ASME SA312 304 Stainless Steel Studded Tubes are specialized heat exchanger tubes designed for enhanced thermal performance in high-temperature and high-pressure environments. These tubes are manufactured according to the ASME SA312 standard and are made from 304 stainless steel, a widely used material known for its excellent corrosion resistance, durability, and strength.
Key Features:
Material Composition: 304 stainless steel is an austenitic alloy composed primarily of chromium (18-20%) and nickel (8-10.5%) with a low carbon content. This composition provides excellent corrosion resistance, particularly against oxidation and chemical exposure.
Studded Design: The studded tubes are equipped with welded studs or protrusions on their surface, which significantly enhance the heat transfer efficiency. The studs increase the surface area, allowing for better heat dissipation in applications like boilers, heat exchangers, and furnaces.
Manufacturing Standards: These tubes conform to the ASME SA312 specification, ensuring high-quality manufacturing processes, precise dimensional tolerances, and reliable material performance.
High-Temperature Resistance: 304 stainless steel studded tubes are suitable for applications involving temperatures up to 870°C (1600°F), making them ideal for heat-intensive processes.
Corrosion Resistance: The chromium content in 304 stainless steel offers excellent resistance to rust, pitting, and other forms of corrosion, even in harsh industrial environments.
