SINCE 1955

George B. Marzolf, Sr. invented the MARZOLF® two-piece back-up flange in 1955 and was granted a patent in 1959. As the story goes, Mr. Marzolf was touring a paper mill in Wisconsin, watching as a large pipe was being hoisted into position. One man was maneuvering the pipe into place with his hands, when the straps suddenly slipped, launching the solid backing ring down the length of the pipe crushing the man’s hand. As Mr. Marzolf reflected upon the incident he thought to himself. “There must be a way to install those rings after the pipe is securely in place.” And the MARZOLF® two-piece flange was born. Plant safety was the genesis of the MARZOLF® flange; maintenance efficiency is the by-product, and they both hold true today. Since then, the fluid process industry has changed and The MARZOLF® Company has evolved right along with it.
