PVC RIGID CONDUIT

RIFENG offers a complete line of PVC rigid conduit and fittings which is made of high quality raw materials. For commercial, residential and industrial, RIFENG PVC rigid conduit is proven durable and effective for years of maintenance-free performance in underground.

Technical specification

Corrosion Resistant
Resistant to most chemicals, PVC is typically not affected by corrosive soils.And the conduit can be buried in concrete.
Non-conductive
Good insulation, able to resist AC2000V voltage and insulation resistance more than 1x10 Ω.
Self-Extinguishing
Properties make PVC fire resistant.
Impact Resistant
Tough, durable, with high tensile strength, yet easy to install and can be bent by spring under normal temperature.
Attracting appearance
Even color, good appearance, suitable for indoor installation.

 

RIFENG PVC Conduit pipes in accordance with standard IEC-61386.
