Only from a company completely dedicated to innovation.
Senior Flexonics sets the standard in supplying reliable and proven metallic, composite and PTFE hoses, flex connectors, metal hose, metal expansion joints and vibration isolation to industries such as Oil & Gas Refinement, Power Generation, and Steel that are forced to deal with high temperatures and complicated pressure piping systems. In addition to our engineered products, we provide Engineering services to compliment your in-house Engineering or complete Engineering and project management as required.
Senior Flexonics’ reputation for excellence is based on its commitment to continuous business improvement and customer service. We strive to continually improve the operation of our business so that we can serve our customers better.
A History of Innovation
In 1902 James Fentress founded what was to become the Senior Flexonics that you now know. From humble beginnings as a single product manufacturer the company grew into an international organization over the next century. It was a time of innovation and achievement in which the company diversified and expanded to become the great organization it is today. Here is a small list of industry “firsts” that were accomplished with our customers:
- First to make stainless steel hose
- First to make stainless steel bellows
- First to make multi-ply stainless steel bellows for high pressure
- First to make high-strength, butt-welded thin wall stainless steel ducting
- First to make deposition-formed, one piece, thin wall duct components such as elbows, tees, manifolds, and transition pieces that replaced casting and half shells welded together
- First to furnish insulated ducting sheathed and sealed
- First to completely design, manufacture and qualification test an entire high temperature aircraft duct system for heating, ventilating, refrigeration, anti-icing and boundary layer control systems
- First supplier to install complete pneumatic duct flow facilities for environmental testing of components and complete aircraft ducting systems

Metal Expansion Joints
All materials expand and contract with thermal change. In the case of piping systems, this dimensional change can produce excessive stresses throughout the piping system and at fixed points such as vessels and rotating equipment, as well as within the piping itself. A practical and cost effective means of achieving piping system flexibility in a compact design is through the application of metal expansion joints. The most efficient piping system is the shortest and most directly routed system and metal expansion joints make this possible. Metal expansion joints provide an excellent solution for isolation of settlement, seismic deflection, mechanical vibration and sound attenuation.
Designing of Bellows:
Metal bellows are manufactured from relatively thin-walled tubing to form a corrugated cylinder. The corrugations, commonly referred to as convolutions, add the structural reinforcement necessary for the thin-wall material to contain system pressure. The bellows designer selects the thickness and convolution geometry to produce a bellows design that approaches, and often exceeds the capacity of the adjoining pipe to contain system pressure at the specified design temperature.
Flexibility of the bellows is achieved through bending of the convolution sidewalls, as well as flexing within their crest and root radii. In most cases, multiple convolutions are required to provide sufficient flexibility to accommodate the expected expansion and contraction of the piping system.
