EN545 Ductile Iron Pipe

Designed Specifically for Drinking Water NetworksEN545 is the European standard for ductile iron water pipes. These pipes bring clean drinking water to homes, factories, and farms. The standard covers everything from raw water intake to distribution mains. Every requirement protects water quality.Cement Mortar Lining Keeps Water CleanWe line every pipe with Portland cement mortar. This lining prevents rust from contacting the water. It also creates a smooth surface. Water flows easily. Bacteria cannot grow on cement mortar. Your water stays fresh from the treatment plant to the tap.

Raw Water Intake Lines – From rivers, lakes, or reservoirs to treatment plants. EN545 handles the pressure and external load.

Water Treatment Plant Piping – Inside the plant for settled water, filtered water, and backwash lines. Smooth lining maintains water quality.

Transmission Mains – Large diameter pipes moving water from treatment plants to storage tanks. High pressure capability for long distances.

Distribution Networks – Medium diameter pipes bringing water to neighborhoods and industrial areas. Flexible joints handle ground movement.

Service Connections – Small diameter pipes connecting buildings to the main. Flanged options available for meter connections.

Ductile iron itself resists corrosion better than steel. But buried pipes need extra protection. EN545 provides a multi-layer system.Layer 1: Cement Mortar Lining (Inside)Portland cement mortar does three jobs. First, it prevents water from contacting the iron. No contact means no rust inside the pipe. Second, it creates a smooth surface for high flow. Third, the cement keeps the water pH stable.Layer 2: Zinc Coating (Outside)We spray 200 g/m² of zinc onto the pipe exterior. Zinc corrodes before iron does. This is cathodic protection. Even if the bitumen coating gets scratched, zinc protects the pipe. EN545 does not require zinc. But we include it as standard because it adds decades of life.

Tyton Push-On Joint (Standard for Most Projects)

The spigot pushes into the socket. A rubber gasket creates the seal. No bolts, no welding, no special tools. One worker can install a joint in 2-3 minutes. Deflection up to 5 degrees. Perfect for long water mains.

Restrained Joint (For High Pressure and Changes in Direction)Water pressure tries to push joints apart. At bends and tees, the force is strong. Restrained joints lock the spigot into the socket. No concrete thrust blocks are needed. Saves time and material.

The melted iron is then processed and poured into the casting process. During the casting process, it is necessary to ensure that the molten iron flows evenly into the casting pipe mold and control the cooling speed to avoid cracks or deformation of the cast pipe.
