ASTM B861 Grade 2 UNS R50400 Titanium Alloy Seamless Pipe For Seawater Condenser

ASTM B861 Grade 2 UNS R50400 Titanium Alloy Seamless Pipe

ASTM B861 Grade 2 titanium alloy seamless pipe is made of industrial pure titanium, which combines excellent corrosion resistance, medium strength and good ductility. Its seamless structure is achieved by extrusion or rolling process, without the risk of weld defects, and is suitable for high pressure and harsh environments.

This material has excellent resistance to seawater, chlorides, various acids and alkalis, and is low in density (high strength to weight ratio), non-magnetic and biocompatible.

Typical applications include chemical pipelines, offshore platform systems, seawater desalination equipment and heat exchangers. It is the preferred material for corrosive conditions requiring long life and high reliability, but attention should be paid to the high cost and galvanic corrosion protection when connected with other metals.

Application

Chemical and petrochemical

Process pipelines, reactors, and heat exchanger pipelines for transporting highly corrosive media (such as chloride ions, acidic solutions, and organic acids).
Replace stainless steel in high-temperature and high-chlorine environments where pitting/stress corrosion is prone to occur, significantly extending the life of the equipment.

Marine engineering and ships

Seawater cooling system pipelines, submarine oil and gas pipelines, and drilling platform high-pressure manifolds.
Resist seawater corrosion and biological attachment, reduce maintenance costs, and are suitable for occasions with long service cycles.

Energy and environmental protection

Evaporator tubes and brine heater pipes in seawater desalination devices
Flue gas desulfurization (FGD) system spray pipes, chimney linings

High-end industrial systems

Aviation hydraulic pipelines, aerospace fuel pipelines
Pharmaceutical/bioengineering clean pipelines
