High Pressure Expansion Joints Furnished to Toyo Engineering

Senior Flexonics Pathway is well known around the world for design and fabrication of high pressure engineered expansion joints. The expansion joints required for applications in the manufacture of certain types of polymer require extreme design pressures. The expansion joints Senior Flexonics Pathway built for polymer manufacturing facilities recently designed and constructed by Toyo Engineering included many safety features that have become standard with Senior Flexonics Pathway.

The expansion joints require reinforcing rings to handle the extreme operating pressures. The Senior Flexonics Pathway reinforcing ring design is a solid stainless steel extrusion that results in a very smooth profile in contact with the bellows. This unique Senior Flexonics Pathway ring design eliminates stress risers that can reduce bellows fatigue. The bellows were all Ply Testable construction, another Senior Flexonics Pathway design standard for critical service expansion joints. The Ply Testable design provides a 100% safety back up system for the bellows element in case the inner ply of the bellows becomes damaged or corroded.

The expansion joints shipped to job sites in West Java, Indonesia and Guangzhou, Peoples Republic of China.
