Introducing the Kaczmarek - KAN ZEW (GŁADKA) SN2 series, a reliable choice for external sewerage projects. These PVC pipes are built to handle outdoor drainage and wastewater transport with ease. The smooth inner wall promotes fast flow, while the foamed multilayer core keeps the pipes lightweight and easy to handle on site. Rated SN2, they provide solid stiffness to resist soil pressure and surface loads without bending.

Why Multilayer PVC Works Better

The KAN ZEW design uses a three-layer multilayer structure. Solid PVC forms the outer and inner walls for durability and smooth water movement. The middle layer is foamed PVC, which cuts down on weight and adds thermal insulation to help prevent freezing. This construction makes the pipes easier to carry, position, and backfill, saving you labor time and reducing material fatigue during long trench runs.

Quick Sealing with K-U21 LOCK Rings

Every pipe comes pre-fitted with a K-U21 LOCK rubber sealing ring. This gasket creates a tight, watertight joint that blocks roots and stops groundwater from entering the line. The LOCK design clicks into place quickly, so you do not need extra sealants or special tools. Installers get a consistent, leak-free connection every time, which speeds up the job and cuts down on future call-backs.

Flexible Lengths for Any Layout

To match your trench planning, the series is available in 1000 mm, 2000 mm, and 3000 mm lengths. All options share a 200 mm diameter and a 3.9 mm wall thickness. This range lets you choose the right run length to minimize joints, adapt to different site conditions, and keep your material inventory simple. Whether you are laying a short residential line or a long commercial drain, you will find the exact size you need.

Built to Last in Tough Conditions

External sewerage lines face moisture, soil shifts, and chemical exposure. The KAN ZEW SN2 pipes resist corrosion, abrasion, and ground movement, keeping their shape for decades. When installed with proper bedding and compaction, they deliver a stable, maintenance-free drainage system. Trust Kaczmarek for a pipe that handles the job today and protects your investment for years to come.
