Product Description: SO Steel Pipe Flanges

Product Name: Steel Slip-On (SO) Flange

SO flanges, also known as slip-on flanges, are a popular type of pipe flange that slide over the end of piping and are then welded in place. They are designed to be slightly larger on the inside than the pipe, and are commonly used for fluids at low pressure or with little risk of leakage. SO flanges are often used in cooling water lines, firefighting water lines, low-pressure compressed air lines, and process lines for substances such as steam, oil, gas, and condensates.

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.
