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: Small-diameter pipes can also be loosely packed in plywood boxes instead of bundled in bags for specific needs or handling requirements.
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.
