Ratnadeep Steel & Engg. Co. is one of the leading manufacturers, suppliers, and exporters of Carbon Steel Seamless and ERW Pipes & Tubes in India. We offer a complete range of carbon steel pipes in various sizes, thicknesses, and specifications to meet the diverse needs of our clients across industries. All our products are manufactured using superior-grade raw materials and advanced production technology to ensure excellent quality, strength, and performance. Carbon Steel Seamless Pipes are produced from solid round billets, which are heated and then pierced to form a hollow tube structure. This process results in a uniform, joint-free pipe that offers excellent pressure resistance and durability—ideal for high-temperature and high-pressure applications. ERW (Electric Resistance Welded) Pipes, on the other hand, are manufactured by rolling metal sheets and welding them longitudinally across their length. This creates a visible weld seam, distinguishing them from seamless pipes. We manufacture and supply carbon steel pipes that comply with multiple international standards such as ASTM A106 Grade B, ASTM A53 Grade B, ASTM A333 Grade 6, ASTM A671, ASTM A672, and other equivalent specifications. These pipes are available in both welded and seamless forms and are produced using Plug Mill and CPE (Cross Roll Piercing and Elongation) technologies for precise dimensional accuracy and superior surface finish. At Ratnadeep Steel & Engg. Co., we ensure that every pipe undergoes rigorous quality testing, including hardness, chemical composition, hydrostatic, and dimensional tests, to guarantee compliance with the highest standards. Our products are carefully packed in wooden boxes, hexagonal bundles, steel crates, or custom packaging to ensure safe delivery worldwide.
