SWR Soil, Waste & Rainwater Pipes

Get Range Quote

SHRIJI SWR pipes are manufactured in Type A (rainwater and ventilation discharge) and Type B (soil and waste discharge). Available with push-fit rubber ring sockets (Ring-Fit) for thermal expansion accommodation and solvent socket (Selfit) options.

Key Engineering Advantages:

✓ Bacteria & Rodent Resistant: Smooth internal wall offers no hold for rodent gnawing or bacterial accumulation.
✓ Thermal Expansion Absorption: Integrated rubber ring groove accommodates seasonal pipe length variation without stress.
✓ UV Stabilized: Retains structural integrity in external vertical pipe duct runs exposed to intense solar radiation.

Sizes: 75mm, 90mm, 110mm, 160mmTypes: Type A (Thin Wall) & Type B (Thick Wall)Jointing: Ring-Fit (Rubber Gasket) / Selfit (Solvent)

A comprehensive ecosystem of precision injection-moulded fittings engineered for hydraulic optimization. Features inspection access door tees, bends, multi-floor reducing tees, and aeration vent cowls.

Key Engineering Advantages:

✓ Leak-Proof Inspection Doors: Threaded inspection caps allow quick rodding and maintenance without dismantling pipe stacks.
✓ Radius Flow Sweeps: Smooth internal radius bends minimize turbulence and splash clogs.
✓ High Impact Toughness: Will not crack during transit or rough on-site mechanical assembly.

Available Fittings: Door Bends, Plain Bends, Door Tees, Plain TeesReducers, Vent Cowls, Shoe Bends, Nahani Traps, P-TrapsSizes: 75mm to 160mm

Underground Drainage (UGD) & HDPE Sewerage Pipes

Get Range Quote

Specifically designed for buried non-pressure underground sewerage and stormwater lines. High ring stiffness enables these pipes to withstand dynamic traffic wheel loads, soil overburden, and ground settlement without ovalization.

Key Engineering Advantages:

✓ High Ring Stiffness: Certified in SN 4 and SN 8 stiffness classes for shallow or deep trench installations.
✓ Root Penetration Proof: Precision elastomeric seal prevents tree root ingress and subsequent line blockages.
✓ Complete Chemical Inertness: Unaffected by hydrogen sulfide gas (H2S) generation and acidic industrial effluents.

Sizes: 110mm, 160mm, 200mm, 250mm, 315mmStiffness Classes: SN 2, SN 4, SN 8Jointing: Integrated Elastomeric Rubber Ring Sockets

DWC Double-Wall Corrugated Sewerage Pipes

Get Range Quote

Double-wall structured piping with a corrugated exterior for exceptional mechanical strength and a mirror-smooth interior for rapid gravity waste flow. The modern, cost-effective replacement for traditional concrete and clay sewer lines.

Key Engineering Advantages:

✓ Lightweight & Easy Handling: 90% lighter than RCC pipes; requires no heavy cranes for trench placement.
✓ Superior Deflection Endurance: Absorbs ground tremors and vehicular vibrations without joint rupture.
✓ Zero Infiltration / Exfiltration: Protects underground water tables from environmental contamination.

Diameters: 75mm to 800mmStiffness: SN 4 & SN 8Standard Length: 6 Metre Straight Runs
