Buried PVC Information Pipe

Core Features

1. Made of modified rigid PVC with thickened solid-wall / medium structure, specially designed for underground external pressure resistance. The pipe is integrally formed without coating, eliminating weak points in local protection.

2. Equipped with special rubber ring socket sealing connection, suitable for underground humid environments, providing waterproof, seepage-proof, and anti-sediment performance.

3. Full coverage of small and medium diameters (mainly dn20~dn110), with precise dimensions and small-angle cold bending ability to adapt to complex underground trench routes.

4. Added with moisture-resistant and anti-aging additives, enabling long-term underground resistance to moisture and microbial erosion without swelling, cracking, or chalking.

5. Ultra-smooth inner wall without burrs for long-distance underground cable pulling. The outer wall resists friction from soil and sand, and is not easily damaged during construction.

Key Properties

1. Stable electrical insulation: High dielectric strength and volume resistivity effectively isolate stray current in soil and avoid electromagnetic interference from underground power lines, preventing signal crosstalk and attenuation to ensure stable underground weak current transmission.

2. External pressure and impact resistance: Ring stiffness of SN4~SN8, able to withstand long-term static soil load and slight dynamic load on park and rural roads. Resists damage, collapse, and diameter shrinkage from sand extrusion and minor construction impacts.

3. Excellent sealing and waterproofing: Rubber ring socket connection achieves zero leakage, completely blocking groundwater and sediment from entering the pipe to avoid cable immersion, abrasion, and aging.

4. Corrosion and temperature resistance: Withstands weak corrosive media such as acid, alkali, salt, and sulfide in ordinary soil without additional anti-corrosion treatment. Operating temperature ranges from -10℃ to 70℃, maintaining stable dimensions without softening or brittleness underground.

5. Good underground aging resistance: Resists underground moisture, soil corrosion, and microbial erosion with stable performance for long-term underground use.

6. Reliable cable threading protection: Ultra-smooth inner wall reduces friction during cable pulling, effectively protecting cable sheaths and insulation layers from damage in underground construction.

Core Advantages

1. Precisely adapted for underground conditions: Triple enhanced performance in external pressure resistance, waterproofing, and soil corrosion resistance solves the problems of deformation, leakage, and aging of ordinary PVC pipes used underground.

2. Convenient and efficient construction: Fast rubber ring socket connection and easy cutting require no professional hot-melting or welding equipment, enabling manual operation suitable for scattered underground trench construction.

3. High cost performance: Much lower material and construction costs than HDPE and ABS underground pipes. Maintenance-free for anti-corrosion and waterproofing, resulting in low life-cycle cost.

4. Reliable protective structure: Integrally formed without coating, avoiding coating peeling and local corrosion. Consistent protection performance for the pipe body and joints.

5. Complete specification adaptability: Covers mainstream diameters for underground main and branch pipes, flexibly selectable according to cable quantity and laying distance for intensive installation.

6. Excellent signal protection: Insulation performance adapts to complex underground electromagnetic environment, effectively avoiding interference from underground power lines and metal facilities to ensure stable signal transmission.
