PVC pipe InstalPlast 160×1000 mm SN4 for drainage and sewer systems

InstalPlast PVC pipe 160×1000 mm SN4 is a rigid, orange-brown PVC-U pipe intended for gravity drainage and sewer systems. The pipe is made from unplasticized polyvinyl chloride (PVC-U), providing high strength, impact resistance and chemical resistance for transporting non-pressurized wastewater with pH 2–12 at temperatures up to +40°C (short-term up to +60°C). The smooth internal surface reduces scale and sediment build-up, and each pipe features a socket with a silicone-sealed ring for a simple, tight and trouble-free connection.

Advantages

The InstalPlast 160×1000 mm SN4 pipe offers durable mechanical performance under earth loads due to its SN4 stiffness class, a corrosion-resistant PVC-U construction, and a smooth bore that minimizes fouling. The integrated socket with silicone seal ensures a watertight joint and straightforward assembly steps, while the material resists many chemicals commonly encountered in drainage applications.

Suitable for

• Underground wastewater and sewer gravity lines
• Stormwater drainage systems and roadside drains
• Pipe runs under roads, embankments and culverts
• Other underground civil engineering drainage installations

How to use

Select appropriate trench depth and bedding according to local standards and the SN4 stiffness requirements. Insert the pipe with the socket oriented correctly, apply the silicone-sealed ring already fitted in the socket, and push the plain end into the socket until the joint is fully engaged. Ensure correct alignment and gradient for gravity flow. Backfill and compact surrounding material in layers as specified for underground drainage installations to achieve the required support and load distribution.

Usage recommendations

For durable performance, avoid prolonged exposure to temperatures above +40°C, inspect joints after assembly to confirm seals are fully seated, and follow local installation standards for trenching, bedding and backfilling. Use appropriate fittings and connections designed for PVC-U drainage systems.
