PVC drainage pipe InstalPlast 160 mm x 3000 mm SN4

InstalPlast PVC drainage pipe 160 mm x 3000 mm, SN4 stiffness class, designed for subsurface drainage and stormwater conveyance. The pipe is made of rigid PVC-U material offering high strength, impact resistance and chemical durability. Its smooth orange-brown internal surface reduces encrustation and sediment buildup, and each pipe features a socket with a silicone-sealed gasket for secure, easy connections with compatible fittings.

Advantages

The InstalPlast PVC drainage pipe is lightweight yet robust, resistant to many chemicals and corrosion, and manufactured from unplasticized PVC-U for long service life. A smooth bore minimizes deposits and improves flow, while the silicone-sealed socket ensures a tight, watertight joint and straightforward installation. The product’s SN4 stiffness rating makes it suitable for typical subsurface installations under normal load conditions.

Suitable for

• Subsurface gravity drainage systems in trenches and fields
• Stormwater conveyance and site drainage for residential and commercial projects
• Installation under roads, embankments or bridge approaches (non-traffic-bearing or specified load conditions)
• Underground non-pressurized wastewater transport with pH 2–12 and temperatures up to +40°C (short-term up to +60°C)

How to use

Position pipes in a properly prepared trench with suitable bedding to ensure uniform support along the barrel. Connect pipes using the socket with the silicone-sealed gasket, ensuring the spigot is fully inserted and the sealing surface is clean. Follow project-specific slope and alignment requirements to maintain gravity flow. Backfill in layers and compact carefully to avoid point loads on the pipe. Use compatible fittings and accessories from the same system for reliable joints.

Usage recommendations

Do not use the pipe for pressurized applications. Avoid prolonged exposure to temperatures above +40°C. Verify load and bedding requirements for installations under roads or heavy loads and follow local installation standards and manufacturer instructions for jointing and handling.
