Anti-Spark PU Pneumatic Tube for Welding Robots: Guide
Welding automation places unusual demands on a pneumatic air line. A tube may need to feed a robot gripper, clamp, positioning cylinder or welding-gun accessory while sparks, hot particles, abrasion and repeated movement are present nearby. Ordinary tubing can still carry compressed air, but its exposed surface may be damaged long before the pneumatic circuit reaches its design life. The HOMIPNEU Double Layer Anti-Spark PU Pneumatic Tube uses a flexible polyurethane inner tube with a flame-retardant protective outer layer. The double-layer structure is intended to reduce damage from welding sparks, hot spatter and metal particles while preserving practical flexibility for industrial air routing. This guide explains where anti-spark PU tubing fits, how to choose a PUH model, how to size the line for airflow, and which hazards still require a separate guard or a different hose. The product is protection-oriented tubing, not a guarantee against direct flame, prolonged molten-metal contact or every welding hazard. What Is Double-Layer Anti-Spark PU Tubing? Double-layer anti-spark PU tubing combines two functions in one pneumatic line. The inner polyurethane tube carries compressed air and allows…
