Duplex Stainless Steel Pipes

Duplex stainless steel has a mixed microstructure of austenite and ferrite, the aim is to produce a 50/50 mix. Commercially these alloys may vary in ratio. Duplex stainless steel pipes have twice the strength, when compared to austenitic steels. Duplex steel have better corrosion resistance than austenitic steels.

 

Duplex stainless steel pipes are slowly becoming popular because of their properties. These pipes are light in weight and have high strength. The duplex steel pipes are corrosion resistant and don’t crack under stress. Duplex stainless steel is cost effective choice as they are corrosion resistant and requires less maintenance.

 

Stainless steel manufacturers and stainless steel pipe suppliers provide in-house corrosion protection and monitoring services. These manufacturers and suppliers can be searched easily on internet.

 

Benefits of duplex stainless steel

The idea of duplex is to produce a chemical composition with approximately equal mixture of ferrite and austenite. This balance makes duplex stainless steel pipes advantageous in many ways.

 

The duplex stainless steel has higher strength than most other types available. This property allows the reduction of section thickness. This helps reduce the weight of pipes. Duplex stainless steel pipes are used in construction industry as they are corrosion resistant. They can handle temperature variations and harsh climate.

 

Duplex stainless steel pipes are resistant to chloride stress corrosion cracking. This makes them fit for use in petrochemical industries. The consequences arising from chloride stress corrosion cracking are costly and catastrophic. This makes use of duplex stainless steel pipes a smart choice as it saves both time and money.

 

Industries that use fluids and materials during industrial operation, which corrode the pipes, use duplex stainless steel pipes as it can withstand exposure to highly aggressive chemicals and fluids. 

 

Duplex stainless steel pies can be easily welded. Duplex steel can be welded faster than other materials. Fabricating duplex stainless steel pipes is also easy. This property of duplex stainless steel pipes also proves to be cost effective.

 

The low nickel content makes it more tensile and resistant than those pipes, which have more nickel.

 

Application of duplex stainless steel pipes

Duplex stainless steel pipes can be used in chemical processing industries, as these pipes don’t corrode on exposure to chemicals.

 

These pipes are also used in petrochemical industries as they can handle fluctuation in temperature and various fluids. Duplex stainless steel pipes are used in oil and gas exploration and refinement industries.

 

Duplex stainless steel pipes are used in pulp and paper industries. They are also used in mining industries and nuclear plants.

 

Duplex stainless steel pipes are fit for use in marine and shipping industries, as they do not get damaged by the salty sea water.

 

Duplex stainless steel pipes are widely used in construction industries because of their strength. These pipes don’t corrode easily. This property makes it apt for use in architectural projects.

 

Duplex stainless steel pipes have multiple applications as they have many benefits. Duplex stainless steel pipes have properties like strength and corrosion resistance, which make them cost effective. Duplex steel pipes require very less maintenance. These qualities have made duplex stainless steel pipes popular.
