Introduction
ISO-K HV Double Clamps (Cold Steel, Zinc Plated) are essential fastening components used in ISO-K high-vacuum flange systems. These clamps are designed to securely connect ISO-K flanges and ensure a stable, leak-tight assembly in vacuum pipelines and chambers. ISO-K clamp systems are widely used in high-vacuum environments such as thin film deposition equipment, semiconductor manufacturing tools, analytical instruments, and industrial vacuum systems.
Double clamps provide strong mechanical compression between two mating flanges and the centering ring, enabling reliable sealing while allowing quick assembly and disassembly. Their robust design makes them suitable for vacuum systems that require both mechanical strength and ease of maintenance.
Detailed Description
ISO-K HV Double Clamps are manufactured from high-strength cold-formed steel, which provides excellent structural durability and mechanical stability. The clamps are typically finished with a zinc-plated surface coating, which enhances corrosion resistance and protects the steel from environmental degradation.
The double clamp design includes two clamping arms connected by a tightening mechanism, allowing the clamp to apply uniform pressure across the flange connection. When installed together with a centering ring and O-ring, the clamp holds the two ISO-K flanges tightly in place, ensuring proper sealing within the vacuum system.
ISO-K flange systems are commonly used in high-vacuum (HV) environments, typically operating in the pressure range from rough vacuum down to approximately 10⁻⁸ mbar. The clamp system enables fast installation and removal of vacuum components without the need for complex bolting arrangements.
These clamps are engineered to maintain stable flange alignment while accommodating the mechanical loads associated with vacuum pumping and thermal expansion. Their robust construction ensures long service life even under repeated assembly cycles.
ISO-K HV Double Clamps are available in multiple sizes to match standard ISO-K flange diameters, including ISO-K63, ISO-K100, ISO-K160, ISO-K200, and ISO-K250 systems. The clamps are designed to work in combination with other ISO vacuum components such as centering rings, O-rings, and vacuum tubing.
