Product Description
Corrosion Resistant Stainless Steel Cladding Material For Pipeline Cold Insulation
Stainless steel metal layer serves as a protective material in pipeline cold insulation engineering. When combined with thermal insulation materials, moisture-proof treatment, and proper construction specifications, it delivers efficient cold insulation, corrosion resistance, and structural stability.
Function and Selection of Stainless Steel Metal Layer
Protective Layer Functions: 0.5mm thick stainless steel plate wraps cold insulation materials to provide:
- Mechanical protection against external impacts and friction
- Moisture-proof barrier and corrosion resistance, especially against chloride ions
- Continuous sealing through lap or bite joints to minimize cold loss
Applicable Scenarios:
- Low-temperature pipelines (LNG, chilled water systems) withstanding -180°C to ambient temperature differences
- Highly corrosive environments (chemical plants, coastal areas) where stainless steel outperforms carbon steel
Cold Insulation System Structure Design
Material Combination:
| Component | Materials | Specifications |
|---|---|---|
| Thermal insulation layer | Polyurethane foam (PIR/FIR), foam glass (FG), nitrile rubber foam | Low thermal conductivity, high compressive strength |
| Moisture-proof layer | Bitumen mastic or waterproof mortar | 5mm thickness |
| Protective layer | Stainless steel plates | Fixed through embossing, lapping (30-50mm overlap) or embedded joints |
Key Construction Specifications:
- Joint treatment: Longitudinal joints use embossing/lapping, circumferential joints use bite/plug joints
- Fixing methods: Metal hoops (250-300mm spacing) for cold insulation; self-tapping screws (150-200mm spacing) for thermal insulation
- Special parts: Elbows require adjusted lap lengths based on outer diameter; tees fixed with flanging
Corrosion and Moisture-proof Measures
Metal Surface Treatment:
- Pre-coating with phosphating primer or epoxy coating enhances adhesion
- Avoid chloride-containing sealing materials to prevent stress corrosion cracking
Moisture-proof Layer Construction:
- Waterproof mortar or glass fiber cloth forms closed barrier
- Sealing tape required for joints in humid/outdoor environments
Construction Precautions
Environmental Adaptability:
- Extreme cold (-30°C) requires 316L stainless steel and increased insulation thickness
- Dynamic stress areas (valves, elbows) need elastic cold insulation materials
Quality Control:
- Cold insulation layer thickness deviation ≤ ±5%
- Surface flatness: ≤3mm gap under 2m straightedge
- Post-construction testing includes vacuum and refrigerant penetration tests
Typical Applications
- LNG pipeline cold insulation: Polyurethane foam + stainless steel with staggered lapping
- Food industry refrigerant pipes: Foam glass inner layer with stainless steel outer layer
Note: All construction must comply with "Industrial Equipment and Pipeline Thermal Insulation Engineering Construction Specification" (GB 50126) and project design requirements.
