Manufacturer, Supplier & Exporter of Epoxy + PU Dual Layer Coated Pipes
Riddhi Siddhi Impex is a renowned manufacturer, exporter, and domestic supplier of Epoxy + PU Dual Layer Coated Pipes in India. These pipes are designed to deliver exceptional corrosion resistance, mechanical protection, and long-term durability in harsh environmental conditions. The dual coating system combines the strength of an Epoxy base layer with the flexibility and UV resistance of a Polyurethane (PU) topcoat, making it a perfect choice for both underground and above-ground applications in industrial and infrastructure projects.
The Epoxy + PU Dual Layer Coated Carbon Steel Pipes offered by Riddhi Siddhi Impex are manufactured using high-quality raw materials that conform to international standards such as ASTM, API, DIN, and ISO. The inner epoxy coating ensures a smooth surface that minimizes frictional losses and prevents corrosion from water or chemicals. The outer polyurethane coating provides excellent weather resistance, abrasion protection, and impact strength, ensuring reliable performance even in highly corrosive or marine environments..
These dual-layer coated pipes are widely used in industries such as oil and gas, petrochemical, water treatment, marine engineering, and power generation. The epoxy inner coating resists corrosion from transported fluids, while the PU outer layer protects against environmental elements, including moisture, UV radiation, and mechanical wear. This makes them highly suitable for buried, submerged, or exposed pipeline systems, especially where long-term reliability and maintenance-free performance are critical..
Riddhi Siddhi Impex ensures precision in every stage of production—from surface preparation and coating application to curing and final inspection. The epoxy layer is typically applied using fusion bonded or liquid epoxy coating techniques, followed by a polyurethane layer that enhances impact resistance and flexibility. This dual-layer combination results in an advanced coating system that adheres strongly to the pipe surface and provides long-lasting protection even under extreme temperatures and pressures..
The company offers Epoxy + PU Dual Layer Coated Pipes in various grades, including ASTM A106, A53, and API 5L (Grades B, X42, X52, X60, and X65). Pipes are available in sizes ranging from ½” NB to 120” NB, with thicknesses varying from Sch 20 to Sch 160 and XXS, depending on project requirements. Riddhi Siddhi Impex also provides customized coating thicknesses, pipe lengths, and end types—Plain End (PE), Beveled End (BE), or Threaded—to suit diverse applications across different sectors..
