Product Description: SO Steel Pipe Flanges

Product Name: Steel Slip-On (SO) Flange

Product Description:

Our Steel Slip-On (SO) Flanges are a reliable and cost-effective solution for your piping systems. These flanges are manufactured from high-quality steel, ensuring robustness and longevity.

Slip-On Flanges are easy to install and remove, making them ideal for lower pressure applications. The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. This double welding process reinforces the strength of the connection, making it sturdier and leak-resistant.

  2. Sizes: Available in a range of sizes to fit different pipe diameters. Custom sizes can also be created upon request.
  3. Standards: Manufactured according to ASME B16.5 and B16.47 standards, guaranteeing quality and compatibility with various pipe fittings.
  4. Ease of Installation: Slides easily over the pipe and secures with welding, providing a robust and reliable connection.
  5. Applications: Ideal for use in lower pressure applications and suitable for industries such as petrochemical, oil & gas, water treatment, and more.
