ASTM SA266 GR.2N Channel Cover Flange Tube Sheet For Heat Exchanger Parts

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

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].
