HEAT EXCHANGER PARTS SA266 GR.2N CARBON STEEL TUBESHEET THREAD HOLE
Description:
A tubesheet is usually made from a round flat piece of plate,sheet with holes drilled to accept the tubes or pipes in a accurate location and pattern relative to one another.The tube sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements.Tubes are attached to the tube sheet by hydraulic pressure or by roller expansion.
ASTM A266 grade 2 is a type of ASTM A266 carbon steel. Cited properties are appropriate for the normalized condition. The graph bars on the material properties cards below compare ASTM A266 grade 2 to: wrought carbon or non-alloy steels (top), all iron alloys (middle), and the entire database (bottom).
