Universal Metal Bellows Expansion Joints are constructed with two metal bellows of equal length separated by a center pipe. This expansion joint design will accept large amounts of lateral offset in multiple planes. The amount of deflection is based on the amount of angulation each bellows can take and the length of the center spool. The designers at Triad Bellows can increase or decrease the lateral deflection capability and cycle life by changing the center pipe length. As with all designs at Triad our universal metal bellows expansion joints are engineered and manufactured in strict accordance with EJMA 10th Edition. Standard universal metal expansion joints do not use tie rods and require the system piping to be properly anchored.

Tie Rod Bellows Pump Connectors are almost always constructed with multi-ply bellows that will stand up to the pump vibration. This style expansion joint is usually very short and has limited movement capability. Triad Bellows manufactures metal bellows pump connectors that are made with domestic materials that meet AIS, Buy America and Buy American requirements.

The Multi-ply metal bellows used in our standard expansion joints are made in 3 standard lengths, 6 live length, 9 live length and 12 live length. Review the performance data and choose the bellows length that is best suited for your exhaust or ducting system. When selecting an expansion joint simply choose the part number that corresponds with your chosen bellows live length. All of the metal bellows and expansion joints are designed and manufactured in accordance with the guidelines latest edition. If you dont see what you need just let us know. As with all Triad Bellows products custom lengths are never a problem. Our design engineering team will gladly assist you with your selection.

T-321 stainless steel exhaust flex hose is an economical solution for a flexible connection between the engine and the exhaust piping. Exhaust flex is most commonly used in noncritical applications, such as stand by generators. Our line of Isoflex exhaust flex hose assemblies are designed to outperform standard flex assemblies over time. The most common failures with standard exhaust flex assemblies occur at the heat-affected zone, due to annealing that is created by the welding process. Isoflex products remove the heat effected zone with spacialized weld techniques. For all critical applications, we recommend the use of our Triad CycleMAX multi-ply bellows to insure that your system will function as you intend. Our engineering staff is ready to assist you in choosing the right product for your specific application.
