- Longevity: 30-50+ years of life and less maintenance.
Installation Guide
- Site Assessment & Trench Design: Decide on the plan for alignment, depth, and cable capacity.
- Excavation: Get rid of the dirt and rocks to form a level trench base.
- Bedding Preparation: Put sand or fine soil as a cushion for the duct.
- Laying Duct Sections: Take great care in aligning the sections to keep the slope and straightness.
- Jointing: Go for either solvent weld or mechanical couplers to make connections that are secure.
- Cable Pulling: Put in cables with the help of lubricants so that there would be no friction damage.
- Backfilling: Do it in layers to both secure ducts and protect cables.
- Warning Tape Installation: Install above ducts to warn future diggers.
Accessories & Fittings
Solvent Weld & Mechanical Couplers – Ensure leak-proof and strong joints.
Elbows (45° & 90°) – For smooth directional changes.
Pulling Eyelets – Facilitate cable insertion.
Warning Tapes – Alert for future excavation.
Spacer Clips & Support Saddles – Maintain alignment and spacing.
Performance in Harsh Conditions
- Heat of the desert, great soil compaction, and lots of surface load do not affect it.
- Salty coastal soils and the presence of chemicals are not a threat to it.
- The fiber optic and telecom lines keep their integrity during long pulls because of the smooth interior.
Maintenance & Inspection
Periodic inspections for joints, fittings, and warning tapes.
Minimal maintenance required due to high durability of PVC.
Maintain as-built records for future network expansions or repairs.
