Finolex provides sewerage and underground drainage pipes that meet IS 15328 standards. These pipes are designed for gravity drainage, sewer flow, and transporting soil and waste discharge. They're ideal for carrying soil and waste from buildings to sewers, drains, treatment plants, disposal points, and septic tanks.

The Finolex Sewerage Pipes are specially designed for underground - non-pressure applications like gravity drainage, sewer flow and transportation of soil and waste discharge.

Our sewerage pipes are available with selfit and ringfit sockets, in standard lengths of 3 and 6 metres. The Selfit pipes feature self-sockets and are joined using solvent cements, while ringfit pipes come with EPDM rubber rings and are joined using lubricants.

Finolex offers sewerage pipes in various sizes: 110, 160, 200, 250, and 315 mm, with stiffness classes SN-2, SN-4, and SN-8. Pipes with diameters of 110, 160, and 200 mm come with selfit sockets, while those with diameters of 250 and 315 mm feature ringfit sockets.

The Finolex Sewerage Pipes are designed for non-pressurised applications. Despite this, they can endure "external earth pressure" and have stiffness ratings of 2 KN/m² for SN2, 4 KN/m² for SN4, and 8 KN/m² for SN8.
 

The Finolex Sewerage Pipes have equivalent SDR series: SN 2 (SDR 51, stiffness class 2 KN/m²), SN 4 (SDR 41, stiffness class 4 KN/m²), and SN 8 (SDR 34, stiffness class 8 KN/m²).

The SDR series indicates the standard dimension ratio of our sewerage pipes, providing a standardised measurement for their dimensions and properties.

The Finolex Underground Drainage and Sewerage Pipes are suitable for various applications, especially in buildings where hygiene is crucial, such as hospitals, hotels, schools, and building complexes.

PVC is chosen for sewerage pipes due to its exceptional durability, resistance to corrosion, and cost-effectiveness, making it an ideal material for long-lasting sewerage systems.

Our PVC sewer drainage pipes boast a long lifespan, typically lasting for several decades with proper installation and maintenance, ensuring reliable performance and cost-effectiveness over time.
