Dadex Nikasi upvc pipe 75mm

Dadex Nikasi uPVC 75mm pipes are straight pipes designed for soil, waste, drain, sewer, and ventilation (SWV) systems, available with solvent weld or rubber ring push-fit (pressure-type) socket ends for jointing.

Product Description

These pipes belong to the Dadex Nikasi SWV range, made from un plasticized PVC (uPVC) for non-corrosive, lightweight drainage applications. They feature smooth interiors for low flow resistance and self-cleansing properties, resisting chemicals, sewer gases, and organic growth like algae or fungi. Standard lengths are 3m or 4m, ideal for building drains, stacks, and vents.

Specifications Dadex Nikasi upvc pipe 75mm

• Nominal size: 75mm outside diameter (OD), wall thickness typically 2.0–2.3mm depending on stiffness class (SN4–SN8 for gravity drainage).

• Standards: ISO 3633:2002(E)/EN 1329:1999 and PS 3214:1992 (Pakistan standard); rubber rings to PS 1915/ISO 4633.

• Joint options: One end socketed (solvent or push-fit), other plain spigot; full range matches fittings like elbows, wyes, and sockets.

• Performance: Self-extinguishing, electrically non-conductive, suitable for gravity flow up to 0.3–1 m/s velocity.

Solvent Joint Pipes

Usage: Preferred for rigid, permanent above-ground installations like vertical soil stacks or horizontal waste pipes where no movement is expected.
Jointing: Apply Dadex uPVC solvent cement to clean, chamfered spigot and socket; push together with 1/4 turn, hold 20–30s, cure 24h before testing. Ensures leak-proof, monolithic bonds.
Applications: Internal building drainage from sinks, showers, or floor traps to main lines.​

Push-Fit Pressure Pipes

Usage: Suited for underground sewers, drains, or lines with potential settlement/movement; “pressure” refers to elastomeric seal handling minor surges or deflection.
Jointing: Insert lubricated rubber ring into socket groove, push spigot to depth mark (no twist); quick assembly, testable immediately.​
Applications: External drains, sewer connections, or vent pipes where flexibility aids installation.

Key Applications

Common in residential/commercial buildings for 75mm branch lines: waste from basins/kitchens, vent pipes, or sub-mains feeding 110mm stacks. Solvent for fixed indoor runs; push-fit for buried or adjustable setups. For Karachi projects, they pair well with 110/160mm Nikasi mains per PS 3214.
