The petrochemical and chemical container equipment manufacturing industry has long been a traditional stronghold for the application of titanium - steel composite plate materials, consistently ranking at the top in terms of their usage volume. Titanium demonstrates remarkable stability across a wide range of acidic, alkaline, and saline conditions commonly encountered in the chemical sector. Moreover, titanium - steel clad plates play an indispensable role in petroleum refining facilities and chemical plants. Thanks to titanium's unique ability to resist corrosion from substances such as chlorine dioxide, chlorous acid, and chlorite, these composite panels hold particular significance in the bleaching equipment used in the textile printing, dyeing, and paper - making industries.

Marine and Chloride Environments

Titanium and its alloys display outstanding resistance to seawater, chloride solutions, and fluid - induced erosion. In salt production, the utilization of titanium - steel composite plates for evaporation chambers can effectively mitigate corrosion. This not only prevents the accumulation of salt on the walls of evaporation tanks but also extends the production cycle, enhances the quality of salt, and substantially reduces equipment costs for salt plants.

Seawater Desalination

In the realm of seawater desalination, titanium and its alloys are highly regarded due to their exceptional resistance to corrosion from seawater and chloride solutions, as well as fluid erosion. Additionally, titanium is non - toxic and harmless. As a result, titanium - steel composite panels emerge as the perfect choice for seawater desalination equipment.

Manufacturing of Nuclear Power Equipment

In the manufacturing of nuclear power equipment, thick - cladded (with a cladding thickness of ≥8 mm) and large - width (single - sheet area of ≥20 m²) titanium - steel clad plates serve as the primary materials for condenser tube sheets. There is a substantial demand for these materials, and given their unique properties and durability, they hold great promise for future applications.

Titanium - steel composite panels are also employed in the bleaching treatment tanks of paper mills and the harsh treatment tanks containing sodium hypochlorite and hydrochloric acid in sewage treatment plants. Titanium is favored because of its excellent corrosion resistance, minimal ion dissolution in seawater environments, non - toxic nature, and lack of environmental pollution, making it the preferred material for marine structures.

Titanium exhibits outstanding corrosion resistance in flowing seawater, positioning it as an ideal anti - corrosion material for marine structures. Currently, there are two main approaches to utilizing titanium for this purpose. The first involves combining titanium sheets with organic anti - corrosion materials to create composite cladding materials. The second method entails using titanium - steel composite plates, which are clad and welded onto new constructions. Titanium - steel clad plates have been in use for over four decades, primarily in applications like condenser tube sheets. Furthermore, their application in marine civil engineering is gradually gaining momentum, presenting new opportunities. These clad plates effectively combine the superior corrosion resistance of titanium with the strength of steel, achieving an optimal balance between performance and cost. There is significant potential for further development in this area in the future.

Titanium - steel clad plates possess excellent corrosion resistance and strength, making them an ideal choice for manufacturing equipment intended for use in corrosive environments. As the production processes of titanium - steel clad plates continue to improve, their applications are expected to become increasingly widespread and common.
