Production Standards and Steel Grades

Adhering to rigorous production standards is essential for the quality and reliability of seamless steel tubes. Key standards include:

• ASTM A179
• GB6479 (Grades: 10#, 20#, 16Mn, 15MnV, 12CrMo, 15CrMo, 12Cr2Mo, 12SiMoVNb)

These standards ensure excellent mechanical properties, corrosion resistance, and overall quality, making them suitable for various applications in the heat exchange industry.

Delivery Condition

Seamless steel tubes are available in several delivery conditions, allowing for customization based on application needs:

• Annealed
• Normalized
• Normalized and Tempered

These conditions optimize the mechanical properties of the tubes, ensuring durability and performance.

Inspection and Testing

Quality assurance is fundamental in the production of seamless steel tubes. A comprehensive suite of inspections and tests is conducted, including:

• Chemical Composition Inspection: Ensuring compliance with specified grades.
• Mechanical Properties Tests: Evaluating tensile strength, yield strength, elongation, flaring, flattening, hardness, and impact resistance.
• Surface and Dimension Tests: Confirming the physical characteristics of the tubes.
• Non-Destructive Tests: Checking for internal and external defects without damaging the product.
• Hydrostatic Tests: Validating structural integrity under pressure.

These rigorous testing procedures ensure that every product meets high-quality standards.

Surface Treatment

To enhance durability and performance, a range of surface treatments is offered, including:

• Oil-dip: Providing corrosion resistance and ease of handling.
• Varnish: Offering a protective coating against environmental factors.
• Passivation: Improving corrosion resistance through chemical treatment.
• Phosphating: Enhancing adhesion for paints and coatings.
• Shot Blasting: Achieving a clean and uniform surface finish.

These treatments extend the lifespan of the tubes and maintain optimal performance.
