High Corrosion Resistance Duplex 2205 Knitted Mesh Pad Demister

High Corrosion Resistance Duplex 2205 Knitted Mesh Pad Demister

1. Duplex 2205 Knitted Mesh Pad Demister Specification in this case:

2. Duplex 2205 Knitted Mesh Pad Demister Material Features,

Duplex stainless steel 2205 alloy is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance.

The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel, which makes the designer reduce the weight when designing the product, and makes this alloy have more price advantage than 316, 317l. This alloy is particularly suitable for temperatures in the range of - 50°F / + 600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially for welded structures.

3. Duplex 2205 Knitted Mesh Pad Demister Application Area,

·Pressure vessel, high pressure storage tank, high pressure pipeline, heat exchanger (chemical processing industry).

·Oil and gas pipeline, heat exchanger pipe fittings.

·Sewage treatment system.

·Pulp and paper industry classifiers, bleaching equipment, storage and processing systems.

·Rotary shaft, press roll, blade, impeller, etc. in high strength and corrosion resistant environment.

·Cargo box of ship or truck

·Food processing equipment

4. Duplex 2205 Knitted Mesh Pad Demister Material Comparison,

Difference between duplex 2205 stainless steel plate and Austenitic 304 stainless steel plate

1) The yield strength of austenitic stainless steel is more than twice as high as that of ordinary austenitic stainless steel

Enough plastic toughness. The wall thickness of the tank or pressure vessel made of duplex stainless steel is 30-50% less than that of austenite, which is helpful to reduce the cost.

2) Even duplex stainless steel with the lowest alloy content has a higher ability of stress corrosion cracking resistance than austenitic stainless steel, especially in chloride containing environment. Stress corrosion is an outstanding problem difficult to solve for normal austenitic stainless steel.

3) The corrosion resistance of 2205 duplex stainless steel, which is widely used in many media, is better than that of 316L austenitic stainless steel, while super duplex stainless steel has very high corrosion resistance. In some media, such as acetic acid, formic acid, etc., it can even replace high alloy austenitic stainless steel and even corrosion resistant alloy.

4) Compared with austenitic stainless steel with the same alloy content, it has better wear resistance and fatigue corrosion resistance than austenitic stainless steel.

5) Compared with austenitic stainless steel, the coefficient of linear expansion is lower, close to carbon steel, suitable for connection with carbon steel, which has important engineering significance, such as production of composite plates or linings.

6) No matter in the condition of dynamic or static load, it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages and practical application value for structural members to deal with sudden accidents such as collision, explosion, etc.

5. Duplex 2205 Knitted Mesh Pad Demister Typical Usages:

• Steam boiler
• Cooling tower
• Distillation column
• Absorption column
• Oil mist elimination
• Gas and air scrubber
• Vacuum and drying tower
• Effluent gas treatment in sulphuric acid factories
