Sintex InfraFlex pipes are used for water supply, irrigation systems, antural gas distribution, and industrial fluid transportation. They’re ideal for both underground and overground installations where durability and flexibility are essential.

"High flexibility for easy handling and laying Corrosion and chemical resistance 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.
