ASTM B165 Monel 400 nickel-copper alloy cold-finished seamless pipe description

GNEE ASTM B165 Monel 400 nickel-copper alloy cold-finished seamless pipe
ASTM B165 Monel 400 cold-worked seamless pipe is a high-strength nickel-copper alloy tube that offers strong corrosion resistance in seawater, steam, and alkaline solutions, but is susceptible to attack by nitric acid and ammonia. Key attributes include excellent low- and high-temperature mechanical properties, cold work-hardening strength, good weldability, and suitability for marine and chemical processing applications.
ASTM B165 Specification
Material: This standard applies to cold-finished seamless pipe made from UNS N04400 nickel-copper alloy.
Testing: This specification requires certain tests, including tensile testing, hydrostatic testing, and nondestructive electrical testing.
Condition: Pipe is supplied in the annealed or stress-relieved condition.

Packing of ASTM B165 Monel 400 cold-finished seamless pipe
ASTM B165 Monel 400 Nickel-Copper Alloy Cold-Worked Seamless Pipe Packaging
Standard Packaging Methods:
Steel Strapping:
Pipe with an outer diameter of 3 inches or less is typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping.
Wooden Cases/Crates:
Pipe is typically packaged in wooden cases or crates for protection during transportation, especially long or large diameter pipe.
Seaworthy Export Packaging:
Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipe during transportation.
Typo-Proof Packaging:
Export crates are designed to prevent rain, seawater, and other external water from penetrating during transportation.
