Brass instrumentation tubes are precision-engineered metallic tubes designed for use in industrial instrumentation and control applications. Manufactured primarily from copper-zinc alloys such as C26000 (Cartridge Brass) or C27000 (Yellow Brass), these tubes offer an excellent balance of mechanical strength, corrosion resistance, and ease of fabrication. Their superior performance in transmitting gases and fluids under controlled pressure and temperature makes them a preferred choice across multiple industries.
Brass, being an alloy of copper and zinc, exhibits favorable properties such as high thermal and electrical conductivity, good machinability, and resistance to dezincification in certain environments. These characteristics make brass tubes especially suitable for accurate and stable performance in sensitive instrumentation setups. Brass instrumentation tubes are typically manufactured in accordance with international standards such as ASTM B135, ASTM B43, EN 12449, and JIS H3300 to ensure quality, consistency, and safety.
These tubes are widely used in sectors such as oil & gas, petrochemical, chemical processing, power generation, shipbuilding, and HVAC systems. Common applications include hydraulic and pneumatic control lines, pressure gauge lines, cooling circuits, fuel and oil lines, and sensor connections. Their ability to maintain structural integrity under medium to low pressure and varying temperatures makes them ideal for complex and critical systems where precision and reliability are essential.
Brass instrumentation tubes offer numerous advantages, including corrosion resistance in non-aggressive environments, excellent ductility, and ease of installation. They can be easily bent, flared, soldered, or brazed without compromising strength, making them highly adaptable to different system designs. Additionally, the smooth internal surface minimizes friction and flow resistance, contributing to accurate and efficient fluid transfer. Their non-magnetic and spark-resistant nature also enhances safety in sensitive environments.
