Yuhong Group Co., Ltd. is a premier manufacturer in the heat transfer equipment industry. With years of engineering experience, we specialize in the design and fabrication of heat exchangers, pressure vessels, and air coolers. Our core strength lies in our precision manufacturing of heat transfer components, specifically in high-pressure tubesheet and heat exchanger tube assemblies.
The ASME SA 266 Gr.2N Stationary Tubesheet is a critical structural component designed for fixed-tubesheet heat exchangers and high-pressure vessels. Engineered to withstand significant differential thermal expansion and internal pressures, this component serves as the mechanical anchor for the tube bundle, ensuring structural integrity in demanding industrial processes.
We strictly adhere to the ASME Section II material standards. The SA 266 Gr.2N forging is selected for its excellent weldability and high-temperature tensile strength.
| Component | Material Standard | Grade | Application Feature |
|---|---|---|---|
| Stationary Tubesheet | ASME SA 266 | Gr.2N | Optimized for pressure vessel fabrication |
| Tube Hole Finish | ASME/TEMA | - | Enhanced sealing surface integrity |
| Gasket Surface | ASME B16.5/B16.47 | - | High-precision serrated finish |
To ensure the reliability of the tubesheet under cyclic stress, we implement a comprehensive quality control protocol:
| Test Item | Standard/Method | Acceptance Criteria |
|---|---|---|
| Ultrasonic Inspection | ASME SA 388 | No linear indications allowed |
| Dimensional Tolerance | TEMA RCB-7 | Strict adherence to hole pitch accuracy |
| Hardness Testing | ASME SA 266 | HBW 131-187 range |
| Hydrostatic Testing | ASME Section VIII | 1.3x Design Pressure |
A: Ligament cracking is often caused by thermal stress during the tube-to-tubesheet welding process. We mitigate this through pre-heating procedures defined by ASME standards and by strictly controlling the weld heat input based on the specific ligament width of your design.
A: Unlike lower-grade carbon steels, Gr.2N provides superior grain refinement and consistent mechanical properties at elevated temperatures, which are essential for long-term fatigue resistance in fixed-tubesheet designs.
A: Yes. We accommodate various TEMA configurations (Fixed, U-tube, or Floating Head) and can manufacture tubesheets to custom drawing specifications, including triangular or square pitch layouts.
