Reliable Air Transfer for Spark-Intensive Industrial Environments
PU Anti Spark Tube is engineered for safe and reliable air transfer in industrial environments where sparks, heat, and continuous mechanical movement are present. It is widely used in industrial air hose, pneumatic hose, automation systems, robotic welding lines, and various industrial air supply applications, helping maintain stable air delivery while improving operational safety and overall production efficiency in demanding working conditions.
Dual-Layer Flame-Resistant Structure
The tube features a high-quality polyurethane air hose inner layer combined with a flame-resistant hose synthetic outer jacket. This dual-layer construction effectively protects the air line from welding sparks, radiant heat, and surface wear caused by constant friction and movement. The flame-retardant PU hose is designed to perform consistently in harsh industrial environments where standard PU hose may fail.
UL94 V-0 Flame Retardancy Performance
LANGCHI The specimen is ignited for 10 seconds for the first flame application, and the time required for the flame to extinguish is recorded. A second 10-second ignition is applied immediately, and the extinguishing time is recorded again. When the total afterflame time from both ignitions does not exceed 30 seconds and no flaming drips are observed, the material is classified as UL94 V-0.
Flexibility, Kink Resistance, and Abrasion Protection
The PU Anti Spark Tube demonstrates excellent kink resistance, allowing it to maintain a stable shape during repeated bending, twisting, and continuous movement. Its smooth inner surface supports consistent air flow with minimal pressure loss, while the abrasion-resistant PU hose outer jacket protects the tube surface in dynamic and mobile systems. The non-sticky jacket design allows for easy cutting and convenient removal of the protective layer during installation, routing, and routine maintenance.
Operating Conditions and Material Properties
Designed specifically for air as the working fluid, the tube operates reliably within a temperature range of -20°C to 70°C. With a hardness range of 95A to 98A, the tube achieves an effective balance between mechanical strength and flexibility, supporting long-term continuous operation in automated production line tubing.
Typical Applications
The flame-retardant PU tube is suitable for a wide range of applications, including industrial equipment, robotic systems, welding air hose, and integrated wiring systems. It is especially recommended for environments with frequent spark exposure, offering a safe, durable, and reliable High-performance polyurethane air hose solution for modern automated production lines and industrial pneumatic systems.
