ASTM SA266 GR.2N Channel Cover Flange Tubesheet
What is tubesheet ?
A tube sheet is a plate which is used to support the tubes in a shell-and-tube heat exchanger. The tubes are aligned in a parallel way, and supported and held in place by tube sheets. The tube sheet is a circular plate which is perforated so that the tubes can fit through the openings.
Description
ASTM SA266 GR.2N is a specification for carbon steel forgings for pressure vessel components. In this context, a Channel Cover Flange Tubesheet would refer to a component used in the construction of heat exchangers or pressure vessels.
The Channel Cover Flange Tubesheet would typically be made from ASTM SA266 GR.2N material, which is a low carbon steel grade suitable for high temperature and pressure applications. This material offers good strength and corrosion resistance, making it a suitable choice for use in demanding environments.
The ASTM SA266 GR.2N Channel Cover Flange Tubesheet would be a critical component in the construction of pressure vessels, ensuring the e and efficient operation of the equipment. It is important to ensure that the material and design specifications meet the required standards for the specific application.
Chemical Composition Requirements
| Item | Chemical Req. for ASTM A266, % | ||
| Gr. 1 & 2 | Gr. 3 | Gr. 4 | |
| C | ≤ 0.30 | ≤ 0.35 | ≤ 0.30 |
| Mn | 0.40~1.05 | 0.80~1.35 | 0.80~1.35 |
| P | ≤ 0.025 | ≤ 0.025 | ≤ 0.025 |

| Si | 0.15~0.35 | 0.15~0.35 | 0.15~0.35 |
Heat Treatment
After forging and before reheating for heat treatment, the forgings in accordance with ASTM A266 shall be cooled in such a manner as to prevent injury and to accomplish transformation. All the ASTM A266 forgings shall be heat treated by one of the four processes: annealing, normalizing, normalizing and tempering, or liquid quenching and tempering. When tempering is performed, it shall be at a subcritical temperature, but no less than 1100°F [595°C].
