Features and Benefits
-
High Quality and Quick Delivery:
We pride ourselves on delivering high-quality precision carbon steel tubes in a short timeframe. Our consistent quality assurance process covers everything from manufacturing to final inspection, ensuring that each product meets the highest standards.
-
Nondestructive Testing:
Every material undergoes thorough nondestructive testing via eddy current inspection to identify and eliminate any potentially harmful defects. This ensures the integrity and reliability of our products.
-
Bright Heat Treatment:
Our bright annealing furnace method provides a scaleless finish on both the inner and outer surfaces of the tubes. This not only enhances corrosion resistance but also promotes improved mechanical properties.
-
Custom Wrapping for Small Quantities:
If needed, we can wrap products in plastic bags to maximize stock efficiency and prevent rust, particularly when only a small quantity is required.
