These pipes are widely used in construction, wastewater management, and general structural applications where high corrosion resistance is essential.
  • ERW (Electric Resistance Welded) Super Duplex Pipes: Produced by welding the seam through electric resistance, ERW Super Duplex pipes are suitable for low to medium-pressure applications, including water and gas transmission and structural support in corrosive environments.
  • LSAW (Longitudinal Submerged Arc Welded) Super Duplex Pipes: Made by welding along the length of the pipe, LSAW Super Duplex pipes are known for their high strength and are ideal for large-diameter pipelines, especially in oil and gas transportation where durability and corrosion resistance are critical.
  • SSAW (Spiral Submerged Arc Welded) Super Duplex Pipes: Manufactured in a spiral welding pattern, SSAW pipes offer flexibility in diameter and length, making them ideal for water transportation, marine environments, and other applications requiring long, flexible pipelines.
  • EFW (Electric Fusion Welded) Super Duplex Pipes: Produced by fusing plates through an electric process, EFW Super Duplex pipes feature a robust structure suitable for high-pressure applications and long-distance pipelines. These pipes are often used in harsh environments where resilience and corrosion resistance are essential.

Industrial Applications of Super Duplex Pipes

Oil & Gas Pipelines

Super Duplex pipes are extensively used in the oil and gas industry due to their excellent corrosion resistance, particularly against chloride-induced stress corrosion cracking. They are ideal for transporting crude oil, natural gas, and refined products in both onshore and offshore environments, where high strength and durability are essential for long-distance pipelines.

Water Treatment & Desalination Plants

With their resistance to pitting and crevice corrosion, Super Duplex pipes are widely used in desalination and water treatment facilities. They are suitable for transporting seawater and other corrosive fluids in applications requiring high reliability and extended service life.

Marine & Offshore Applications

Super Duplex pipes are preferred for marine and offshore environments due to their outstanding resistance to seawater corrosion. They are used in subsea pipelines, risers, and structural applications on offshore oil platforms, ensuring high performance in harsh, saline environments.

Petrochemical & Chemical Processing

Super Duplex pipes are highly valued for conveying corrosive chemicals and gases. Their ability to withstand high temperatures and resist chemical attacks makes them ideal for refinery applications, acid processing, and chemical transport systems.

Power Generation

Super Duplex pipes play a crucial role in power plants, particularly in cooling water systems, steam generators, and heat exchangers. Their ability to resist corrosion and high temperatures ensures reliable performance in nuclear, thermal, and natural gas power facilities, where consistent operation is critical.

Pulp & Paper Industry

In pulp and paper manufacturing, Super Duplex pipes are commonly used to handle bleaching solutions and other corrosive chemicals. Their high corrosion resistance and durability make them well-suited for this industry, which requires materials that can withstand aggressive substances and high pressures.

Affordable Super Duplex Pipe Prices

The price range for Super Duplex pipes typically falls between $2,000 to $5,000 USD per metric ton, depending on factors such as grade, size, and additional processing requirements. Various elements impact the final cost, including:

Grade and Material Composition

Higher grades, like UNS S32750 and UNS S32760, tend to have a higher price due to their enhanced properties, which make them suitable for highly corrosive and high-pressure environments.

Pipe Size and Thickness

Larger diameter and thicker pipes require more material, which can increase the cost. For instance, Schedule 40 Super Duplex pipes may be less expensive than Schedule 80 or Schedule 160 due to differences in thickness and material requirements.

Surface Coating

Additional coatings like 3-Layer Polyethylene (3LPE), Fusion-Bonded Epoxy (FBE), or zinc galvanizing can raise the price due to the extra processing required for corrosion resistance, especially in challenging environments.

Manufacturing Type

Seamless Super Duplex pipes are generally more costly than welded pipes due to the intricate production process, which involves high precision and labor, ensuring strength and durability.
