Constant Tension Hose Clamps

Constant Tension Hose Clamps are advanced fastening solutions specifically engineered to maintain consistent clamping force on hose and fitting connections, even when subjected to temperature fluctuations or changes in hose material properties over time. Unlike standard clamps that can loosen or overtighten due to thermal expansion and contraction or "cold flow" in hose materials, constant tension clamps are designed to dynamically adjust their diameter to maintain a constant sealing pressure.

This crucial feature makes them indispensable in demanding applications, particularly in the automotive, heavy equipment, and industrial sectors, where significant temperature variations are common. By preventing leaks caused by changes in temperature or hose relaxation, Constant Tension Hose Clamps enhance the reliability and safety of fluid transfer systems.

Product Details

These clamps often incorporate a spring mechanism or a specialized band design that allows for controlled expansion and contraction while maintaining a consistent radial force. Available in various materials, including different grades of stainless steel, they offer excellent corrosion resistance and durability for long-term performance in harsh environments.

Features

  • Maintains Constant Clamping Force: Automatically adjusts to changes in hose diameter caused by temperature fluctuations or material creep. 
  • Prevents Leaks: Ensures a consistent seal, significantly reducing the risk of leaks due to thermal cycling or hose set. 
  • Accommodates Thermal Expansion and Contraction: Designed to expand and contract with the hose while maintaining tension. 
  • Ideal for Extreme Temperatures: Performs reliably in applications with significant temperature variations. 
  • Reduces Risk of Overtightening: Prevents potential damage to the hose or fitting that can occur with over-tightening of standard clamps.
  • Durable Construction: Typically made from high-quality stainless steel for excellent corrosion resistance and longevity.
  • Enhanced Reliability: Provides a more dependable connection compared to standard clamps in dynamic temperature environments.

  • Technical Data

  • Material: Commonly Stainless Steel (various grades like 304, 316), with some components potentially made of spring steel or other alloys for the tensioning mechanism. 
  • Design Type: May include a spring-loaded mechanism within a worm gear housing, a specialized spring band, or other proprietary designs that provide radial elasticity.
  • Clamping Diameter Range: Available in numerous sizes to fit a wide array of hose outer diameters. 
  • Band Width: Varies depending on the clamp series and intended application.
  • Operating Temperature Range: Specified by the manufacturer based on the materials used in the clamp's construction.
  • Clamping Force / Tension: Designed to provide a consistent clamping force within the specified operating range.
  • Installation: May require specific tools for proper installation and tensioning, depending on the design.
