ASME SA266 Gr.2N FK Carbon Steel Tubesheet， Channel Cover Flange For Heat Exchanger
ASTM A266 / ASME SA266 Gr.1/Gr.2/Gr.3/Gr.4 is a specification of carbon steel forgings， like tubesheets， channel flanges for for pressure vessel components. TONG CHUANG GROUP has supplied these carbon steel tubesheets and flanges for many yesrs with high quality， which are widely used in industries like oil & gas plants， offshore oil drilling， chemical industry， etc..
The tubesheet is one of the key components in a shell & tube heat exchanger.Depending on the tube bundle configuration， a heat exchanger can be equipped with one or two tubesheets.These tubesheets are usually made of low carbon steel material， with a varying thickness based on the fluid pressure. In view of the final applications (like petrochemical， nuclear， oil & gas， etc.)， the tubesheet can be cladded with stainless steel or other super alloys or even be entirely made out stainless steel or superalloys.
