What are the 2205 duplex steel fittings

bends: For changing the direction of the pipe.
T-jointcap (a poem)cross: For pipe branching.
reducer: For connecting pipes of different diameters.
ball valves,butterfly valvecap (a poem)gate: For controlling fluid flow.
check valves: Prevents reverse fluid flow.

bolt (male component of nut and bolt)cap (a poem)nut (female component of nut and bolt): For joining and securing structural components.
spread litter in a cowshed, pigsty etc: Used to enhance the sealing of the connecting parts.
quick coupling: For quick connection and disconnection of pipes or hoses.
Compression fittings: For non-welded pipe connections.

Selection points

Chemical compatibility: Ensure that the chemical composition of 2205 Duplex Stainless Steel is suitable for specific applications, such as highly chlorinated environments or other corrosive chemicals.
Mechanical compatibilityThe fittings selected need to be able to withstand the operating pressure and temperature of the system. 2205 duplex stainless steel, although corrosion resistant and strong, should be used to ensure that the design and size of the fittings are suitable for their intended use.

Welding material: Use of appropriate welding consumables and techniques, such as ER2209 or E2209 electrodes, to maintain the material's dual-phase structure and optimize weld properties.
processing technology: When machining 2205 duplex stainless steel, proper cutting and forming techniques need to be used to avoid introducing unnecessary stresses or damaging the microstructure of the material.
design standard: Adherence to international and regional standards, such as ASTM, ASME or EN standards, which define material properties, dimensions and testing requirements.
stress analysis: Stress analysis of the load-bearing structure ensures that 2205 duplex stainless steel fittings will not fail under the expected loads.

2205 Stainless Steel Advantages

Excellent corrosion resistance

Due to its high chromium and molybdenum content, 2205 duplex steel has much higher corrosion resistance than standard austenitic stainless steels such as 304 and 316. It performs particularly well in chloride-containing and seawater environments.

high strength

The yield strength of 2205 duplex steel is about 250MPa, which is twice as high as ordinary austenitic stainless steel, so it can be designed to reduce wall thickness and weight, thus reducing costs.

Good welding properties

2205 duplex steel has good welding properties and does not require preheating or post heat treatment. However, in order to maintain its excellent corrosion resistance and mechanical properties, it should be properly heat treated after welding.

Good impact resistance

The duplex structure provides higher strength and toughness. The ferrite phase provides good impact resistance, while the austenite phase provides higher ductility and toughness.2205 Duplex steel maintains good impact resistance at low temperatures.

Installation and maintenance

correct installation: Install in accordance with the manufacturer's instruction manual, ensuring that all connections are correct and tight and that all seals are intact.
maintenance: Develop and implement a regular inspection and maintenance program to promptly identify and resolve potential problems such as wear and tear, corrosion, or damage.

By considering these key points, it is possible to ensure that 2205 duplex stainless steel fittings provide optimum performance and maximum service life in a variety of applications. Proper selection and maintenance will not only enhance system reliability, but also reduce long-term maintenance costs.

Application Areas

Duplex Stainless Steel is widely used in several applications due to its excellent mechanical properties and corrosion resistance. The following are some of the major applications of Duplex Stainless Steel:
