BS 3059 Grade 360 Low Carbon Steel Tubes are commonly used in boiler, heat exchanger and high temperature applications because of their high strength, durability and resistance to pressure. These tubes are produced according to British Standards and provide high levels of mechanical properties, weldability and give high performance in harsh industrial environments like power plants, petrochemical plants, refineries, etc. They are balanced chemically to provide good formability and corrosion resistance and can be used for seamless and welded components. The USA Piping Solution offers a range of BS 3059 Grade 360 Tubes in multiple sizes, thicknesses, and specifications that are suitable for a wide variety of industrial applications. Each tube is thoroughly tested to guarantee dimensional precision, strength and extended service life at high temperatures and pressures.
