Flexible tube-rccn

Flexible tube

RZ basic type
Product structure: Outer layer of hot-dip galvanized steel strip (FeZn) (special Dacromet galvanizing process) Inner layer of flame-retardant and anticorrosive insulation layer
Application scope: dry places and piping buried in concrete (such as decoration ceiling, fire protection, lighting, instrumentation, electrical equipment installation engineering)
Performance characteristics: flexible, water-resistant, anti-corrosion, flame-retardant, insulation and safety
Explanation: Use the basic accessory piping: the inner wall insulation is non-toxic, harmless and environmentally friendly
waterproof type
Product structure: outer soft polyvinyl chloride (PVC)
Middle layer hot-dip galvanized steel strip
Special resin inside
Scope of application: indoor and outdoor humid places (both light and dark) places with water vapor places with acid and alkali corrosion, direct burial, etc.
Performance characteristics: In addition to the basic characteristics, there are water resistance, corrosion resistance, chemical resistance, etc.
Explanation: Use waterproof accessory piping: inner wall insulation layer is non-toxic, harmless and environmentally friendly
Flame retardant
Product structure: outer layer of soft polyvinyl chloride (PVC) inner layer of special resin
Scope of application: indoor and outdoor wet places (both light and dark) electrical construction places with high fire protection requirements, automatic fire alarm systems, etc.
Performance characteristics: In addition to the basic and waterproof characteristics, flame retardant and strong fire performance
Explanation: Use waterproof accessory piping: inner wall insulation layer is non-toxic, harmless and environmentally friendly
