Description

PVC-C is a plastic produced through post-chlorination of PVC (polyvinyl chloride), significantly enhancing flame retardancy while offering exceptional chemical and heat resistance.

Specifications

Standard:DL/T 802.3-2023

Size: DN100-250

Features & Benefits

1. High Insulation:
Effectively isolates electrical current, ensuring system stability and personal safety.

2. High Mechanical Strength:
Excellent ring stiffness; PVC-C is the only plastic power conduit material requiring ring stiffness testing at high temperatures (80°C).

3. Exceptional Flame Retardancy:
Self-extinguishing ( extinguishes immediately upon ignition), complying with Combustion Performance Class B1 (Class B per EN 13501-1).

4. Superior Heat Resistance:
Vicat softening point >93°C, suitable for installation near thermal pipelines or in high ambient temperatures.

5. Corrosion & Aging Resistance:
Resists acids, alkalis, salts, and humid environments; exhibits strong UV resistance and long service life.

6. Low Friction Coefficient:
Smooth inner wall minimizes cable threading resistance, improving installation efficiency.

Scope of Application

Municipal construction: Power pipelines for urban main and secondary roads.

Residential community: Distribution network, household cable protection.

Industrial park: Cable laying inside and around the factory area.

Transportation hub: Supporting power engineering for airports, stations, and subways.

New energy projects: Cable collection lines for solar power plants and wind farms.

Farmland water conservancy: Electricity supply for machine wells and protection of agricultural irrigation cables.

FAQ

Q1: What are the recommended fusion welding temperatures for PE and PP-R pipes?

What are the recommended fusion welding temperatures for PE and PP-R pipes?
Q2: What are the maximum service temperatures and pressures for PE and PP-R pipes in water supply systems?

"PE pipes have a maximum service temperature of 40°C and a pressure rating of 1.6 MPa. PP-R pipes have a maximum service temperature of 70°C and a pressure rating of 1.0 MPa"
Q3: What are the available pressure ratings for PE pipes, and which are the most commonly used?

"PE pipes are available in eight pressure ratings, ranging from PN0.4 to PN2.0. The most commonly used ratings are: PN0.6, PN0.8, PN1.0, PN1.25, and PN1.6."
Q4: What are the standard pipe lengths for PE pipes, and how can the length be customized?

"PE pipes are supplied in both coils and straight lengths. Coiled pipes are typically supplied in 100-meter rolls. Straight pipes are generally 6 meters per length. Customized lengths are also available upon request, such as 9 meters or 12 meters per coil, depending on customer requirements."
Q5: What types of PE fittings are available, and how should they be selected?

"There are three main types of PE fittings: Socket fusion fittings (recommended for sizes DN20 to DN110) Butt fusion fittings (commonly used for sizes above DN110) Electrofusion fittings, which are commonly used in standard water supply systems and are typically applied in maintenance and repair scenarios."
