EN10028 1.4541 / A182 F321 Tubesheet Stainless Steel Heat Exchanger Tube Plate

EN10028 1.4541 / ASTM A182 F321 Stainless Steel Forged Tubesheet for Heat Exchanger

EN10028 is a European standard for flat products made of steels for pressure purposes. It specifies requirements for flat products for pressure equipment made of stainless steel. The material 1.4541 is equivalent to ASTM/ASME grade 321 stainless steel.

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.

Other Materials

One of the most common heat exchangers in service within industrial process applications is the “Shell & Tube Heat Exchanger”.
They are available in many shapes, sizes and have been used in industry for over 150 years. In this exchanger group are various
sub design types: Fixed, U-tube and Floating tubesheet. Variations of all can be denoted as type “E”, “F”, “G”, “H”, “J”, “K” or “X”.
The main applications are where high pressure/temperatures are key considerations. Loosely, general designs consist of the or an
outer shell in which resides a tube bundle (these can be configured as finned, plain etc) sealed at each end by a tube sheet which
isolates the tubes and the outer shell.

Shell & tube heat exchangers have the capability to transfer large amounts of heat at low(er) costs. This, in principle, down to both

design simplicity and effectiveness – large tube surface for reduced weight, volume of liquid and importantly floor space.

Where are shell and tube heat exchangers used?

Tubular heat exchanger

Boiler, Pressure vessel

Steam turbine

Large central air conditioning
