Triad Bellows specializes in the design and fabrication of customized expansion joints engineered to meet the specific performance and dimensional requirements of your piping systems. These joints are built to absorb movements such as axial compression, lateral offset, and angular rotation, helping to protect piping and equipment from the damaging effects of thermal expansion, vibration, and system pressure changes. Every expansion joint is designed to meet or exceed the standards set forth by the Expansion Joint Manufacturers Association (EJMA), ensuring optimal performance and long-term reliability. Triad offers a variety of configurations—including single, universal, and in-line pressure balanced expansion joints—all of which can be custom built to suit exact pressure ratings, temperature limits, and end connections. Whether your application is in power generation, chemical processing, HVAC, or industrial manufacturing, Triad Bellows delivers tailored solutions that integrate seamlessly into your systems while maintaining the highest standards of safety and quality.

Triad Bellows manufactures fully customized metal bellows that serve as the core flexible component in expansion joints and other dynamic systems. These bellows are engineered to absorb axial, lateral, and angular movement while withstanding high pressure and temperature fluctuations. Available in both single-ply and multi-ply constructions, Triad’s custom bellows are produced from high-performance materials such as T-321 stainless steel, offering exceptional corrosion resistance and fatigue life. Diameters range from as small as 2 inches to as large as 110 inches, allowing for integration into everything from compact assemblies to large-scale industrial pipelines. Every bellows unit is carefully designed using EJMA guidelines and backed by precise manufacturing techniques that ensure consistent quality and performance. Whether you require bellows for pressure vessels, exhaust systems, or vibration isolation in piping networks, Triad Bellows provides engineered solutions tailored to your exact specifications, helping you maintain system reliability and reduce downtime.

Triad Bellows offers a range of support services designed to enhance the shipping, tracking, and turnaround experience for their customers. For international orders, ISPM-15 certified export crating is always provided, ensuring that each shipment is securely packaged to protect against damage and meet global shipping standards. When time is critical, Triad Bellows strives to accommodate emergency shipment requests on a first-come, first-served basis. Expedited orders are evaluated based on material availability and production capacity, with fees determined by the level of urgency and overtime required. To keep customers informed every step of the way, Triad Bellows also provides shipment notifications via email, including UPS tracking details and bills of lading for truck shipments. Additional contacts—such as billing departments or end customers—can be added to the distribution list to streamline invoicing and improve communication. These services reflect Triad Bellows’ commitment to responsive, customer-focused support throughout the order process.

Triad Bellows offers a range of specialized engineering and manufacturing services designed to provide flexible, cost-effective solutions for customers with unique or challenging requirements. If original drawings are missing or incomplete, our reverse engineering service allows you to send in a failed expansion joint for full analysis and recreation—complete with a new drawing for your records. For assemblies where the fittings still hold value, our re-building service offers an economical alternative to full replacement. We’ll replace the bellows, clean and re-machine the fittings as needed, and return the unit fully pressure-tested and painted. For more complex applications, our personalized engineered solutions give you direct access to our experienced engineering team, who will help select or design the ideal expansion joint based on your system’s performance requirements. Backing all of this is our in-house custom machining capability, which includes large-diameter machining, custom flange manufacturing, O-ring groove cutting, precision finishing, and weld end fabrication. Whether you’re rebuilding, retrofitting, or designing from scratch, Triad Bellows delivers precision-engineered support tailored to your needs.
