One of the key factors to keep in mind when purchasing pipe flanges is the material choice. These materials include stainless steel, nickel alloys, and plastics. Stainless steel is the most common material for oil rigs and piping systems.
Slip on flange is a type of industrial flange that slides over the end of piping and is then welded in place.
Plate flanges are most used in fuel and water pipelines, where two flange plates are bolted together with a gasket in between them.
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, valves, and pressure vessel openings.
Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore.
Lap Joint Flange does not have a raised face, they are used in conjunction with a “Lap Joint Stub End”.
A weld neck flange is a type of industrial flange designed to transfer stresses to the pipe to reduce high-stress concentrations.
Threaded flanges can be connected to pipes without welding. It can be equipped with a tapered thread (screw) in the flange hole.
An Orifice Flange is used in combination with orifice meters to measure the flow rate of oil, gas, and other liquids.
A spectacle blind is a pressure-retaining plate with one solid end and one open end connected with a web or the bar.
