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.
Application
General Use: These tubes are designed for boilers, heat exchangers, and condensers.
Corrosion Resistance: They resist general corrosion, making them suitable for various corrosive environments.
High-Temperature Service: ASTM B516 tubes can handle high-temperature services, essential in industrial operations like energy production.
Low-Temperature Service: Similarly, they are capable of operating in low-temperature conditions.
Stress Corrosion Cracking Resistance: The materials are particularly resistant to stress corrosion cracking in chloride-bearing environments.
Industrial Applications: Common applications include petrochemical industries, chemical equipment, offshore oil drilling, and gas processing.
Additional Uses: They are also used in seawater equipment, heat exchangers, the pulp and paper industry, and pharmaceuticals.
