Slip On Flange Manufacturer

Products Photos Catalog Slip Flange Photos Catalog

Slip on flanges, also called SO flanges, are a popular type of pipe flange designed to accept pipe into the bore/center of the flange for welding around both the Outer Diameter (OD) of the pipe and on the interior side of the connection.

Design & Installation Principle

The inner diameter of a slip-on flange is slightly larger than the outer diameter of the pipe, allowing the pipe to slip easily into position.

After alignment, fillet welds are applied on both sides to secure the connection.

This simple installation method reduces fabrication time and overall installation cost, making slip-on flanges a popular choice for large-scale projects.
