Product Advantages
-
Anti-rust
No any corrosion after 120 hours' salt spray test
-
Galvanized
Cold galvanized(electrogalvanizing) in bright pipe
-
Color
White, yellow and colorful
-
Bending
No zinc coating drops when bending
-
Pressure sheet
Professional high pressure hydraulic tubing
Cold drawn / cold rolled: High dimensional accuracy, excellent internal and external wall finish
Eddy current testing: Each steel pipe is tested by eddy current flaw detection to ensure product quality
Anaerobic bright heat treatment (NBK): When the seamless steel pipe is annealed, vacuum is applied and ammonia-decomposed nitrogen and hydrogen are injected for protection heating, heat preservation and cooling. It maintains the original rolling accuracy and smoothness of the steel pipe, and has excellent mechanical properties and metallographic structure.
Surface treatment (galvanized): We use environmentally-friendly electro-galvanized technology to form a uniform, dense, and well-combined galvanized layer (over 12μm) on the surface of seamless steel pipes, making it extremely resistant to corrosion and rust.
