Superior Erosion & Abrasion Resistance Performance Security High PREN Value

Product Name: Super Duplex Stainless Steel Pipe

Product Specification
SDSS pipes are manufactured to the highest international standards, such as ASTM A790 or A928. They are defined by a typical chemical composition that includes high levels of Chromium, Nickel, Molybdenum, and Nitrogen, resulting in a PREN (Pitting Resistance Equivalent Number) exceeding 40. This composition is meticulously controlled to ensure the optimal 50/50 phase balance, providing the perfect synergy between the strength of ferrite and the toughness of austenite.

Key Product Parameters

Product Applications
Super Duplex pipes are deployed in the world's most demanding industrial sectors.

1. Oil & Gas Offshore/Subsea: Seawater injection lines, process piping, risers, umbilicals.

2. Chemical & Petrochemical Processing: Reactors, heat exchangers, piping for acidic and chloride-containing media.

3. Desalination & Marine: High-pressure reverse osmosis membranes, seawater cooling systems, brine heaters.

4. Pollution Control: Flue Gas Desulphurization (FGD) scrubber systems.

5. General Industry: High-pressure, high-temperature, and high-wear applications.

Product Advantages
This material provides significant operational and economic benefits over conventional stainless steels and nickel alloys.

1. Superior Lifetime Cost Efficiency: The combination of extreme longevity and reduced maintenance delivers the lowest total cost of ownership despite a higher initial investment.

2. Design & Weight Savings: Double the strength allows for thinner walls and lighter structures, reducing material costs and supporting easier installation.

3. Uncompromising Safety & Reliability: Its proven integrity in critical applications mitigates the risk of catastrophic failure, protecting personnel, assets, and the environment.

4. Sustainable Solution: Extended service life reduces the need for replacements, minimizing the environmental footprint associated with manufacturing and logistics.

Product Functions
The core performance characteristics of SDSS pipes enable them to perform under extreme conditions.

1. Withstand Extreme Corrosion: Functions reliably in environments saturated with chlorides, acids, and other aggressive corrodents where standard stainless steels would fail.

2. Handle High Mechanical Stress: Maintains structural integrity under high internal pressure, external loads, and in high-vibration applications due to its high strength and fatigue resistance.

3. Resist Erosion & Abrasion: Protects against material loss and degradation in high-velocity flows and systems containing sand or other particulates.

4. Operate Across Temperatures: Performs effectively across a wide range of temperatures, from cryogenic to moderately elevated levels.
