タイトルまたは説明
Clad Steel Plate is a composite steel plate made by bonding
stainless steel plate (cladding material) to either or both sides
of carbon steel or low alloy steel plate (base metal). The
materials mostly composite carbon steel plate and stainless steel
plates. Clad steel plate mainly used in anti-corrosion and pressure
vessels manufacturing.
Features of Clad Steel Plate:
>Sufficient strength
>Heat resistance
>Corrosion resistance
>Wide range applications
Applications of Clad Steel Plate:
>Petrochemical,
>Pharmaceutical,
>Light industry,
>Automobile,
>Anti-corrosion usage,
>Pressure vessels manufacturing,
>Electrical construction,
>Exchangers and finned tubes,
>Equipments for waste water treatment and flue-gas
desulfurization
Etc.
Advantages of Clad Steel Plate:
Compared to austenitic stainless steels and alloys:
- Combine the high strength of the backing material with the
corrosion resistance of the cladding
- Weight savings - Lower cost - Better thermal conductivity and
lower thermal expansion
Compared to weld overlays:
- Homogeneity of chemical composition
- Better metallurgical structure than weld overlays
- Greater choice of grades :
1.Safe cladding of grades susceptible to hot
cracking
2. Cladding of materials forming an inter-metallic
phase with base metals
3.Cladding of ferritic grades
- Lower inclusion content compared to weld overlays
- Better surface quality, no grinding required
- Lower thicknesses of cladding (no dilution)
- Reduced costs of inspection and quality control
Compared to wall papering or frettings:
- **0% bonding of the total surface
- Resistance to pressure variations and vacuum
- Smooth surface, reducing deposits and condensates
- Easier field erection : lower risk of contamination of
cladding
- No pressure build up behind the corrosion resistant layer
Compared to organic coatings or plastic linings:
- Longer life
- Lower maintenance costs
- Structural stability, no aging
- Reliability
- Compact
- Better resistance to heat and fire
- External welds are possible without alteration of the corrosion
resistant layer
