Product Features:    

A steel pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.

Steel Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminum, brass, bronze, plastic etc. But the most used material is forged carbon steel that include machined surfaces.In addition, flanges, like fittings and pipes, for specific purposes sometimes internally equipped with layers of materials of a completely different quality as the flanges themselves, which are "lined flanges". The material of a flange, is basically set during the choice of the pipe, in most cases, a flange is of the same material as the pipe.

All steel pipe flanges, sold at Trupply fall under the ASME and ASTM standards, unless otherwise indicated. ASME B16.5 describes dimensions, dimensional tolerances etc. and ASTM the different material qualities.

All domestic steel pipe flanges are made by material forged and machined in USA.

Material:                                

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
