Product Specifications

Commodity Name

Seamless Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes

Process Method

We employ advanced cold-drawn and cold-rolling techniques to create tubes with enhanced dimensional accuracy and surface finish. These methods ensure that our products maintain integrity under high-pressure and high-temperature conditions typical in boiler and heat-exchanger applications.

Surface Finish

Our tubes are available with an annealed surface finish. This process not only improves the mechanical properties but also enhances resistance to corrosion, making them suitable for a variety of operational environments.

Materials Used

Our seamless tubes are manufactured from high-grade materials including:

• TP304
• TP304L
• TP316L
• TP316/316L

These materials are carefully selected for their excellent resistance to oxidation and corrosion while maintaining high strength at elevated temperatures.

Standards

Our manufacturing processes rigorously adhere to the ASTM (ASME) SA/A213/M standards, which dictate the required specifications for seamless austenitic alloy steel tubes. This compliance ensures that our products can withstand rigorous testing and meet the necessary safety and performance benchmarks.

Sizes

Our seamless tubes are available in a variety of dimensions to meet specific customer requirements:

• Outer Diameter (O.D.): Ranges from 1/4" to 48"
• Wall Thickness (W.T.): Options include 10BWG, 12BWG, 14BWG, 16BWG, 18BWG, 20BWG, and 22BWG

Length

The maximum length of our tubes is 12.5 meters, allowing for seamless integration into existing systems without the need for extensive welding.

Delivery Conditions

Our products are delivered in an annealed and pickled condition, ensuring that they are free from surface contaminants and ready for immediate use in critical applications.

Applications

The versatile nature of our seamless tubes makes them suitable for:

• Fluid and Gas Transport: Ideal for carrying various types of fluids and gases in industrial applications.
• Structural Applications: Suitable for use in construction where high strength and durability are required.
• Machining: Can be utilized in manufacturing processes, where precise dimensions and material strength are crucial.

Packing

To ensure protection during transit, each piece is individually wrapped in plastic bags and then packed in seaworthy wooden cases. This method preserves the quality of the tubes from the manufacturing site to the final destination.

Minimum Order Quantity

We accept a minimum order quantity of 0.5 metric tons, allowing flexibility for both small and large-scale projects.

Delivery Time

We pride ourselves on our efficient supply chain management. Our standard delivery time is 30 days from the date of order confirmation.

Industry Standards and Compliance

The ASTM (American Society for Testing and Materials) and ASME (American Society of Mechanical Engineers) standards are essential in ensuring the quality and reliability of materials used in high-pressure and high-temperature applications. Specific requirements in the ASTM A213 specification include:

1. Material Composition: Detailed analyses of the chemical composition to assess the resistivity against corrosion and thermal environments.

2. Mechanical Properties: Rigorous testing for functionalities such as yield strength, tensile strength, and elongation, critical for operational safety.

3. Hydrostatic Testing: Ensures each tube is capable of withstanding internal pressures without failure, adhering to safety regulations.

4. Non-Destructive Testing: Recommended techniques to detect any anomalies or defects within the material that could compromise performance.

5. Marking and Certification: Every product is marked with relevant details, including heat number and specifications, ensuring traceability and quality assurance.
