X6CrNiMoTi17-12-2 1.4541 EN10028-7 Forged Tubesheet for Heat Exchanger
A tubesheet， the plate that forms the sealing surface at the end of a shell and tube heat exchanger or a pressure vessel. It provides a surface for the tube ends to be welded or secured to create a leak-proof joint. Such tubesheets are used in various industries， including petrochemical， chemical， and power generation， where corrosion resistance and high-temperature properties are required.
EN 10028-7 was originally published in 2000. The second edition， BS EN 10028-7:2007， replaced BS EN 10028-7:2000， which was withdrawn on January 31， 2008 by BSi. The third and current edition was published in 2016， replacing the 2007 edition， which has now been withdrawn.
