Pelican Underground LLC specializes in professional maintenance, repair, and restoration of cast iron pipes throughout Louisiana. Our team of skilled technicians understands the unique challenges that come with cast iron plumbing systems in both residential and commercial properties. Many older homes in Louisiana still have cast iron pipes that require regular maintenance to prevent costly issues and extend their lifespan.
Cast iron pipes were the standard for plumbing and sewer systems for decades, particularly in homes built before the 1970s. While durable, these pipes are susceptible to corrosion, scaling, and deterioration over time. Our cast iron pipe maintenance pros utilize advanced techniques and equipment to address these issues effectively, saving you from expensive emergency repairs and property damage.

Yes, traditional cast iron pipe is made predominantly of gray cast iron, which contains graphite in a flake form within its structure. According to industry standards like ASTM A74-21, these pipes must have a sound casting with a compact close grain structure. The material undergoes rigorous testing for tensile strength, breaking load, and chemical composition, including tests for phosphorus, sulfur, chromium, and other elements. Gray cast iron pipes typically have a tensile strength of around 18,000 psi. This material was chosen for plumbing applications because of its durability and resistance to pressure, though it is more brittle than modern alternatives like ductile iron, which contains graphite in a nodular or spheroidal form.
Yes, cast iron pipes have historically been used to transport water, sewage, and in some cases, gas. They were particularly common for sewage and drainage systems in buildings constructed before the 1970s, where their durability and sound-dampening qualities made them ideal. For water supply, cast iron pipes were often used in municipal water systems. However, for gas transportation, cast iron was eventually replaced by safer alternatives due to concerns about joint integrity and potential leaks. Today, while cast iron pipes remain in many older systems, modern plumbing codes typically specify different materials for new installations of water, gas, and sewage systems, with ductile iron, PVC, and copper being more common choices depending on the application.
Yes, for most modern applications, traditional cast iron pipe has been largely replaced by ductile iron pipe, which was introduced in 1955. Ductile iron offers significant advantages over gray cast iron, including higher tensile strength (60,000 psi compared to 18,000 psi), greater impact resistance (7 ft-lbs versus 2 ft-lbs), and superior pressure handling capabilities (150-350 psi). The key difference lies in the graphite structure – ductile iron features nodular or spheroidal graphite rather than the flake form found in gray cast iron. This structural difference makes ductile iron lighter, stronger, more durable, and less prone to cracking. While many older buildings and infrastructure still contain functioning cast iron pipes, virtually all new installations use ductile iron or other modern materials like PVC for their improved performance characteristics.
