Titanium Clad Tubesheets

Titanium clad tubesheets are critical components in heat exchangers and pressure equipment, combining a structural base metal (carbon steel or stainless steel) with a corrosion-resistant titanium layer.

This bimetallic design delivers:

• The strength and cost-efficiency of steel

• The excellent corrosion resistance of titanium

They are widely used in chemical processing, oil & gas, power generation, and marine systems, especially in environments prone to pitting, crevice corrosion, and stress corrosion cracking.
