Import Cupro-Nickel Tube — Buy in Bulk from Supplier in India

Cupro-nickel tubes from Alok Group Of Companies are manufactured from a copper-nickel alloy with a typical composition of 70% copper and 30% nickel, offering high resistance to seawater corrosion and excellent thermal conductivity. These tubes are supplied in standard lengths between 3 and 6 metres, with outer diameters ranging from 6 mm to 150 mm and wall thicknesses from 0.5 mm to 5 mm, as specified in the source. The material is not plated or coated but formed from solid alloy billets to ensure structural integrity under pressure and flow conditions.

The tubes conform to standard ASTM B111 and EN 12449 specifications for seamless and welded cupro-nickel tubing used in marine and industrial environments. The surface finish is mill finish, with no polishing or special treatment applied unless requested. Typical tolerances for diameter are ±0.1 mm and for wall thickness ±10%, consistent with industry norms for commercial-grade tubing. The material is non-magnetic and exhibits low biofouling characteristics, making it suitable for heat exchangers and condenser systems.

These tubes are primarily purchased by shipbuilders, offshore platform engineers, and chemical processing plants that require reliable fluid handling in saline or high-temperature environments. Buyers commonly use them in seawater cooling systems, desalination plants, and HVAC condensers. Packaging is in seaworthy wooden crates, with tubes bundled and secured using steel strapping. Trade terms include FOB Mumbai and CIF global ports. Minimum order quantities are not stated in the source and must be confirmed directly with the supplier.
