Manufacturer, Supplier & Exporter of Liquid Epoxy Coated Pipes

Liquid Epoxy Coated (LEC) Pipes are carbon steel or alloy steel pipes internally coated with a high-performance liquid epoxy layer. This protective lining prevents corrosion, reduces friction, and enhances the overall longevity of pipelines carrying water, chemicals, or hydrocarbons. LEC pipes are a combination of steel’s strength and epoxy’s chemical resistance, making them ideal for modern industrial and municipal applications..

The liquid epoxy layer ensures superior protection against aggressive media, minimizes scale buildup, and maintains smooth internal surfaces for better flow efficiency. These pipes offer low maintenance requirements, excellent durability, and resistance to both acidic and alkaline environments, making them suitable for long-term infrastructure projects..

Riddhi Siddhi Impex is a reputed Indian manufacturer and supplier of coated and uncoated steel pipes. With extensive experience in the steel industry, they specialize in producing and supplying LEC pipes that meet international quality standards. Their expertise ensures that clients receive high-quality pipes suitable for industrial and municipal projects..
