Stainless Steel 304 / 304L Instrumentation Tubes are high-quality tubing solutions widely used in industries that demand precision, reliability, and resistance to corrosion. These tubes are specifically designed to meet the requirements of instrumentation systems where accurate measurement, control, and monitoring of fluids and gases are essential.
Grade 304 and 304L are part of the austenitic stainless steel family. SS 304 is composed primarily of chromium (18–20%) and nickel (8–10.5%), which provide excellent corrosion resistance and strength. SS 304L is the low-carbon version of 304, offering improved weldability and reduced risk of carbide precipitation during welding, which can otherwise lead to intergranular corrosion.
Both 304 and 304L grades exhibit strong resistance to a wide range of corrosive environments, including atmospheric conditions, oxidizing agents, and mild chemicals. This makes them ideal for applications in harsh environments such as offshore oil platforms, chemical processing plants, and marine systems.
304 / 304L stainless steel instrumentation tubes are manufactured to tight tolerances, ensuring consistent outside diameter (OD), wall thickness, and roundness. This precision is vital for leak-free and vibration-resistant connections in instrumentation and control systems.

The tubes are typically supplied with a smooth, bright annealed surface finish that not only improves aesthetics but also ensures low friction and prevents contamination in fluid systems. Cleanliness is crucial in industries such as pharmaceuticals and food processing, where hygiene and product purity are essential.Instrumentation tubing is available in both seamless and welded variants. Seamless tubes offer superior strength and pressure ratings, making them ideal for high-pressure environments. Welded tubes, while slightly less robust, offer cost efficiency and are suitable for many medium-pressure applications.
