DIN1630 Black Phosphated Steel Pipe is a black phosphated steel pipe produced in accordance with the German standard DIN1630. This kind of steel pipe has been specially treated, and a black phosphating film is formed on the surface, which has good corrosion resistance and wear resistance. This type of tube is attracting attention due to its excellent mechanical properties and corrosion resistance.
DIN 1630 Black Phosphated Steel Pipe: Performance Features
1. Enhanced Mechanical Strength
The pipe exhibits high tensile strength and structural hardness, ensuring reliable performance under high-pressure and elevated-temperature operating conditions.
2. Superior Corrosion & Rust Resistance
A uniform black phosphate coating provides exceptional resistance to corrosion and oxidation, significantly extending the service life of the pipe in challenging environments.
3. Precision Manufacturing Capability
Manufactured to strict dimensional standards, the pipe is available in high-precision specifications to meet diverse application requirements with consistent accuracy.
4. Optimized Surface Properties
Wear Resistance: The hardened phosphate layer reduces abrasive wear during operation
Improved Lubricity: The coating lowers the coefficient of friction, enhancing operational efficiency
Aesthetic Finish: Delivers a uniform matte-black appearance for both visual appeal and functional performance
5. Long-Term Reliability
Engineered for durability and consistent performance, the pipe maintains structural integrity under prolonged use in demanding industrial conditions.
