Haihao Group successfully produces special-shaped tube sheet for Russian client

Haihao Group is pleased to announce the successful production of special-shaped tube sheets for our Russian client. This project involved several technical complexities, such as intricate hole treatments, beveling techniques, and unconventional shape designs. Our dedication to precision and quality enabled us to meet these challenges head-on, delivering products that fully adhered to the client’s requirements.

Special Shaped Tube Sheet

Production Challenges

Specialized Hole Treatments:
The tube sheets required highly accurate hole placements, differing significantly from typical designs. Each hole was carefully drilled to prevent deformation, ensuring that the holes met the structural needs specified by the client. This demanded the use of advanced machinery and stringent quality control processes to ensure the positions and accuracy of the holes were perfectly aligned with the project’s requirements.

Beveling Techniques:
The tube sheets included welding bevels around the holes to facilitate seamless welding. Achieving these bevels required precision machining to meet industry standards. Accurate angle calculations were essential to support strong welds and reduce the possibility of defects during the welding phase.

Unique Shape Design:
The distinctive external shape of the tube sheets added to the complexity of the project. Our design team worked closely with the client to understand their specific needs and used CAD modeling to bring the final product to life. This collaborative process ensured that even the most intricate geometries were successfully incorporated into the manufacturing process, achieving the desired functionality and fit.

Material Performance

The batch of custom-shaped tube sheets was manufactured using SA 182 F321, a material known for its exceptional properties:

• Corrosion Resistance: F321 provides outstanding protection in various corrosive environments.
• High-Temperature Durability: This material maintains its strength and stability under high-temperature conditions, making it ideal for demanding environments.
• Weldability: The low carbon content of F321 enhances its ability to be welded, ensuring strong, durable joints, essential for the integrity of the tube sheets.
• Resistance to Sensitization: F321 is specifically engineered to reduce the risk of sensitization, which can cause intergranular corrosion, particularly in high-heat applications.

Through the combination of our expertise in precision hole treatments, beveling techniques, and complex design solutions, along with the high performance of SA 182 F321, Haihao Group successfully navigated the technical hurdles of this project. We continue to strive for innovation, providing top-quality products that help our clients operate more efficiently.
