How is external anti-corrosion done for liquid ammonia pipelines?
Thread Content
Dear teachers, I would like to ask how you handle the external anti-corrosion treatment for liquid ammonia pipelines – what primers and topcoats do you use? The temperature of liquid ammonia is -10 to 40 degrees, with a pressure of 2.0 Mpa. Another issue is that the pipes connected to the liquid ammonia storage tank need to have a certain degree of flexibility. Does this flexibility requirement apply to both the gas-phase pipes and the liquid-phase pipes? How should this flexibility be determined? I chose metal hoses, but the owner said they tend to bulge and are prone to bursting, so they refused to allow their use. Is there a more suitable option? Thank you.
Use pipes in the form of expansion joints; this also causes disturbances
