The unique Unisource “Ultralon” expansion joint combines the properties of metal and fluoroplastics into the most advanced, versatile expansion joint on the market today. Ultralon was designed to meet the process piping needs of the high-technology, chemical/petrochemical, power generation, pulp and paper, and other demanding needs.
The Ultralon expansion joint is versatile and will:
Ultralon is a problem solving product in many high temperature applications. Unlike ordinary solid PTFE or elastomeric joints, should up-set conditions exceeding 500 °F occur, Ultralon will maintain its pressure carrying capacity up to 1200°F—long enough for system shut-down and replacement.
The construction of the Ultralon expansion joint utilizes a stainless steel, Inconel, Monel, or Hastelloy bellows in combination with a PTFE or FEP tube or lining formed into the bellows during manufacture. Ultralon expansion joints can offer working temperatures from -300°F to +400°F, and a choice of bellows rated for working pressures of 50, 150, or 300 psi. Gimbal, hinged, dual externally pressurized, and pressure balanced styles are construction options. Flanges are available in carbon steel, stainless steel, or Teflon coated. Ultralon expansion joints can be manufactured in custom overall lengths and in custom movement capabilities.
