11 month agoThe scientific name of PVC pipe material is polyvinyl chloride, which is a thermoplastic resin material with excellent mechanical properties and a tensile strength of about 60MPa. Adding some auxiliary agents during the pipe making process can make PVC pipe and fittings have flame retardant, acid and alkali resistance, wear resistance, and the most important insulation properties for PVC conduit. It is these excellent characteristics that make PVC conduit occupy a huge market.

3. For fire protection distribution lines and electrical circuits of fire automatic alarm systems, it is mandatory to use flame-retardant PVC conduit that meets the standards of the Ministry of Public Security
4. For the renovation of exposed electrical circuits in cultural relics and ancient buildings, indoor decoration and secondary decoration of houses, as well as the renovation of old and old buildings that require the use of exposed circuits (hidden in ceilings and floors), flame-retardant PVC conduit with combustion performance of B1 or above must be used.
