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.
