Explosive Welding Clad Tubesheets Plates For Heat Exchanger

Explosive welding Clad metals are a low-resistance, high-strength joint that allows the welding of two dissimilar metals. They are for use in high-current, high-temperature, and mechanical stress environments. The explosive welding creates dissimilar metals into metallurgically bonded. Dissimilar metals are permanently joined for 100% electrical continuity, and demonstrate the characteristics of contiguous metal at the bond interface.

Advantages of explosive welding clad tubesheets plates for heat exchangers

1. Corrosion resistance: The cladding material provides excellent corrosion resistance, protecting the tubesheet from the corrosive effects of the heat transfer fluid. This can extend the service life of the heat exchanger and reduce maintenance costs.
   • For example, in applications where the heat transfer fluid is acidic or contains corrosive chemicals, a stainless steel or titanium cladding can prevent corrosion and ensure reliable operation.
2. Strength and durability: The base metal provides the necessary strength and durability to support the tubes and withstand the mechanical stresses of the heat exchanger. Carbon steel is commonly used as the base metal due to its high strength and low cost.
   • The combination of the cladding and base metal results in a plate that is both corrosion-resistant and mechanically strong, making it suitable for demanding heat exchanger applications.
3. Cost-effectiveness: Explosive welding clad plates can be a cost-effective solution compared to using solid corrosion-resistant materials. By using a thin layer of cladding on a base metal, the overall cost of the tubesheet can be reduced while still providing the required corrosion resistance.
   • This is particularly beneficial in large-scale heat exchanger applications where material costs can be a significant factor.
4. Customization: Explosive welding allows for the customization of the cladding thickness and material to meet the specific requirements of the heat exchanger application. This flexibility enables designers to optimize the performance and cost of the tubesheet.
   • For example, different cladding materials can be selected based on the corrosivity of the heat transfer fluid, and the cladding thickness can be adjusted to provide the desired level of corrosion protection.
