Hydroformed Bellows – ASA Flanged (Rotatable)
TFM specializes in the fabrication of ASA flanged formed bellows designed for high voltage (HV) systems. These bellows are constructed using 300 series stainless steel flexible hoses combined with 304L stainless steel ASA flanges. ASA flanges serve as efficient vacuum seals for HV applications, featuring one grooved flange that accommodates an O-ring and a corresponding smooth (flat) mating flange.
Features of Hydroformed Bellows – ASA Flanged (Rotatable)
- Durable Flexibility: Our bellows are designed to endure numerous flexing cycles without cracking, ensuring long-term reliability in demanding environments.
- Leak-Free Design: The seam-welded construction effectively eliminates virtual leaks typically associated with lap-welded seams, providing a dependable seal.
- Versatile Flange Configuration: Each assembly includes one rotatable and one fixed ASA flange, available in various combinations of flat and grooved styles to meet specific application requirements.
- Dynamic Hose Flexibility: Unbraided flexible hoses can extend up to 10% beyond their live length and compress by up to 15%, accommodating movement without compromising performance.
- Protective Braiding: The braided flexible hoses are equipped with a protective sheath that helps shield the convoluted hose from damage, enhancing durability and extending service life.
At TFM, we are committed to delivering high-quality solutions tailored to the unique demands of HV systems, ensuring optimal performance and reliability.
