Liam Pipes and Tubes stands out as a top-notch manufacturer and supplier of Stainless Steel 317 and 317L Instrumentation Tubing, proudly based in Houston, USA. They’ve built a solid reputation for providing high-quality, corrosion-resistant tubing solutions that meet the demands of critical industries where precision and durability are non-negotiable. Their 317/317L instrumentation tubing is crafted using cutting-edge techniques and adheres to strict international standards. With remarkable chemical compatibility, impressive strength, and outstanding pitting resistance, these tubes are perfect for complex instrumentation systems in sectors like petrochemical, pharmaceutical, food processing, and marine engineering, both in the USA and around the world.
The Stainless Steel 317 and 317L Instrumentation Tubing boasts a composition rich in chromium (18–20%) and nickel (11–15%), with an added touch of molybdenum (3–4%) to enhance corrosion resistance, especially in acidic and chloride-heavy environments. The “L” grade is designed with a lower carbon content (max 0.03%), which helps minimize the risk of sensitization during welding. These alloys deliver a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, and an excellent elongation rate of around 35–40%. Such mechanical properties make them ideal for high-precision, high-pressure, and high-corrosion instrumentation applications.
