What are Stainless Steel Slip-On Flanges?

Stainless Steel Slip-On Flanges are pipe flanges designed to slide over the end of a pipe before being welded in place. Unlike weld neck flanges, slip-on flanges fit directly over the pipe and are secured using both internal and external fillet welds.

Their simple design allows for easy installation, precise alignment, and reduced fabrication costs. Stainless Steel Slip-On Flanges are commonly selected for low- to moderate-pressure applications where ease of assembly and economical installation are important considerations.

Due to the excellent corrosion resistance of stainless steel, these flanges perform exceptionally well in aggressive environments involving chemicals, moisture, seawater, and high temperatures.
