Product Features
Socket and spigot design enables fast on-site assembly while maintaining consistent sealing performance under pressure fluctuations.
Manufactured strictly to ISO2531 and EN545 standards, suitable for potable water distribution, raw water transmission, and reclaimed water systems.
Internal cement mortar lining complies with ISO4179, while external zinc spraying plus bitumen coating provides long-term corrosion resistance for buried and underwater applications.
High-strength ductile iron grade (GGG40/GGG50) delivers superior elongation and impact resistance, accommodating ground settlement and pressure surges.
