PHI and Pipe Flanging Machines 

For decades, PHI has been a leading producer of pipe end-finishing machines. We have machines that can handle any sized task and produce a variety of different pipe or tube ends. We offer end-finishing machines that can execute flaring, double flaring, beading, squaring, deburring or flanging. PHI's end-finishing machines use various techniques to increase or decrease the diameter of a pipe or metal tube end.

What Is Pipe Flanging?

Pipe-flanging machines create specific end shapes that allow the joining of pipe sections without the need for expensive welded flanges. Imagine the end of a pipe -- it's simple and cylindrical. By adding a prefabricated slip flange (think of the bottom of an Abe Lincoln stovepipe hat) to two different pipe sections, pipes can be joined together without the threat of leaks.

Pipe-flanging machines use a metal shaping process known as cold forming. With cold forming, metal tubes or pipes are shaped using increased pressure (as opposed to heat). Making use of a hydraulic press, pipe-flanging machines feature a hammering motion that shapes the end of a pipe into a flange.

M343 and M369 Pipe-Flanging Machines

Both the M343 and the M369 are capable of flanging the ends of very large tubes or pipes. Steel pipes with large diameters (three to six inches) can be flanged to a precise degree. These machines were developed to produce pipe ends that can withstand extremely high-pressure applications. Sectors like the petrochemical industry require large diameter pipes that can withstand high-pressure flowage. Preventing leaks is extremely important in these critical, high-pressure systems, and PHI's line of pipe-flanging machines have the ability to creating seamless, secure connections.
