What is Dadex Nikasi upvc pipe 110mm ?
Dadex Nikasi UPVC pipes are high-quality un plasticized polyvinyl chloride (UPVC) pipes from Dadex Eternit Limited (Pakistan), designed for pressure-rated drain, sewer, and ventilation (DSV) systems. The 110mm (4-inch) variant supports both solvent joint (solvent weld) and push-fit (rubber ring joint) connections, making it versatile for gravity and low-pressure applications. These pipes are solid-wall, single-layer extrusions with excellent hydraulic properties, corrosion resistance, and longevity.
They conform to BS EN 1329-1 (DSV), BS EN 1401-1 (pressure), ASTM D 3034, and ISO 4435 standards, with ISI certification for Pakistani markets. Ideal for underground sewerage, building drainage, and ventilation in residential, commercial, and industrial setups.

Detailed Description
-
Design Features:
- Smooth inner surface (Hazen-Williams C=150) for optimal flow (low friction, self-cleaning).
- Extruded with uniform thickness for high ring stiffness (SN8 rating: 8 kN/m² burial strength).
- Spigot end chamfered for easy jointing; socket with reinforcement rib for push-fit seal.
- Dual-joint system: Solvent for permanent, high-strength bonds; push-fit for fast, demountable installs.
- Resistant to soil chemicals, effluents, abrasion, and microbial growth.
-
Available Classes:
| Class | Type | Wall Thickness | Max Pressure | Stiffness (SN) | Application |
|---|---|---|---|---|---|
| S4 | DSV | 3.2 mm | 0.5 bar | 4–8 kN/m² | Gravity sewer/drain |
| S5 | DSV | 4.2 mm | 1.0 bar | 8–16 kN/m² | Deep burial sewer |
| PN6 | Pressure | 4.6 mm | 6 bar | N/A | Low-pressure drain |
| PN10 | Pressure | 5.3 mm | 10 bar | N/A | Pumped sewer/vent |
Usage and Applications
-
Primary Uses:
- Sewer & Drainage: Underground wastewater/storm water mains in housing, roads, and farms.
- Building Plumbing: Soil, waste, and vent pipes (SWV) in multi-story structures.
- Pressure Systems: Low-head pumping for sewage transfer or industrial effluents.
- Suitable for trenchless installation (e.g., HDD) and aggressive soils.
-
Installation Guidelines:
- Cutting/Prep: Use pipe cutter for square ends; deburr and clean.
- Solvent Weld Joint:
- Apply primer, then solvent cement (Dadex-approved).
- Insert spigot to full depth; rotate 1/4 turn; hold 30 sec.
- Cure: 15 min initial, 24 hrs full strength.
- Push-Fit (Rubber Ring) Joint:
- Insert lubricated ring into socket groove.
- Apply pipe lube to spigot/ring; push until stop mark aligns.
- No curing time; test immediately.
- Laying: Bed in sand/gravel (150 mm min.); backfill in layers. Gradient: 1:40–1:80 for self-cleansing.
- Testing: Air test (0.5 bar/5 min) or water test (1.5x pressure/2 hrs).
- Supports: Every 1.5–2 m horizontally; anchor at bends.
- Tools: Hacksaw/cutter, lubricant, solvent kit.
-
Advantages:
- Lightweight (~1/8th concrete pipe weight) for manual handling.
- Watertight joints (leak rate <0.3 l/m/min).
- 50-year design life; maintenance-free.
- Cost savings: 30–40% vs. cast iron.
Accessories & Compatibility
- Pairs with Dadex Nikasi elbows, tees, bends (e.g., 110mm 87° branch).
- Use with solvent cement (e.g., Tangit or Dadex brand) and rubber rings (BS EN 681-1).
