COPPER NICKLE 90:10 TUBE FERRULE INSERTS

Copper Nickel 90 : 10 Tube Ferrule Inserts

Copper Nickel 90 : 10 Tube Ferrule Inserts are precision-engineered components designed to provide reliable tube-to-tubesheet reinforcement and leak-proof sealing in heat exchangers, condensers, and marine cooling systems. Manufactured from Copper Nickel 90 : 10 alloy (90% Copper, 10% Nickel), these inserts offer excellent resistance to seawater corrosion, biofouling, and erosion in marine and offshore environments.

Designed with accurate dimensions and tight tolerances, Copper Nickel 90 : 10 Tube Ferrule Inserts help prevent tube end deformation, leakage, and vibration-related wear. The alloy provides outstanding resistance to stress corrosion cracking and maintains strength and durability under continuous seawater exposure, making it ideal for marine and desalination applications.
