Slip On Flange/ SO Flange
A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange. Slip-on flanges are also defined “Hubbed Flanges” and they are easy to recognize due to their slim and compact shape.

A slip-on flange is a type of flange that is slipped onto a pipe and welded in place. It offers simplicity in installation and cost-effectiveness but may not be suitable for high-pressure or high-temperature applications. Proper welding and material selection are important considerations when using slip on flanges to ensure a reliable and durable connection.
Wuxi Changrun manufactures forged flanges and various forgings for various boilers and pressure vessels according to international and national standards (ASME, ASNI, DIN, GB, JB/T, SH, HG, DG, etc.) with various materials (carbon steel, alloy steel including steel used for high-temperature and low-temperature, stainless steel including duplex steel and etc.). The products are widely used in petroleum & chemical industry, electric industry (nuclear power, wind electricity, thermal power), light manufacturing, machinery, metallurgy, ship craft and etc.
The slip-on flange is characterized by its slim profile and slightly larger outside diameter compared to the pipe it is being attached to. The flange is positioned against the pipe and fillet-welded to provide a strong and durable connection. It is commonly used in piping systems where there is a need for frequent disassembly and assembly, such as in temporary or maintenance applications.
Wuxi Changrun uses plastic protective covers to protect the flange sealing surface, and then uses waterproof plywood boxes for packaging. Waterproof wooden box packaging is suitable for sea transportation.
