Vipul Pipes and Tubes, Chennai, India, is a reliable manufacturer and supplier of Marine Grade Stainless Steel Pipes with corrosion-resistant solutions specifically designed for extreme marine and coastal conditions. With a strong focus on quality, innovation, and international compliance, the company provides long-lasting and high-performance piping systems appropriate for a variety of marine and offshore applications. Their Marine Grade Stainless Steel Pipes are recognized for their outstanding resistance to saltwater, mechanical stress, and harsh temperatures, making them the most sought-after selection across shipbuilding, naval engineering, oil & gas, and desalination projects in India as well as overseas.
Marine Grade Stainless Steel Pipes, usually constructed with grades such as 316, 316L, or duplex stainless steels, exhibit far better resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. These contain a high percentage of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), which further strengthens their anti-corrosive properties. Their mechanical properties consist of tensile strength of approximately 515–620 MPa, yield strength of 205–310 MPa, and very good elongation (30–40%). These tubes deliver high performance when subjected to pressure and temperature fluctuations and are also commonly found in welded, seamless, or ERW configurations for versatility.

Marine Grade Stainless Steel Pipes find extensive applications in the shipbuilding industry, offshore oil drilling platforms, and coastal structural facilities because of their high corrosion resistance in seawater environments. The pipes are crucial for seawater cooling systems, ballast systems, exhaust lines, and bilge lines, as well as marine HVAC systems. In the oil & gas industry, they find application in subsea pipelines and chemical transport lines. Moreover, these pipes are used in desalination plants, sewage treatment, and wet processing industries. Their mechanical strength and sea-element resistance make them essential for long-term and low-maintenance installations in highly corrosive and challenging environments.
