2. Material Characteristics
Our SMLS (Seamless) ASTM A210 high - pressure tubes are made from high - quality carbon - manganese - silicon steel. The carbon content is precisely controlled within a range that provides an optimal balance between strength and formability. Silicon enhances the steel's strength and improves its resistance to oxidation at elevated temperatures. Manganese contributes to the overall strength and hardenability of the steel, ensuring the tubes can withstand high - pressure environments. The carefully selected alloy composition also gives the tubes good weldability, facilitating fabrication processes when required.
3. Mechanical Properties
- Tensile Strength: These tubes exhibit a minimum tensile strength of 415 MPa. This high tensile strength enables them to endure significant mechanical stress without experiencing deformation or failure, making them suitable for high - pressure applications.
- Yield Strength: With a minimum yield strength of 240 MPa, our ASTM A210 tubes offer excellent resistance to permanent deformation under applied loads. This property is crucial for maintaining the integrity of the tubes during operation.
- Elongation: The elongation percentage is typically not less than 25%. This relatively high elongation value indicates good ductility, allowing the tubes to be bent, flared, or otherwise formed during installation without cracking.
4. Manufacturing Process
The manufacturing of our SMLS ASTM A210 high - pressure tubes follows a highly precise and rigorous process. It starts with the selection of premium - grade steel billets. These billets are then heated to a specific temperature range and pierced using a mandrel to form a hollow shell. Next, the pierced tube is rolled to the desired outer diameter and wall thickness. After the rolling process, the tubes undergo a series of heat treatments, including normalizing and tempering. Normalizing helps to refine the grain structure, improving the mechanical properties of the steel, while tempering relieves internal stress and further enhances toughness. Finally, each tube is thoroughly inspected using non - destructive testing methods such as ultrasonic testing and hydrostatic testing to ensure compliance with ASTM A210 standards.
5. Application Range
- Power Generation: In power plants, especially in boiler systems, our SMLS ASTM A210 high - pressure tubes are extensively used. They can withstand the high - pressure and high - temperature steam conditions, ensuring the efficient and safe operation of the boiler.
- Petroleum and Natural Gas Industry: These tubes are suitable for various applications in the oil and gas sector, such as transporting high - pressure fluids in refineries, pipelines, and well - head equipment. Their high - pressure resistance and durability make them reliable for such demanding environments.
- Industrial Pressure Vessels: For industrial pressure vessels used in chemical processing, food and beverage production, and other industries, ASTM A210 high - pressure tubes are an ideal choice. They can safely contain high - pressure substances and maintain their structural integrity over time.
