Heavy-Duty Flanged Rubber Expansion Bellows Product Description Where rigid pipes fail, our Industrial Rubber Expansion Bellows step in. Designed as a flexible, high-density safeguard for high-stress fluid networks, this component neutralizes the intense kinetic energy and thermal elongation that threaten industrial infrastructure. By cushioning the system against relentless pump vibrations, it safeguards sensitive instrumentation and prevents costly flange failures. Available in both single and twin-sphere geometries, it combines robust chemical/thermal resistance with the installation flexibility of rotating flanges—delivering engineered longevity to modern processing plants. Performance characteristics 1. Flexibility: Accommodates axial, lateral, and angular movements. Product Specification

Yes, it is specifically designed to handle lateral, angular, and axial offsets. However, it is important to ensure the misalignment does not exceed the maximum rated limits of the bellows to prevent premature wear on the rubber walls. Q2: What is the maximum pressure rating for this flanged connector? Standard units typically handle PN10 or PN16 (1.0 to 1.6 MPa), but the exact burst pressure depends on the reinforcement layers. For high-pressure environments, we provide specialized high-tensile models with multi-strand steel wire integration. Q3: Is it possible to install this bellows in a vertical pipeline? Absolutely. It can be installed both horizontally and vertically. For vertical installations, ensure the piping is properly supported above and below the joint so that the bellows itself does not bear the total weight of the fluid column. Q4: How does the temperature of the medium affect the rubber's lifespan? Higher temperatures naturally accelerate the aging of elastomers. While our EPDM units can withstand up to 115°C, continuous operation at peak temperature may reduce flexibility over time. We recommend choosing a material grade that exceeds your average operating temperature by at least 20%. Q5: Why does the flange rotate freely on the rubber bellows? This is a "Floating Flange" design. It is intentional to allow for easy alignment with the bolt holes of the fixed pipeline flanges, significantly reducing installation time and preventing the rubber from twisting during the tightening process. |
