Manufacturer, Supplier & Exporter of External Epoxy Coated Pipes
External Epoxy Coated Pipes (EEC Pipes) are specialized carbon steel pipes coated externally with high-performance epoxy resin to provide superior corrosion resistance, durability, and long service life. Manufactured by Riddhi Siddhi Impex, these pipes are widely used in industries where underground, submerged, or exposed pipelines require strong protection against corrosion, chemical exposure, and moisture penetration...
The manufacturing process of EEC pipes involves cleaning the steel surface thoroughly, applying a fusion-bonded epoxy (FBE) or liquid epoxy coating on the external surface, and curing it at high temperatures. This ensures strong adhesion of the coating to the steel substrate, preventing rust, pitting, and external damage caused by environmental factors or soil conditions..
Riddhi Siddhi Impex, a trusted name in the Indian steel pipe industry, offers these pipes in seamless, welded (ERW, LSAW), and spiral welded formats. The company caters to a wide range of pipe diameters, wall thicknesses, and lengths according to project requirements, ensuring compatibility with international standards such as ASTM, API, ISO, EN, and DIN..
Externally coated epoxy pipes find extensive applications in oil and gas transportation, water supply systems, petrochemical plants, sewage pipelines, and industrial fluid transfer networks. The external epoxy coating provides excellent resistance against acidic, alkaline, and saline environments, making these pipes suitable for both underground and above-ground installations...
The pipes are available across major domestic cities including Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru (Mysore), Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Narmada, Ankleshwar, Navsari, Valsad, Rajpipla.
