Maria Pipes and Tubes is a reliable producer and supplier of Marine Grade Stainless Steel Pipes from Kuala Lumpur, Malaysia. With a reputation for accuracy in manufacture and compliance with international standards of quality, the company supplies corrosion-resistant stainless steel piping systems specifically tailored for aggressive marine conditions. The pipes are designed to endure perpetual exposure to seawater, humidity, and temperatures, which makes them perfect for use in offshore applications, shipbuilding, and coastal infrastructure. Based on strength, performance, and on-time delivery, Maria Pipes and Tubes caters to both local and international customers in the marine, oil & gas, and defense industries.
Marine Grade Stainless Steel Pipes are usually constructed from alloys like 316 and 316L, having a high proportion of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%). This composition also gives superb resistance to corrosion, particularly pitting corrosion and crevice corrosion due to saltwater and chlorides. These pipes have excellent mechanical properties, such as good tensile strength, ductility, and toughness even at low temperatures. Its capacity to resist oxidation, scaling, and rust in wet or submerged conditions makes it suitable for long-term operation in marine environments. 316L, with its reduced carbon content, provides enhanced weldability and corrosion resistance.
