Insert Flanges

Process Piping

      Bestweld manufactures stainless steel and higher nickel alloy Insert Flanges. These are the original flanges that first became popular in the mid 1950’s. They have been successfully used in a variety of industries, including plastics companies, distilleries, pharmaceuticals and paper companies. Bestweld’s flanges can be used for almost all “150#” and “300#” process piping applications.
     They are sometimes referred to as a T/D (taper design), roll-on, SIFCO or Speedline. The major benefit of these types of flanges is the ability to align the bolting holes with rotating flanges. There is no need for bolt hole orientation during installation and rework is practically eliminated.


Insert Flange vs Standard lap-joint and Stub-end flange

     Although similar in concept to the standard lap-joint and stub -end flange, Bestweld’s Flanges are superior in their service. Despite a slightly increased acquisition cost, contractors will see savings in the installation costs and fabrication process.


Cost Savings & Types

     Bestweld’s 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 piece must be made to the same material as the pipe.
     Bestweld offers a variety of styles of Insert Flanges for process piping such as expansion type, slip-on and socket-weld.
