SS 304L Slip-On Flanges - Easy Alignment & Welding

The SS 304L Slip-On Flange (often abbreviated as SO Flange) is a popular and cost-effective type of pipe component primarily used in lower-pressure, non-critical applications. It is characterized by an internal bore slightly larger than the outside diameter of the pipe, allowing the pipe to be "slipped" into the flange before welding. This ease of alignment and installation significantly reduces fabrication time. The flange is secured by performing fillet welds both inside and outside the flange ring.

Zeron Fasteners specializes in manufacturing and supplying durable SS 304L Slip-On Flanges that comply with ASME B16.5 standards, providing reliable joint solutions for utility services, cooling water systems, and general industrial piping.
