What are the requirements for chemical processing equipment in marine transportation?
Ensure nitrogen sealing inside (inert gas can also be used), and take measures to prevent salt spray corrosion on the outside.
What should the nitrogen sealing pressure generally be set at?
0.3~0.5 bar is both acceptable
Sea transport: 1. Internal dew point of the equipment; 2. Nitrogen filling at a level of 0.3–0.5; 3. External anti-corrosion coating or salt-resistant layer; 4. Sealed packaging with nitrogen filling and rust-proof paper
Stainless steel equipment and composite panel containers transported by sea need to be protected with nitrogen or an inert gas inside, mainly to prevent chloride ion stress corrosion.
Seal it tightly with plastic wrap on the outside to prevent corrosion by seawater.
Marine transportation: prevent seawater vapor from entering the equipment； Second, it provides rigid support to prevent deformation during transportation. A nitrogen protection pressure of 0.03 MPa is generally sufficient.
