Insert Flanges

Insert Flanges for Process Piping

Bestweld manufactures stainless steel and higher nickel alloy insert flanges. These are the original insert flanges that first became popular in the mid 1950’s. They have been used successfully in a variety of industries, from plastics companies to distilleries to pharmaceuticals to paper companies. Insert flanges can be used for almost all 150# and 300# process piping applications.

Insert Flanges are sometimes referred to as a T/D (taper design), roll-on, SIFCO or Speedline insert flange. The major benefit of these types of flanges is the ability to align the bolting holes with the rotating flanges. There is no need for bolt hole orientation during installation and much rework is eliminated.

Bestweld Insert Flanges are similar in concept to the standard lap-joint and stub -end flange, but are far superior in their service.

Although insert flanges may cost slightly more than standard flanges, the real cost benefit comes in the fabrication process.

The time saved to fabricate Bestweld Insert Flanges will create a considerable savings to the user at installation.

Also, Bestweld Insert Flanges can help you save money when expensive high nickel alloy pipe is being installed i.e. C-276 and Alloy 20. With an insert flange, only the inner insert piece must be made to the same material as the pipe. The flange can then be made out of less expensive carbon or stainless steel.

Bestweld offers a variety of styles in insert flanges for process piping such as expansion type, slip-on and socket-weld.
