Brief: In this video, we provide a dynamic demonstration of the Single Sphere Flexible Rubber Bellows, showing how it effectively handles high-temperature piping systems. You'll see a detailed walkthrough of its construction, material layers, and performance under various conditions, including axial and radial displacement tests. Learn how this high-elasticity, airtight joint accommodates thermal expansion and resists harsh media in industrial applications.
Related Product Features:
  • Constructed with high-elasticity rubber for excellent flexibility and airtightness in piping systems.
  • Features multiple rubber layer options including IIR, CR, EPDM, NR, and NBR for varied media resistance.
  • Reinforced with polyester cord fabric and bead rings to withstand working pressures up to 1.6 MPa.
  • Designed to operate in a wide temperature range from -20°C to +115°C, with special conditions up to 250°C.
  • Suitable for conveying diverse media such as air, water, seawater, hot water, oil, and acid-base solutions.
  • Accommodates axial displacement (extension and compression) and radial displacement to absorb pipe movements.
  • Available in flange materials including Q235, 304, and 316L for corrosion resistance and durability.
  • Provides reliable performance under vacuum conditions, with ratings of 53.3 kPa for smaller sizes and 44.9 kPa for larger ones.
Faqs:
  • What temperature range can the Single Sphere Flexible Rubber Bellows withstand?
    The bellows are designed to operate in temperatures from -20°C to +115°C under standard conditions. For special applications, they can handle temperatures as low as -30°C and as high as 250°C, making them suitable for high-temperature piping systems.
  • Which media are compatible with this flexible rubber expansion joint?
    This joint is compatible with a wide range of media, including air, compressed air, water, seawater, hot water, oil, and various acid-base solutions. The inner and outer rubber layers are available in materials like IIR, CR, EPDM, NR, and NBR to match specific media resistance needs.
  • What are the key displacement capabilities of this rubber bellows?
    The bellows can accommodate axial displacement (both extension and compression), radial displacement, and angular deflection. Specific values vary by size; for example, a DN50×32 model allows 15 mm extension, 18 mm compression, 45 mm radial displacement, and a 35° deflecting angle.
