The connection on Slip on Flange is done with two fillet welds, one on the outside and the other on the inside of the flange.

After sliding the flange on the pipe, the distance inside the flange between the end of pipe and the flange face should be: Wall thickness of pipe + 3 mm (1/64 inch). This space is necessary to prevent damage to flange face during the welding process.

All Domestic Steel Pipe Slip on Flanges are made with material forged and machined in USA.

A105 - The standard forged carbon steel piping components for ambient and high temperature / pressure systems

SS304 - A common standard for stainless steel due to its malleability, high corrosive resistance weld-ability  

SS316 - A molybdenum stainless steel that provides excellent tensile, creep and stress-rupture strengths at elevated temperatures
