Sudarshan Single Wall Corrugated (SWC) Pipes are essential HDPE sheathing ducts used in the post-tensioning of tendons within pre-stressed concrete structures. These pipes offer significant advantages in projects like metro pillars, railway bridges, high-rise buildings, flyovers, offshore platforms, viaducts, and underpasses. With superior corrosion resistance compared to traditional metallic ducts, SWC pipes enhance the longevity and durability of critical infrastructure. They also provide excellent compression strength, impact resistance, and ease of installation with continuous length coils, ensuring efficient and cost-effective construction. Sudarshan SWC Pipes are trusted across various projects in India for their proven performance in safeguarding pre-stressed concrete structures.
