Manufacturer, Supplier & Exporter of Asphalt Coated Pipes
Riddhi Siddhi Impex is a leading manufacturer and supplier of high-quality steel pipes in India, specializing in coated pipes such as asphalt coated pipes. With a strong focus on corrosion protection and durability, the company caters to a wide range of industries including water supply, oil and gas, sewage systems, and infrastructure projects. Their expertise ensures that every pipe meets rigorous quality standards and project specifications..
Asphalt coated pipes are carbon steel pipes with an outer protective layer of asphalt, designed to prevent corrosion when buried underground or exposed to soil, moisture, and other aggressive environments. This coating acts as a barrier between the steel surface and corrosive elements, significantly enhancing the service life of pipelines. These pipes are particularly useful in underground installations where long-term durability is critical..
Riddhi Siddhi Impex offers asphalt coated pipes in various sizes, wall thicknesses, and lengths to suit diverse project requirements. The pipes can be supplied in seamless, ERW, or welded forms depending on the application. Their coating thickness is carefully applied to ensure uniform coverage and maximum protection against environmental factors, maintaining the integrity of the steel pipe over years of operation..
The company supplies asphalt coated pipes across India, covering major cities such as Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru, Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Ankleshwar, Navsari, Valsad, and Rajpipla. This widespread availability ensures timely delivery to urban and regional centers alike..
One of the key advantages of Riddhi Siddhi’s asphalt coated pipes is their high resistance to soil corrosion, moisture ingress, and mechanical wear during handling and installation. The asphalt coating is tough yet flexible, preventing cracking or peeling, which is crucial for long-term reliability. This makes them an ideal choice for pipelines transporting water, oil, gas, or industrial fluids over long distances..
