Hose Clamp Testing Using Pressure Distribution

Pressure Measurement Validates Hose Clamp Design

Hose clamps must prevent leaks in a variety of demanding circumstances. For example, in cold temperatures, rubber hoses shrink and become brittle. When an engine is started, liquids and high pressures are generated inside the hose before the rubber has expanded. If the hose clamp does not seal well, leaks may result. Therefore a good hose clamp seal is required. With the I-Scan^® pressure measurement system, you can easily instrument a hose and clamp to test various hose thicknesses, designs, materials and how they react under different variables such as temperature.

This information can be used to design the optimal hose clamp and to complement FEA model validation. Sensors are available in different shapes, are reusable, and provide accurate pressure readings. With the help of Tekscan's highly qualified sales and engineering support team, each system may be configured to meet your specific needs.

 Temperature change affects total clamp force and contact area for a screw hose clamp on a nipple. The clamp exhibits very high clamping pressures at room temperature and no leakage path (top left). However, at cold temperature, the clamp does not provide any seal (top right).
