Liam Pipes and Tubes is a well-respected manufacturer and supplier of Marine Grade Stainless Steel Pipes, proudly based in Houston, USA. They specialize in providing corrosion-resistant piping solutions that are tailor-made for the tough conditions found in marine and coastal environments. These pipes are crafted from top-notch stainless steel grades like 316, 316L, or duplex alloys, ensuring they can stand up to saltwater, humidity, and harsh chemicals. Liam Pipes and Tubes offers a variety of marine grade pipes in different sizes, wall thicknesses, and surface finishes, all while adhering to ASTM and ASME standards. Their products are commonly utilized in shipbuilding, offshore platforms, desalination plants, and marine infrastructure, guaranteeing long-lasting performance and reliability.
Marine Grade Stainless Steel Pipes are generally constructed from stainless steel 316 or 316L, which contains about 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. The inclusion of molybdenum significantly boosts resistance to pitting and crevice corrosion in environments rich in chloride. These pipes boast impressive mechanical properties, with tensile strength ranging from 515 to 620 MPa and yield strength close to 205 MPa, along with excellent ductility and impact resistance. The low carbon variant (316L) is particularly advantageous for welding, as it minimizes the risk of sensitization, making it ideal for welded structures that will face marine conditions.
