be used for ammonia pipelines, along with Type II hex nuts. 5. There are requirements regarding the clear height of pipelines crossing roads (minimum 4.5 meters, usually 5 meters). 6. Special valves designed for ammonia should be used for ammonia pipelines. 7. Are there any requirements regarding the distance between ammonia pipelines and buildings, as well as the distance from other pipelines?
Copper is prohibited as a pipe material, and galvanized materials are also not allowed.
Generally, it is a butt-welded male-and-female sealed flange

Are there any requirements regarding the distance between ammonia pipelines and buildings, as well as the distance from other pipelines? As far as I know, there are no requirements.
