ASTM A182 F304 Stainless Steel Heat Exchanger Tubesheet PT UT
A tubesheet is a plate, sheet, or bulkhead which is perforated with a pattern of holes designed to adapt pipes or tubes. These sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements. Tubesheets have different sizes and a series of holes are done to create a place where the tube ends are welded. It is also called tube plate.There are two types: floating tubesheet and stationary tubesheet.
Depending on the application, a tube sheet may be made of various metals or of resin composites or plastic.
A tubesheet may be covered in a cladding material which serves as a corrosion barrier and insulator and may also be fitted with a galvanic anode.
Tubesheets may be used in pairs in heat exchange applications or singularly when supporting elements in a filter.
How to judge the tubesheet quality?
The precision of tubesheet processing, especially the pipe hole spacing and pipe diameter tolerance, perpendicularity and finish, greatly affects the assembly and service performance of the above listed chemical equipment.
With the large-scale of chemical equipment and power station, the diameter of tubesheet is becoming larger and larger. The tubesheet with the diameter of 4m-5m is very common.
The characteristics of large tubesheet are large number of holes, dense, small diameter, deep, high precision and finish requirements.

What is a heat exchanger used for ?
Heat exchangers are used to give control over the temperature in various processes to increase efficiency, prevent overheating or other potential hazards, and to improve safety.
For example, an oil cooler cools down hot oil by passing cold water next to the hot oil tube. The heat from the oil is transferred into the cold water, reducing the temperature of the oil.
Wherever heat is being generated in a process, heat exchangers can be used to keep the process safe, as well as use the heat energy most efficiently. As there are so many different places they can be used, there are a lot of different varieties.
Designing a proper steam heat exchanger or steam heat tracing system first requires a full understanding of the operational characteristics where the system will function. Inadequate performance is most commonly attributed to a design engineer’s failure to consider all steam system characteristics. A thorough review should be conducted of the steam system’s operating parameters and documentation. Failing to understand the context of the application commonly results in inappropriate control or selection of system components.
