         2. Surface treatment: Bright, galvanized (yellow, white, colorful), phosphated，army green passivation.
Features
  • High Pressure Resistance: Designed to withstand high internal pressure, ideal for hydraulic and pneumatic systems.
  • Precision Manufacturing: The pipe is cold drawn to ensure accurate dimensions and smooth surfaces.
  • Durable Surface Finish: The NBK(normalized, bright) treatment enhances the pipe’s resistance to corrosion and improves its overall mechanical properties.
  • Corrosion Resistance: The bright surface finish reduces the risk of rust and corrosion, enhancing the pipe’s lifespan.
  • Reliability: Made from high-quality E235+Nsteel, ensuring the pipe can handle demanding environments.

 

Surface Finish

  • NBK (Normalized, Bright):
  • The pipe undergoes NBK treatment, which normalizes the steel to relieve internal stresses and gives the pipe a smooth, bright finish. This treatment improves both corrosion resistance and surface quality, which is critical for high-pressure applications.
