PVC pipe InstalPlast 160×500 mm SN4 — drainage/sewer pipe

PVC pipe InstalPlast 160×500 mm SN4 is a rigid, orange-brown sewer and drainage pipe intended for underground, non-pressurized wastewater and stormwater systems. Made of unplasticized PVC-U, the pipe is suitable for conveying effluents with pH 2–12 at temperatures up to +40°C (short-term up to +60°C). The smooth internal surface reduces scale and deposits; the pipe is manufactured for buried installations such as trenches, road embankments, culverts and other utility engineering works. Each 500 mm pipe section has a socket with a silicone-sealed gasket and a simple connection system for tight, trouble-free assembly.

Advantages

The InstalPlast 160×500 mm SN4 pipe offers high mechanical strength and impact resistance due to PVC-U construction, chemical resistance across a wide pH range, and a smooth internal surface that limits fouling. Its SN4 stiffness class provides adequate resistance to typical external loads in buried applications while keeping the product lightweight for easier handling and installation. The silicone-sealed socket connection ensures a tight, quick and reliable joint.

Suitable for

• Buried gravity sewer and drainage lines
• Trench installations under roads or beside roadways
• Culverts and passageways through embankments
• Underground utility routing for residential and commercial sites

How to use

Prepare the trench or bedding according to applicable installation standards and local regulations. Place pipe sections end-to-end, ensuring the silicone-sealed gasket in the socket is clean and properly seated to form a watertight connection. Align and tamp surrounding backfill material carefully to maintain pipe alignment and avoid point loads. Observe recommended cover depths and loading conditions for SN4 stiffness class when planning road or embankment crossings.

Usage recommendations

Inspect gaskets before assembly, keep pipe ends free of dirt and debris, and follow local standards for trenching, bedding and backfill compaction. Avoid prolonged exposure to temperatures above the specified limits and prevent concentrated external loads beyond SN4 capacity.
