Stainless steel clad plate has been widely used in industrial scrubber, Stainless steel clad plate is solidly bonded and fused together through high temperature and high pressure to form bonds between atoms and never separate, and at the same time, it has good processability and can withstand repeated bending, shearing, punching,welding and other processing without stratified cracking.

Clad Plates for Air Pollution Control Equipment

Air pollution control and wastewater treatment systems are frequently exposed to moisture, acidic condensate, chlorides, abrasive solids and temperature fluctuations. These conditions can accelerate general corrosion, pitting, crevice corrosion and erosion-corrosion in conventional carbon steel equipment.

KLS supplies corrosion-resistant clad plates for industrial wet scrubbers, absorber towers, flue gas treatment systems and selected wastewater treatment equipment. The corrosion-resistant cladding protects the process-contact surface, while the carbon or low-alloy steel base provides the structural strength required for large industrial equipment.

This construction allows equipment manufacturers and EPC contractors to use high-performance alloy only where it is required, helping control material costs without relying on solid high-alloy plate throughout the complete structure.

Corrosion Challenges in Environmental Protection Equipment

Wet gas treatment equipment may be exposed to several corrosion mechanisms at the same time:

• ◆  Acidic condensate created when hot exhaust gas contacts cooler surfaces

• ◆  Chloride- and fluoride-containing liquids that promote localized corrosion

• ◆  Abrasive slurry, dust and suspended solids

• ◆  Repeated wet-dry cycles and temperature changes

• ◆  Corrosion around welds, crevices and liquid collection zones

Because conditions can vary significantly between the inlet, absorber, sump and outlet sections, clad plate selection should be based on the actual service medium and equipment location rather than the general industry name alone.

Applications of Clad Plate

Not every dry dust collector requires clad plate. It is most valuable in wet, condensing, acidic or chloride-bearing areas where ordinary carbon steel may experience premature corrosion.

Clad Material Options for Different Service Conditions

There is no single alloy suitable for every environmental protection system. KLS can provide different metal combinations according to the operating medium, temperature, structural load and fabrication requirements.

Final material selection should consider gas and liquid composition, pH, chloride and fluoride concentrations, temperature, pressure, solids content, fabrication method and required service life.

Why Use Clad Plate Instead of Solid Alloy?

Clad plate combines a corrosion-resistant working surface with a strong and economical steel backing. For large scrubber shells, absorber towers and process vessels, this can provide several advantages:

• ◆  Reduced consumption of costly stainless steel or nickel alloy

• ◆  Structural strength from the carbon or low-alloy steel base

• ◆  A metallurgical bond between the base and cladding layers

• ◆  Compatibility with cutting, forming and welding when qualified procedures are used

• ◆  Lower lifecycle and maintenance costs in properly selected applications

• ◆  Customized total thickness and cladding thickness for different equipment zones

Frequently Asked Questions

What clad plate is suitable for an industrial wet scrubber?

The selection depends on the chemical composition, pH, temperature, chloride level and abrasion conditions. Stainless steel clad plate may suit moderate service, while nickel alloy or Hastelloy clad plate may be considered for more aggressive environments.

Can clad plate be used in FGD absorber towers?

Yes. Clad plate can be used in selected absorber shells, ducts, sumps and downstream components. Each area should be evaluated separately because corrosion conditions vary throughout the FGD system.

Does every dust removal system require clad plate?

No. Dry, non-corrosive dust collectors may use conventional steel. Clad plate is more relevant where moisture, acidic condensate, chemicals or chloride-bearing media create a significant corrosion risk.

Can the clad plate be cut, bent and welded?

Yes. Metallurgically bonded clad plate can be processed into industrial equipment components. Qualified forming and welding procedures should be used to protect both bond integrity and the corrosion-resistant cladding layer.

Can KLS produce clad plate according to project drawings?

Yes. Base material, cladding material, plate dimensions, layer thickness and surface requirements can be customized according to drawings and technical specifications.
