Product Advantages
-
No oxide layer
No oxide layer on both sides of tube
-
Surface
High precision, smooth surface
-
No crack
No crack during flaring and flattening
-
Anti-rust
Anti-rust on inside and outside
-
Cold bending
Cold bending without deformation
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.
Cleaning: We use high-pressure cleaning equipment and ultrasonic cleaning equipment to clean steel pipes. The inner and outer walls are coated with anti-rust oil, and both ends are sealed to prevent dust.
