At Haihao Group, we prioritize quality assurance in every manufacturing process. Rigorous quality inspection is essential to ensure that these products meet the required specifications and operate reliably in their intended applications. Recently, we conducted strict quality inspections on the special-shaped tube sheets produced for our Russian client, focusing on the following key inspection metrics:

Special Shaped Tube Sheet

1.Hole Positioning: The accurate positioning of holes is crucial for the proper assembly and functionality of the tube sheets. Misalignment can lead to inefficient fluid flow and compromised structural integrity. By ensuring that the holes are precisely located according to design specifications, we guarantee that the tube sheets will fit seamlessly with the connected pipes.

2.Hole Diameter Tolerance: Each hole’s diameter must adhere to specific tolerances. Deviations can affect the sealing capabilities and overall performance of the piping system. Our inspections ensure that the hole diameters are within acceptable limits, facilitating a proper fit for the tubes.

3.Roughness of Tube Sheet Holes: Excessive roughness in the holes can reduce the sealing performance at the expansion joints, while too low roughness can decrease the contact friction and reduce pull-out resistance. Therefore, it is essential to strictly control the roughness of the tube holes. We conducted rigorous quality checks on roughness, and the results met the client’s standards.

At Haihao Group, our strict quality inspection process for special-shaped tube sheets highlights our commitment to excellence. By focusing on key parameters such as hole positioning, diameter tolerance, and hole roughness, we ensure that our products perform reliably and efficiently in their intended applications. This dedication to quality not only supports our clients’ operational needs but also enhances their confidence in us as a leading manufacturer in the industry.
