The Benefits of Using SMO 254 Pipe in Desalination Plants

Using SMO 254 stainless steel piping in desalination plants offers many advantages. It is corrosion-resistant and has a high chromium content, making it ideal for producing potable water in saltwater areas where it is highly saline. Its robust structure also ensures that it can withstand temperatures up to 1000°F, which makes it suitable for hot seawater applications. Additionally, the smooth surface makes SMO 254 pipe easy to clean and maintain, reducing maintenance costs. From an environmental standpoint, its non-toxicity eliminates the possibility of contamination from leaching chemicals or metals when exposed to sea salt air or even brine solutions found in desalination units. Finally, this type of pipe is generally cheaper than other materials like copper because it uses less labour-intensive manufacturing processes while providing superior corrosion resistance and strength levels.

What is SMO 254 Pipe?

SMO 254 is a high alloy austenitic stainless steel pipe manufactured by Sandvik Materials Technology. It offers excellent resistance to corrosion and oxidation, with higher strength than grade 304 stainless steel pipes making it suitable for many challenging applications in industries like chemical processing, offshore oil and gas production, pulp and paper production, etc. This alloy has good formability and weldability properties with adequate toughness even at cryogenic temperatures. Additionally, SMO 254 exhibits greater pitting corrosion resistance over other austenitic stainless steels due to its higher chromium content (22–25 wt%) and Molybdenum addition (6–8 wt%).

Corrosion Resistance

Seawater is highly corrosive, and many materials, including standard steel, are unsuitable for desalination plants due to their susceptibility to corrosion. SMO 254 pipe, however, is resistant to various corrosive media, including seawater, making it an excellent choice for use in desalination plants. SMO 254 pipe also exhibits excellent pitting and crevice corrosion resistance, common in seawater applications.

Long Life Span

Durability is a crucial factor in selecting materials used in desalination plants. SMO 254 pipe offers unparalleled durability, ensuring a long lifespan and reducing the need for frequent maintenance. In addition, SMO 254 pipe is less susceptible to erosion and wear, ensuring that it retains its structural integrity over time.

Environmental Benefits

Desalination plants require significant energy to operate and typically use large quantities of chemicals for water treatment. SMO 254 pipe plays a role in reducing the environmental impact of desalination plants by reducing the frequency of maintenance and replacement, which reduces waste and minimizes the use of energy and chemicals required for plant operation.


While SMO 254 pipe may initially seem more expensive than other materials, it’s long lifespan, and low maintenance requirements make it a cost-effective choice in the long run. The durability of SMO 254 pipe means it is less likely to require replacement, ultimately reducing downtime and operating costs.


SMO 254 pipe is a versatile material that can be easily integrated into various desalination plant designs. It is available in various sizes and configurations, making it an ideal choice for large-scale and smaller-scale desalination projects. Furthermore, SMO 254 pipe can be used with other materials and technologies to create custom solutions to meet specific project requirements.

Chemical Composition of SMO 254 pipe

SMO 254 (Super Austenitic Stainless Steel) pipes are made from Chromium, Nickel, and Molybdenum. Chromium provides corrosion resistance, and Nickel provides good mechanical strength and flexibility. Molybdenum improves the ability of the material to resist localized corrosion such as pitting or crevice attack in chloride environments. Typical chemical compositions for SMO 254 pipes include 17-21% chromium, 6-8% nickel, 1.5-3% molybdenum and 0.03 max sulfur with carbon content lower than .20%.


In summary, SMO 254 pipe offers many benefits for desalination plants, including exceptional corrosion resistance, durability, environmental benefits, cost-effectiveness, and versatility. As the demand for freshwater continues to grow, desalination plants will play an increasingly significant role in meeting this demand. Choosing the right materials, such as SMO 254 pipe, will be critical to ensure these plants’ efficient and sustainable operation.
