Monel 400 UNS N04400 U Bend Tube ASME SB163 Seamless Nickel Alloy Tube
Monel 400 UNS N04400 Seamless U Bend Tube
YUHONG supplies high-performance Monel 400 U Bend Tubes manufactured in accordance with ASTM B163 and ASME SB163 standards. Produced from UNS N04400 nickel-copper alloy, these seamless tubes provide excellent resistance to seawater corrosion, hydrofluoric acid, alkalis, and high-temperature environments.
Monel 400 U Bend Tubes are widely used in shell and tube heat exchangers, condensers, boilers, power plants, offshore platforms, petrochemical plants, and marine engineering projects. The seamless construction ensures superior mechanical strength, leak-free performance, and long service life under demanding operating conditions.
Each tube undergoes strict quality control procedures, including dimensional inspection, hydrostatic testing, eddy current testing, PMI verification, and mechanical property testing to ensure compliance with international specifications.
