ANSI 150 Class Pressure Rating Flexible Pipe Connector: Heavy-Duty Reinforced Bellows Coupler for High-Stress Piping
The American Standard Workhorse for High-Stress Piping Applications.
The ANSI 150 Class Pressure Rating Flexible Pipe Connector is a heavy-duty, engineered bellows coupler built to meet the rigorous demands of industrial piping systems designed to ASME/ANSI B16.5 Class 150 standards. High-stress piping networks—such as those found in power generation, petrochemical processing, HVAC, and industrial fluid transfer—frequently suffer from extreme thermal expansion, structural vibration, and mechanical misalignment.
This heavy-duty flexible connector features a multi-layered, reinforced elastomeric matrix vulcanized with high-tenacity synthetic fiber cord plies, providing exceptional pressure retention and dynamic fatigue resistance. Outfitted with precision-drilled ANSI Class 150 carbon steel or stainless steel backing flanges, it serves as a robust, flexible bridge that isolates pump vibration, relieves pipe wall stress, and maintains zero-leakage security under continuous 150 Class working pressure profiles.
Performance characteristics
Full ANSI Class 150 Compliance: Engineered and tested to integrate seamlessly into ASME/ANSI B16.5 Class 150 piping systems, handling working pressures up to 225 PSI (1.55 MPa) depending on operating temperature.
Heavy-Duty Multi-Ply Reinforcement: Built with embedded layers of high-tensile fabric cord and internal steel wire rings to prevent ballooning, structural deformation, and pressure surges in high-stress lines.
Superior Vibration & Acoustic Attenuation: The elastomeric bellows matrix absorbs solid-borne mechanical vibration and acoustic noise generated by high-output pumps, compressors, and chillers.
High-Capacity Movement Relief: Multi-directional flexibility smoothly compensates for simultaneous axial compression, axial extension, lateral shearing, and angular misalignments caused by equipment settling or thermal growth.
Durable Corrosion-Resistant Shell: Formulated with weather-, ozone-, and abrasion-resistant outer cover compounds, ensuring long service life in both indoor equipment rooms and harsh outdoor exposure.

FAQ
An ANSI Class 150 rating corresponds to a nominal working pressure of 150 to 225 PSI (approx. 10 to 15.5 bar) for ambient temperature service, matching the pressure-temperature ratings of standard ASME B16.5 Class 150 pipe flanges.
In high-stress piping networks, rigid connections transfer equipment vibration and thermal growth directly into pipe anchors, pump nozzles, and valve bodies, leading to fatigue cracks and leaks. This flexible connector acts as a stress-relief buffer, absorbing those dynamic mechanical loads before they can damage critical machinery.
Yes. The attached backing flanges feature standard ANSI Class 150 bolt circle dimensions, hole diameters, and hole counts, making them directly compatible with standard US ANSI B16.5 mating flanges for fast, bolt-on installation.
Control units (limit rods) are strongly recommended when installing this connector on unanchored piping lines or near pumps operating near the upper limits of the 150 Class pressure rating. The tie rods restrict over-extension and compression, preventing the bellows from exceeding its design limits during sudden pressure surges.
Yes. Depending on your process fluid (e.g., raw water, oils, chemicals, or slurries), the inner tube can be customized with specific elastomeric linings like EPDM, NBR (Nitrile), Neoprene, or a PTFE liner for aggressive chemical service.
