Type of Sub-products

Duplex Steel S31803 Slip On Flanges

Duplex Steel S31803 Slip On Flanges are an essential component in piping systems, offering a cost effective and reliable solution for connecting pipes in industrial applications. Made from Duplex Stainless Steel grade S31803, these flanges combine excellent strength and corrosion resistance, making them suitable for harsh environments like those found in the oil and gas, petrochemical, marine, and chemical industries. The duplex microstructure of austenite and ferrite provides superior resistance to stress corrosion cracking, pitting, and crevice corrosion. Slip on flanges are designed to slide over the pipe and then be welded into place, offering ease of installation and a strong, leak proof seal.

Duplex S31803 Weld Neck Flanges

Duplex S31803 Weld Neck Flanges are crucial components used to connect pipes in high pressure and high stress applications, offering excellent strength and resistance to corrosion. Manufactured from Duplex Stainless Steel grade S31803, these flanges possess a unique microstructure of both austenitic and ferritic phases, providing superior mechanical properties, including enhanced resistance to stress corrosion cracking, pitting, and crevice corrosion. Weld neck flanges are designed with a long, tapered neck that allows for a stronger and more durable welded joint, making them ideal for applications in the oil and gas, chemical, and marine industries, where leak free, high performance connections are critical.

Duplex S31803 Blind Flange

Duplex S31803 Blind Flanges are essential components used to seal the ends of pipelines, providing a secure and reliable closure in various industrial systems. Made from Duplex Stainless Steel grade S31803, these flanges offer superior resistance to corrosion, including pitting, crevice, and stress corrosion cracking, making them ideal for harsh environments such as those found in the chemical, petrochemical, oil and gas, and marine industries. The unique duplex microstructure, which combines both austenitic and ferritic phases, ensures high strength, excellent toughness, and excellent resistance to chloride induced corrosion. Blind flanges are designed to cover the open end of a pipe, enabling easy maintenance and system modifications.

Frequently Asked Questions

What are Duplex Steel S31803 Flanges?

Duplex Steel UNS S31803 Flanges are manufactured using a duplex stainless steel alloy. This alloy provides excellent resistance to corrosion and is particularly resistant to stress corrosion cracking. It also offers greater strength than other austenitic stainless steel, making it perfect for high-pressure uses. These flanges come in blind, slip-on, and weld neck designs to accommodate applications and possess favorable weldability characteristics. ASME 16.5 Duplex Steel UNS S31803 Flanges can be utilized in temperatures ranging from -50°F to 1200°F.

What are the standard specifications for Duplex Steel S31803 Flanges?

Duplex Steel S31803 Flanges are commonly produced to meet global standards for size and strength specifications, such as ASTM A182, ASTM A240, ASTM A276, ASTM A479, and ASME B16.5 or ASME B16.47.

What is the Duplex Steel S31803 Flange used for?

Duplex Steel S31803 Flange is designed for applications that require superior corrosion resistance compared to S31803. S31803 is a duplex stainless steel grade with enhanced resistance against pitting and crevice corrosion. These flanges are widely utilized in environments that contain chloride ions, including seawater applications, desalination plants, and chemical processing plants.
