PVC-C (Chlorinated Polyvinyl Chloride) contains an elevated chlorine concentration (typically 63%–67%) compared to standard PVC-U (~56.7%). This structural chlorination elevates the Vicat softening temperature from ~78°C up to ≥ 93°C–105°C. When high-voltage transmission cables operate under sustained peak loads, or during short-circuit thermal surges where copper/aluminum core temperatures spike, PVC-U pipes risk thermal deflection and structural collapse. PVC-C preserves ring stiffness and crush protection under continuous 90°C underground operation.

Yes. Our industrial PVC-C power conduits are manufactured to high ring stiffness standards (SN8, SN10, and SN16 classes) with high tensile yield strength (≥50 MPa). When buried in standard municipal trenches with properly graded granular gravel or sand compaction, they absorb dynamic soil and vehicular wheel loads without requiring expensive concrete pouring or encasement, cutting total project civil construction costs substantially.

We supply two standard joint configurations: (1) Flexible Elastomeric Rubber Ring Expansion Sockets (R-R type), engineered with precision-formed internal grooves that accommodate thermal expansion/contraction while sealing up to IP68 against groundwater ingress; and (2) Tight-tolerance Solvent Cement Spigot-and-Socket joints (T-S type), providing rigid permanent fusion bonding ideal for dry subterranean duct banks.

PVC-C has a Limiting Oxygen Index (LOI) exceeding 60%, meaning it requires over 60% ambient oxygen to support combustion (atmospheric air contains only 21%). It is classified UL 94 V-0 flame retardant and self-extinguishes within seconds once the external ignition source is removed. Furthermore, the specialized dense formulation does not emit rodent-attracting plasticizers, and high surface hardness completely resists termite and rodent gnawing.

Yes. Operating across 1,500 acres of production and logistics facilities in Tianjin and Tangshan, HZXY specializes in comprehensive turnkey project supply. EPC contractors can consolidate H-beams, structural angles, deformed reinforcement bar, hot-dip galvanized conduits, industrial pipeline valves, and PVC-C/PE pipes in a single commercial invoice, reducing customs handling and minimizing dead container space.

Every production batch is accompanied by comprehensive Mill Test Certificates (MTC) detailing ring stiffness, Vicat softening temperature, tensile modulus, drop-weight impact resistance at 0°C, and dimensional concentricity. We routinely support SGS, Bureau Veritas (BV), Intertek, and TÜV third-party visual, dimensional, and laboratory inspections prior to container dispatch from Tianjin Port.
