Products - Insert Flanges for Single Piping

(click here to go to our Product Page for Jacketed Piping Insert Flanges)

These are the original insert flanges that first became popular in the mid 1930's.  They have been used successfully in a variety of industries, from plastics companies to distilleries to paper companies.  Insert flanges can be used for almost all steel piping applications.  These are sometimes referred to as a T/D, roll-on, Bestweld, or Speedline insert flange.  The major benefit of these types of flanges is the ability to align the bolting holes with the rotating flange.  They are similar in concept to the standard lap-joint and stub -end flange, but are far superior in their quality.  Although insert flanges may cost slightly more than standard flanges initially, the real cost benefit comes in the fabrication process.  The time saved to fabricate American Insert Flange (AIF) flanges will create a considerable savings to the user over the long term process. 

Also, AIF insert flanges can help you save money when expensive pipe made out of specialty steel alloys is being used for the pipe. (such as C-276 and Alloy 20)  With an insert flange, only the insert piece must be made to the same material of the pipe.  The flange can then be made out of less expensive carbon or stainless steel.  AIF also offers a variety of styles in our insert flanges for single piping, such as socket-weld and a grooved inside diameter.  If you see a style or weight class not listed below, please email us at sales@americaninsertflange.com for a custom quotation.  Please check out are FAQs section for additional information on insert flanges.

(ASME CONFORMING mean that the flange thickness is engineered via AIF calculations performed by our engineer to fully comply with all pressure temperature/pressure vessel ratings for ASME B16.5.  CONVENTIONAL or standard flange thicknesses means that these insert flanges use the dimension for whatever a standard flange would be.  CONVENTIONAL insert flanges have been used the longest in the industry, however, ASME CONFORMING are more popular today due to ASME code being a growing expectation in piping systems.)
