Anti‑Corrosion CuNi Alloy GB/T 2040 High‑Finned U Tube for Marine Heat Exchangers

Product Description

This high‑finned U tube is made of premium copper‑nickel (CuNi) alloy, strictly conforming to GB/T 2040 standard. It features excellent anti‑corrosion, high heat transfer efficiency and stable structure. Specially designed for marine heat exchangers, it performs reliably in salt spray, seawater and harsh marine environments.

Key Parameters

Material: CuNi Alloy; Standard: GB/T 2040; Type: High‑Finned U Tube; Structure: U‑shaped; Surface: High fin structure; Features: Anti‑corrosion, high heat dissipation, seawater resistant.

Application

Widely used in marine heat exchangers, ship cooling systems, offshore equipment, marine air conditioning, seawater cooling units and other marine cooling and heat exchange equipment.

Product Advantages

CuNi alloy provides outstanding seawater and salt‑fog corrosion resistance; strictly complies with GB/T 2040 standard with stable quality; high fin structure greatly improves heat exchange efficiency; U‑shaped design reduces thermal stress and ensures stable operation; ideal for long‑term use in marine cooling systems.

Product Functions

Efficiently realizes heat exchange and cooling in marine systems; resists marine corrosion to extend service life; U‑shaped structure enhances adaptability to temperature changes; high fins increase heat dissipation area and improve equipment efficiency.

User Manual

Check appearance, fins and tube body before installation; clean the internal passage; install according to marine heat exchanger standards; fix properly to avoid vibration; conduct pressure and leakage test after installation.

Precautions

Avoid collision or damage to fins during transport and installation; do not use under overpressure or overtemperature; keep away from strong corrosive chemicals; store in dry, ventilated environment; professional installation is recommended.
