Tubesheet, SA516 GR70+N Tubesheet

A tubesheet is a round steel plate with holes drilled in it that are slightly larger than the outer diameter of the tubes. It is a round steel component in a heat exchanger that fixes the tubes and seals the medium. The tubes are inserted and welded to fix them, and it acts as such a fitting. The precision of tubesheet processing, especially the hole spacing and tube diameter tolerances, perpendicularity, and finish, greatly affect the assembly and performance of the chemical equipment listed above. Henan Beibang specializes in the production and customization of various tubesheets. Our core competitive advantages are as follows: Technical Advantages We use processes such as [CNC deep hole drilling/laser cutting], with hole position accuracy up to ±0.02mm, ensuring 100% matching with the heat exchange tubes and no leakage. Materials cover carbon steel, stainless steel, Hastelloy, etc., and are certified by ASME/GB150 to meet extreme working conditions. Customization Capabilities We support non-standard designs and can provide [special-shaped tubesheet/multi-layer composite structure] solutions based on your equipment drawings, shortening the delivery cycle by 30%. Quality Assurance Full-process UT testing + third-party flaw detection report, providing a 10-year warranty commitment, with an accident rate 90% lower than the industry average.
