Underground Sewerage & Drainage Pipes

Finolex underground drainage & sewerage pipes are intended to carry soil and waste from building to sewers or drains and then to treatment plants or disposal points. Finolex underground drainage and sewerage pipes are recommended for buildings where hygiene is a prerequisite such as hospital, hotels, school etc. They can also be used for rainwater collection and disposal. Finolex sewerage pipes are specially designed for underground - non pressure applications like gravity drainage, sewer flow and transportation of soil & waste discharge.

Finolex underground drainage and sewerage pipes are an ideal replacement of CI and DI piping systems because they are lightweight, corrosion free and long lasting. These pipes are 100% water tight, which makes them free from ingress and seepage of water, thus ensuring hygiene.

Finolex brings its trademark quality and precision stamp to its sewerage pipes to assure consumers of the best sanitary experience, by promising superior strength and durability. Our stringent quality assurance approach across all stages of manufacturing gives the product a high degree of reliability, which makes Finolex underground drainage and sewerage pipes a preferred choice of leading MEP consultants, architects, builders, plumbing contractors, plumbers and quality conscious people across the country.

These pipes are available in sizes 110, 160, 200, 250 and 315 mm in stiffness classes of SN-2, SN-4 & SN-8 and conform to IS 15328. Sewerage pipes come with selfit and ringfit sockets in a standard length of 3 & 6 meters. Selfit pipes are self-socketed and can be joined with the help of solvent cement; while Ringfit pipes need no threading or solvents for jointing and can withstand high pressures. Sewerage ringfit pipes are made with EPDM rubber rings that are long lasting and can withstand high pressures. For ease of jointing and to ensure better insertion, the use of Finolex rubber lubricant is recommended.

FAQ

Finolex ASTM Pipes can safely be used for plumbing applications including potable or drinking water. Finolex ASTM pipes are manufactured by using high grade Finolex PVC resin and unique compounding which is lead free. Thus, it is safe for potable water supply and more so,because of pvc material with smooth inner surface,there is  no scaling or deposition. It is  Corrosion-free and chemical resistant. It is tough & durable and immune to fungus, bacteria,algae formation.

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

Finolex offers ASTM range from ½” to 8” dia pipes,in  Schedule 40 and 80 series. For more information refer to the Finolex ASTM Pipes and Fittings Brochure.

Finolex sewerage Pipes are available in sizes 110, 160, 200, 250, and 315 mm in stiffness classes of SN-2, SN-4 & SN-8. 110,160,200 mm dia pipes are available in selfit socket type , whereas 250 and 315 mm dia pipes are available in ringfit socket type. For more information Contact Us.

Finolex Sewerage Pipes are meant for Non-pressurised applications. However, it can withstand “external earth pressure “ and has STIFFNESS CLASS 2 KN/m² for SN2, STIFFNESS CLASS 4 KN/m² for SN4 and STIFFNESS CLASS 8 KN/m² for SN8.

Equivalent SDR series of Finolex sewerage pipes are- 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) .

Finolex SN 8 (SDR 34, STIFFNESS CLASS 8 KN/m²) has the highest stiffness and can withstand more external earth pressure as compared to SN4 and SN2.

SDR ( Standard dimension Ratio) of sewerage pipe of any particular size is calculated by dividing OD ( Outside diameter ) of the pipe in mm by its WT (wall thickness) in mm.

Finolex underground drainage and sewerage pipes are recommended for drainage and sewerage applications including buildings where hygiene is a prerequisite like hospitals, hotels, schools, and building complexes.
