We offer These Duplex Steel S31803 Pipe Fittings as per DIN, ISO, JIS or ANSI Standard.
Corrosion resistance: Duplex steel S31803 pipe fittings exhibit excellent corrosion resistance, especially in the presence of chloride ions such as seawater and brine solutions. This resistance makes them suitable for offshore oil and gas applications, the chemical industry and the marine environment.
Strength: Duplex stainless steel has higher strength than austenitic stainless steel, providing thinner walls in piping systems without compromising structural integrity. This can lead to cost savings in manufacturing and construction.
High-Temperature Resistance: Duplex steel S31803 has superior mechanical strength, making it suitable for high-temperature resistance applications.
Excellent weldability: Duplex steel S31803 exhibits excellent weldability, making it easy to manufacture and install. This property is useful in complex piping systems where welding is required.
High toughness: Duplex stainless steels combine high strength and toughness, making them resistant to stress corrosion cracking and fatigue failure, especially under harsh operating conditions.
Cost: While duplex stainless steel may cost more initially compared to conventional stainless steel, its long life and reduced maintenance often result in cost savings during the life of the pipeline
Duplex Steel S31803 Pipe Fittings applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Oil and Gas Industry: Duplex steel S31803 pipe fittings are widely used in the oil and gas industry for applications such as offshore drilling platforms, subsea pipelines and finishing equipment. Their corrosion resistance and high strength make them ideal for harsh environments.
Chemical Applications: Double-end steel S31803 pipe is preferred in chemical plants where corrosive materials are used because of its resistance to acids, alkalis and other chemicals.
Desalination plants: Two steel pipe inserts are commonly used to treat seawater for fresh water. The corrosion resistance of duplex steel is essential in such high-salt environments.
Pulp and Paper Industry: Corrosive chemicals and high temperatures are controlled in the pulp and paper industry. This project uses duplex steel pipe fittings to resist corrosion, erosion and pressure corrosion cracking.
Marine Applications: Duplex steel S31803 pipe fittings are used in shipbuilding, offshore platforms and other marine structures due to their corrosion resistance in the marine environment
Water Treatment Systems: Duplex steel pipe fittings are used in water treatment systems where corrosion resistance, high pressure and temperature fluctuations are required
Material Grade: Ensure that the fittings are made of duplex steel grade S31803, providing good corrosion resistance, high strength, and weldability.
Size and thickness: Choose materials that match the thickness and thickness of your piping system. Accurately measure the outside diameter (OD) and wall thickness to ensure alignment.
Pressure and Temperature Check: Check the fittings’ pressure and temperature to ensure they can withstand your system’s operating conditions without failure.
End connections: Consider the type of end connections necessary for your application, such as threaded, socket welded, or butt weld fittings. Choose fittings with the right end connections for easy installation and to match your piping layout.
Corrosion Resistance: Duplex steel S31803 offers better corrosion resistance than standard stainless steel. Ensure that fittings have undergone appropriate corrosion resistance testing and meet the requirements of your application environment.
Certifications and Standards: Look for fittings that conform to relevant industry standards and certifications, such as ASTM, ASME, ANSI, and ISO. These certifications ensure the quality and reliability of the inputs.
