• Anti-rust – Anti-rust on inside and outside
• Cold bending – Cold bending without deformation

Product Video / Quality & Processing
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): During annealing vacuum protection and ammonia-decomposed nitrogen and hydrogen are injected for protected heating, heat preservation and cooling to maintain rolling accuracy, smoothness, mechanical properties and metallographic structure
Cleaning: High-pressure and ultrasonic cleaning for inner and outer walls; inner and outer walls coated with anti-rust oil and both ends sealed to prevent dust
