What Is SS Welded Pipes?

SS welded pipes combine the benefits of seamless construction and the economical production of welded pipes. The term "seamless" refers to the manufacturing process in which the pipe is made from a single piece of metal without any welded joints, offering superior structural integrity. These pipes are especially advantageous for high-pressure applications or environments where even the smallest flaw in the pipe could lead to failure.

The Grade 304 stainless steel used in these pipes is a chromium-nickel alloy known for its excellent resistance to oxidation, corrosion, and high temperatures. This makes it an excellent material for piping in industries like chemical processing, food and beverage, oil and gas, and even marine applications.

Why Choose 13.7 mm Diameter x Sch 10?

  • 13.7 mm Diameter : A smaller diameter, such as 13.7 mm, is ideal for systems that require compact piping. This is commonly used in fluid transport systems where space-saving design is essential, such as in HVAC, automotive, or precision machinery applications. It also offers versatility in various industrial applications.
  • Schedule 10 (Sch 10) : The "schedule" of a pipe refers to the wall thickness and is a critical factor in determining the pipe's pressure handling capacity. Schedule 10 is relatively thin-walled, making it lightweight and more cost-efficient, while still offering adequate pressure resistance for low to medium pressure systems. This makes Sch 10 piping suitable for applications where cost savings are a priority without compromising safety or performance.

Key Features of Grade 304 Stainless SteelWelded Pipes:

  • Corrosion Resistance: Grade 304 is highly resistant to most oxidizing acids, making it ideal for piping systems that may encounter corrosive environments. This property extends the life of the pipes, reducing maintenance and replacement costs.
  • Temperature Tolerance: These pipes can withstand high temperatures, which makes them suitable for both cryogenic (extremely cold) and high-temperature applications without losing their structural integrity.
  • Mechanical Strength: The seamless construction provides greater strength and pressure resistance compared to welded pipes, especially important in applications like chemical transport or gas lines.
  • Ease of Fabrication and Maintenance: : Grade 304 stainless steel is easy to clean and maintain, and can be fabricated to fit various dimensions and shapes depending on the system's requirements.

Common Applications

  • Chemical and Petrochemical Industries:Ideal for transporting corrosive liquids or gases.
  • Food and Beverage Processing: Its non-reactive nature makes it a good fit for transporting consumable products.
  • Marine Applications: Grade 304’s resistance to seawater corrosion extends its usage in maritime industries.
  • Pharmaceutical Equipment:Used in systems where hygiene and resistance to contamination are crucial.

Advantages Over Other Piping Solutions

  • Lower Maintenance Costs: The corrosion resistance of Grade 304 results in fewer repairs and replacements, reducing downtime.
  • Environmentally Friendly: Stainless steel is 100% recyclable, offering a sustainable solution.
  • Aesthetic Appeal: In industries where appearance matters (e.g., architectural piping), stainless steel offers a clean, polished look.
