Stainless steel tubes specifically designed for heat exchangers are vital components in various industrial applications, including pipelines and associated equipment. These tubes are utilized in numerous process industries, serving as essential elements for effective heat transfer.

Our heat exchanger tubes meet stringent industry requirements, characterized by bead worked welds, fixed lengths, and rigorous testing protocols. To ensure rapid delivery without compromising quality, we maintain an extensive strip stock that includes both standard and special grades of stainless steel, available in the most common thicknesses. With a broad selection of stainless steel grades, we leverage our extensive manufacturing experience to produce high-performance heat exchanger tubes.

Testing Criteria:
To ensure that our tubes meet and exceed industry standards, we conduct thorough testing following ASTM A213-09 and ASTM A1016 guidelines. The main testing parameters include:

1. High Pressure Hydraulic Test: Minimum 10 MPa.
2. Eddy Current Test: To detect surface defects.
3. Ultrasonic Test: For assessing internal quality.
4. Mechanical Test: Evaluating yield strength and tensile strength.
5. OD and WT Tolerance Test: Ensuring dimensional accuracy.

Tubes End Finishes:
Our heat exchanger tubes can be supplied with plain ends, square cuts, and, upon request, deburred for enhanced safety and usability.

Applications:
Our stainless steel tubes are widely applied in critical industries, including:

• Nuclear Industry: Reliable and stable performance under extreme conditions.
• Chemical Industry: Resistance to corrosive substances and high temperatures.
• Petrochemical Industry: Essential for refinery processes and heat recovery systems.
• HVAC (Heating Ventilation Air Conditioning) and Refrigeration: Effective in heat transfer and energy efficiency.
• Food and Beverages: Complying with hygiene standards and providing a safe transfer of fluids.
• Power Generation: Used in various systems for both renewable and conventional energy production.
