Q1: What working pressure does an "ANSI 150 Class Pressure Rating" specify for this connector?
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.
Q2: What is the main benefit of using a heavy-duty reinforced bellows coupler in high-stress piping?
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.
Q3: Are the flanges compatible with standard US pipe layouts?
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.
Q4: Are control units (tie rods) required for installing this ANSI 150 flexible connector?
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.
Q5: Can this flexible pipe connector be customized with different inner liner materials?
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.
