Customization Stainless Steel Condenser Tube Sheet ASME SA182 F304/304L F316/316L

A stainless steel tubesheet is a crucial component in heat exchangers, condensers, and other shell-and-tube equipment. It serves as a structural element that holds the tubes in place, separates the shell-side and tube-side fluids, and ensures efficient heat transfer. Stainless steel is a popular material for tubesheets due to its excellent corrosion resistance, mechanical strength, and durability in demanding environments.

Common Stainless Steel Grades Used for Tubesheets

Austenitic Stainless Steels:

304/304L (UNS S30400/S30403):

Applications: General-purpose heat exchangers, food processing, and chemical industries.

Properties: Good corrosion resistance, excellent formability, and weldability.

Composition: Chromium (18-20%), Nickel (8-10.5%), Carbon (0.08% max for 304, 0.03% max for 304L).

316/316L (UNS S31600/S31603):

Composition: Chromium (16-18%), Nickel (10-14%), Molybdenum (2-3%), Carbon (0.08% max for 316, 0.03% max for 316L).

Properties: Superior corrosion resistance, especially against chlorides and acidic environments, due to molybdenum content.

Applications: Marine environments, chemical processing, and pharmaceutical industries.

Ferritic Stainless Steels:

409 (UNS S40900):

Composition: Chromium (10.5-11.75%), Carbon (0.08% max).

Properties: Moderate corrosion resistance, good thermal conductivity, and lower cost.

Applications: Automotive exhaust systems and low-pressure heat exchangers.

430 (UNS S43000):

Composition: Chromium (16-18%), Carbon (0.12% max).

Properties: Good corrosion resistance in mild environments, magnetic, and cost-effective.

Applications: Appliances, automotive, and low-corrosion environments.
