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 against the elements and potential damage during shipping.

Application

Nickel 200/201 (UNS N02200/N02201):
Chemical Processing: Handling caustic alkalis, especially at high temperatures.
Food processing: Equipment for handling food products, particularly those containing salt and brine.
Synthetic fiber production: Resisting corrosive chemicals used in the manufacturing process.
Electronics and electrical components: Due to their high electrical conductivity and resistance to corrosion.

Monel 400 (UNS N04400):
Marine applications: Piping systems, seawater handling equipment, and desalination plants due to their excellent resistance to seawater corrosion.
Chemical processing: Handling hydrofluoric, sulfuric, and other corrosive chemicals.
Oil and gas industry: Components exposed to seawater and sour gas environments.
Power generation: Feedwater heaters and condenser tubing.
