Bulan Pipes and Tubes, based in Jakarta, Indonesia, has earned a solid reputation as a reliable manufacturer and supplier of high-quality Alloy Steel Welded Pipes. These pipes are celebrated for their remarkable strength, durability, and performance, especially in high-temperature and high-pressure settings. Crafted from top-notch alloy steel and utilizing advanced welding techniques, they meet international standards like ASTM and ASME. With a diverse selection of sizes, thicknesses, and grades, Bulan’s alloy steel welded pipes find their way into power plants, refineries, petrochemical facilities, and industrial boilers. Committed to quality, reliability, and customer satisfaction, Bulan consistently provides dependable pipe solutions.
Alloy Steel Welded Pipes are made up of various alloying elements, including chromium (0.50–9%), molybdenum (0.20–1%), carbon (0.10–0.30%), and occasionally nickel, vanadium, and manganese, depending on the specific grade (like P11, P22, or P91). These elements significantly enhance the mechanical properties, resulting in tensile strengths ranging from 415 to 860 MPa and yield strengths from 205 to 585 MPa. The welded alloy steel pipes are known for their excellent heat resistance, hardness, and ability to withstand pressure. Rigorous post-weld heat treatment and thorough inspections guarantee their structural integrity and long-lasting reliability in critical service conditions.
