Packing
Small Diameter Pipes and Tubes:
End treatment: Beveled or plain ends are capped or plugged with plastic protectors.
Bundling: Smaller diameter pipes and tubes are grouped in bundles.
Protection: Bundles are then covered with seaworthy bags to protect against moisture and damage during transport.
Alternative packaging: For specific needs or handling requirements, small-diameter pipes can also be loosely packed in plywood boxes instead of bundled in bags.
Large Diameter Pipes:
End treatment: Similar to small diameters, beveled or plain ends are likely capped or plugged.
Loose packing: Larger diameter pipes are individually packed and not bundled due to their size and weight.
Protection: Each pipe is covered with a seaworthy bag to protect it against the elements and potential damage during shipping.
Application
Handling caustic soda (sodium hydroxide): Nickel 200 exhibits excellent resistance to caustic soda at various concentrations and temperatures, making it suitable for pipelines, reactors, and other equipment in caustic soda production and handling.
Processing of other alkaline solutions: Used for handling potassium hydroxide and other alkaline solutions.
Production of synthetic fibers: Resists corrosive chemicals used in manufacturing synthetic fibers, such as rayon and nylon.
Equipment for handling food products: Suitable for applications where hygiene and corrosion resistance are critical, such as handling salt, brine, and other food products.
Components in electronic devices: Its high electrical conductivity and corrosion resistance make it suitable for various electronic applications.
Battery components: Used in nickel-cadmium and other battery systems.
Aerospace and rocketry: Components requiring high purity and good thermal conductivity.
Laboratory equipment: Used in laboratory apparatus and instrumentation due to its corrosion resistance and inertness.
Caustic evaporators: Nickel 200 tubes are commonly used in caustic evaporators due to their excellent resistance to concentrated caustic solutions at high temperatures.
Salt production: Pipelines and equipment for handling brine and salt solutions.
Food processing equipment: Tubing for handling milk, juices, and other food products.
