PVC Conduit Pipe
Product Description
Standard: JG/T3050-1998
Colors: White and other colors upon request
Length: According to customer's requests
Advantages:
1. Non-conductive: Good insulation, able to resist 25kv voltage, assuring a safe system
2. Fire Resistance: Self-extinguishing, do not support combustion
3. Corrosion Resistance: Resistance to acids, bases and salts, assuring a lower maintenance cost and a longer performance life
4. High resistance to pressure, conduit of MID size can stand above 750N pressure and can be externally installed or buried in concrete avoiding any damage caused by pressure.
5. Impact Strength: Resistant to compressing and impact, suitable to be buried in concrete
6. Easy installation. The conduit less than de32mm can be easily cut off by pipe cutter. Inserting relevant special spring into conduit, it can be bent into needed angle under normal temperature. Pipeline meeting the construction shape will be formed to connect conduits with PVC adhesive.
Applications:
Protect and manage indoor electrical wiring

1 Voluntary standards JG/T3050-1998
2 Appearance Both the inside and outside surfaces of the pipes should be smooth, without blowholes, overt openings or unidenticl color. The mouth of pipes should have smooth edges so as not to scratch the insulating layer of cables. The color is white.
