Frequently Asked Questions About Protective Pipe
What are the benefits of using protective pipe instead of direct burial?
Protective pipe provides several advantages over direct burial: It shields cables and pipes from mechanical damage, moisture, and chemical exposure; allows for easier maintenance and future upgrades; reduces installation costs by eliminating the need for deep trenches; and provides better protection against ground movement and environmental stresses.
How do I select the right protective pipe diameter?
When selecting protective pipe diameter, consider these factors: the outer diameter of the cable or pipe being protected, space needed for future additions (recommend at least 25% extra space), bend radius requirements, and installation method. For multiple cables, use the "fill ratio" calculation (total cable cross-section should not exceed 40% of pipe area). Our technical team can help with specific sizing recommendations.
What is the expected lifespan of your protective pipe?
Our protective pipe has an expected service life of 50+ years when properly installed. The HDPE material resists corrosion, chemicals, and abrasion. UV-stabilized versions maintain integrity when exposed to sunlight. Actual lifespan depends on installation quality, environmental conditions, and operational stresses. We provide a 10-year warranty against material defects.
Installation Guidelines
- Prepare trench with proper bedding material (minimum 100mm thick)
- Ensure continuous slope (minimum 1%) for drainage applications
- Use proper joining techniques (butt fusion, electrofusion, or mechanical couplings)
- Backfill carefully with suitable material in layers
- Compact backfill progressively to avoid pipe deformation
- Mark pipe location with warning tape or tracer wire
