What type of pipe should be used to connect an 800L liquid ammonia cylinder to the vaporizer?

We used steel wire hoses before, but they’re not allowed anymore.
A stainless steel tube will do. However, this matter cannot be handled casually. It is necessary to contact the higher-level equipment management and safety department to handle this, so as to avoid taking responsibility. For reference.
The regulations clearly state that copper or copper alloys cannot be used for ammonia; it should be chlorine instead
Thank you! What type of stainless steel pipe should be used? Straight pipes are difficult to install; could pipes similar to fine coiled tubes be used?
It depends on the requirements for traffic. It would be best to work with the platform on which the storage tank is placed; for example, it’s possible to move it up and down, as well as horizontally, and then lock it in place – this is also an approach that can be considered. Even if thin tubes are used, there is a risk of tube failure due to metal fatigue; it seems better to modify the platform instead, for reference.
The flow requirement is not high – 20-30 m³/h. Can a quick connector be used? If using the platform for movement and screw connections, it’s probably difficult to align them properly
For specific details, you should consult the supervisory department that has requested you to make the corrections; they offer specialized technical consultation services to ensure that the requirements are met. This is provided for reference only.
The flexible hose bar. This expert can find no faults; just add a shut-off valve in between.
