Frequently Asked Questions (FAQ)
Q1: What materials are available for ultra-high purity applications?
A: We utilize electrolytically polished 316L stainless steel or Hastelloy materials. These achieve a surface roughness of Ra≤0.4μm, making them ideal for cleanliness-critical industries like semiconductor and bio-pharmaceutical manufacturing.
Q2: How do your bellows perform under high temperature and pressure?
A: Designed with 8-12 reinforced interlayers, our bellows can handle axial loads up to 15MPa and operate reliably in temperatures ranging from -50°C to 300°C, delivering over 2 million fatigue cycles.
Q3: Are these bellows suitable for ultra-high vacuum environments?
A: Yes. Thanks to advanced welding technology and low out-gassing treatment, our bellows maintain absolute sealing at vacuum levels below 10⁻⁶ Pa, satisfying requirements for spacecraft propulsion and synchrotron radiation facilities.
Q4: What range of physical displacement can these bellows compensate for?
A: They offer precision compensation of ±5mm axial, ±2° angular, and ±1.5mm radial displacement to protect systems from misalignment and vibration.
Q5: Can I request customized sizes and specialized alloys?
A: Yes, we provide custom configurations with diameters ranging from 10mm to 500mm. Material options include Titanium, Inconel, and Monel to withstand extreme service environments.
Q6: Do these bellows support high-speed rotational applications?
A: Absolutely. They maintain exceptional dynamic reliability with less than 0.01% torque transmission error even at speeds up to 5000 RPM.
