Duplex S32205 Key performance advantages

S32205 pipes have achieved an excellent balance between strength and corrosion resistance, its high mechanical strength allows the wall thickness to be reduced during design, thereby reducing material consumption and installation costs, good thermal conductivity and low thermal expansion coefficient are better than austenitic stainless steel.

Application of s32205 pipe

Oil and gas: submarine pipelines, downhole tools for acid gas wells.

Chemical equipment: sulfuric acid reactors, phosphoric acid evaporators, pickling equipment.

Nuclear industry: containers and pipelines for nuclear waste treatment systems.

Marine engineering: seawater desalination devices, heat exchangers.

Environmental protection: key components of flue gas desulfurization (FGD) systems.

Alloy 2205 Pipe Manufacturer process

Both hot and cold forming are possible, but it should be noted that its high strength and work hardening tendency may require greater processing force.

1.4462 Duplex 2205 Pipe welding

welding is an important link, and it is recommended to use matching duplex steel welding materials (such as ER2209), strictly control heat input and interlayer temperature, and ensure that the cooling rate after welding is fast enough (water cooling if necessary) to maintain the ideal phase balance and avoid the precipitation of harmful intermetallic phases. It is critical to follow standard welding procedures such as ASME IX.
