Slip-on flanges Pressure Vessel Flange series
Pressure Vessel Flange series
Pressure vessels are common in petrochemical, power, and light industries. Types include flat welding, long-neck butt-welding and forged tube sheets and baffle plates.
Slip-on flanges
It is a type of flange where the steel pipe or fittings extend into the flange and are connected to equipment or pipelines through fillet welds.
INTRO
The Slip-On Flange is designed to accommodate lower pressure and temperature applications, featuring a central bore that matches the outside diameter of the pipe. This allows for easy pipe insertion and secure fillet welding on both the interior and exterior sides.
The absence of a weld bevel offers flexibility in adjusting pipe length relative to the flange's position.
Available in large sizes, Slip-On Flanges are ideal for connecting big-bore piping to storage tank nozzles. Typically forged with a hub, they can also be fabricated without one in a ring style for applications with limited space.

Slip-on flanges, connects pipes and fittings to equipment through fillet welds. Its low neck height increases stiffness and load capacity. Unlike butt-weld flanges, it requires more welding and rods and can’t handle high temperature, pressure, repeated bending, or temperature changes. However, it is popular for its easy on-site installation, which skips weld bead grinding.
