4. Conclusions There are cracks in all cold and hot tubesheets of the heat exchanger. Cracks in hot tubesheets are not expected to propagate in service, but the cold sheets are seriously damaged. The interstice between tubesheet and tube is in some cases open, indicating that the seal set by design is not always successful.
316L stainless steel sheet 2B finish has a mill finish, which is smooth and NOT the brushed finish commonly seen on kitchen appliances. Our 316L stainless steel sheet 2B finish will not have a protective film to prevent scratching, so the 316L stainless steel will commonly have scratching (not gouging) from when it is cut to size, fabricated, shipped, etc.

A U-tube heat exchanger only requires one tube sheet because the tubes leaving the tube sheet are bent at the end of the exchanger and returned to the same sheet. The third type is the floating head. This requires two tubesheets; one, which is fixed to the shell, and a second, which is located at the other end but is not fixed, allowing for , big weighing packaging line system
There are different grades and surface finishes of stainless steel to suit the environment to which the material will be subjected in its lifetime. Common uses of stainless steel are cutlery and watch straps. Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture.

Discussion. Tubesheet corrosion is generally caused by dissimilarities between higher alloy, more noble tube material, and the tubesheet metal. This situation is becoming more and more prevalent as high-stainless steel and titanium tubes are being retrofitted into older condensers and heat exchangers.
