Slip on Flange

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.
Standards & Size Range
Our slip-on flanges are manufactured in accordance with international standards
to ensure compatibility with global piping systems:
ANSI / ASME B16.5 (NPS 1/2” – 24”)
ANSI / ASME B16.47 (Large Diameter Flanges)
AWWA C207 (Waterworks Flanges)
EN 1092-1 / ISO 7005 (European Standards)
Available sizes typically range from DN15 (1/2”) up to DN600 and above,
depending on the applicable standard and project requirements.
