EN10222-4 P280GH, 1.0426 Carbon Steel Tubesheet For Shell And Tube Heat Exchangers
EN10222-4 P280GH, 1.0426 Carbon Steel Tubesheet For Shell And Tube Heat Exchangers
EN10222-4 is a European standard that specifies requirements for steel forgings for pressure purposes. P280GH is one of the materials covered by this standard. It is a non-alloy quality steel with elevated temperature properties. The "P" stands for pressure, and the number "280" indicates the minimum yield strength in megapascals (MPa).
A tubesheet is a component used in heat exchangers and boilers that holds the tubes in place. It is an important part of the structure as it provides support and facilitates the exchange of heat between the tubes and the surrounding fluid.
