Leak-proof joints using butt-fusion or electrofusion welding
UV and weather resistant
No scaling or rusting
Long service life even in harsh conditions"
They are joined using butt-fusion welding or electrofusion welding, both of which create strong, leak-proof, and durable connections.
Yes, they are highly resistant to chemicals, making them suitable for transporting industrial fluids including certain chemicals and waste.
Yes. Their flexibility and strength make them perfect for marshy areas, rocky soil, corrosive environments, and places with uneven terrain.
InfraFlex pipes are designed for long-term use, with a typical lifespan of 50 years or more, depending on usage and installation conditions.
No. The inner surface of these HDPE pipes is smooth and non-reactive, which does not support microbial growth, making them safe and hygienic for water transportation.
