Polyurethane Bend Limiter Guideline
As a key protection device, polyurethane bending limiter is widely used in the bending parts of various pipes, cables and hoses to effectively prevent the damage caused by excessive bending and extend the service life. However, proper use is just as important as maintaining a polyurethane bend restrictor.
Correct Installation and Positioning
• Accurate measurement: Before installation, be sure to accurately measure the diameter and bending radius of the pipe or cable, and select the matching polyurethane bending limiter type to ensure the best protection.
• Positioning mark: Mark the installation position to ensure that the bend restrictor is aligned with the bending center of the pipeline or cable, avoiding local stress concentration caused by deviation and affect the protection effect.
• Moderate fastening: When using a special fixing part to fix the bend limiter, the fastening force should be moderate, too tight may lead to polyurethane deformation, too loose may lose the fixing effect
Environmental Adaptability Consideration
• Temperature range: Although polyurethane materials have good temperature adaptability, long-term exposure to extreme high or low temperature environments may still affect their performance. Before use, please confirm that the operating temperature range of the limiter is consistent with the use environment.
• Chemical compatibility: Exposure to certain chemicals may cause degradation of polyurethane materials. When used in chemical factories or corrosive gas environments, the compatibility of the material with the environment must be confirmed in advance.
Regular Inspection and Maintenance
• Visual inspection: Regular visual inspection of the bending limiter for signs of cracks, wear or deformation, and timely replacement of damaged parts.
• Fastener inspection: Check whether the fixing screws or fasteners are loose during each maintenance to ensure that all connected parts remain stable.
• Cleaning and maintenance: Clean the surface of the limiter with a mild cleaner and a soft cloth. Avoid using aggressive solvents to prevent damage to the polyurethane material.
Special Application Precautions
• Dynamic application: If the bend limiter is used in dynamic environments with frequent bending or vibration, special polyurethane materials with higher toughness and fatigue resistance should be selected.
• High pressure applications: For pressurized pipes, choose an enhanced polyurethane bend limiter to ensure effective protection from pipe damage under high pressure.
• High pressure applications: For pressurized pipes, choosing an enhanced polyurethane bend limiter to ensure effective protection from pipe damage under high pressure.
The correct use and maintenance of polyurethane bend limiter can not only extend its service life, but also affect the safe and stable operation of the whole system.
