Based in Delhi, India, Ojas Pipes and Tubes is a reputable producer and supplier of premium marine-grade stainless steel pipes. Our pipes, which are renowned for their durability and precision engineering, are made especially to resist the severe conditions found in maritime environments. We provide durable and corrosion-resistant stainless steel solutions that meet both national and international standards thanks to our strong dedication to quality and innovation. Customers looking for high-end marine-grade piping solutions in sectors like shipbuilding, offshore oil and gas, desalination plants and other coastal engineering projects choose Ojas Pipes and Tubes.
Iron, chromium (16–18%), nickel (10–14%), and molybdenum (2–3%) make up the majority of marine grade stainless steel pipes, which are usually made from grades like 316 and 316L. Molybdenum improves corrosion resistance, particularly against saltwater and chlorides. These pipes have good elongation (up to 40%), a yield strength of 205 MPa, and a tensile strength of about 515 MPa. For demanding marine and coastal applications where performance and durability are crucial, they are perfect because they maintain their strength and integrity in the face of high pressure and extreme temperatures.

Applications needing high mechanical strength and corrosion resistance frequently use marine grade stainless steel pipes. They are used in shipbuilding, seawater piping, exhaust lines, ballast systems, and structural elements in the maritime sector. These pipes are also perfect for dockside facilities, desalination plants, and offshore oil rigs where there is continuous exposure to humidity and saltwater. Because of their hygienic qualities, they are used in pharmaceutical facilities, food and beverage systems, and chemical processing plants in addition to marine environments. Long-term dependability in challenging environmental circumstances is guaranteed by their resistance to pitting, crevice corrosion, and stress corrosion cracking.
