Why are urea tubing colors used for identification?
Urea tubing often uses blue as its identification color, and this choice is not arbitrary. Blue has high visibility in industrial environments, quickly distinguishing urea tubing from other pipes. At the same time, blue also symbolizes cleanliness and environmental protection, echoing the environmentally friendly characteristics of urea solution. Using a uniform color helps avoid operational errors and improves safety.
Correct Installation Method for Urea Tubing
Check for sealing: Before installation, ensure the pipe is free of cracks and the sealing rings at the joints are intact.
Avoid bending: Keep the pipe naturally extended; excessive bending will affect solution flow.
Securely secure: Use special clips to secure the tubing, preventing it from detaching due to vehicle movement.
Keep away from heat sources: The installation location should be at least 15 cm away from high-temperature engine components.
Daily Use and Maintenance Points
Urea tubing needs regular inspection, especially in winter when antifreeze precautions are necessary. Use a urea solution of appropriate concentration to avoid crystallization and blockage. Clean with water only; do not use strong acid or alkali cleaners. Replace any tubing that is aged or damaged promptly; do not continue use to avoid leaks.
