Bulan Pipes and Tubes stands out as a leading manufacturer and supplier of SA178 Tubes, proudly based in Jakarta, Indonesia. These tubes, whether seamless or welded, are crafted from carbon steel and are specifically designed for use in boilers and superheaters, particularly in high-pressure and high-temperature settings. They meet ASME standards and find their place in thermal power plants, refineries, and heat recovery systems. Bulan is dedicated to precise manufacturing, ensuring dimensional accuracy and dependable mechanical performance. With a strong focus on quality, compliance, and timely delivery, Bulan caters to the power and process industries throughout Indonesia, providing robust and durable SA178 boiler tubes that excel in demanding thermal conditions.
SA178 Tubes are generally made up of carbon (up to 0.27%), manganese (0.93–1.06%), phosphorus (≤0.035%), and sulfur (≤0.035%). These carbon steel tubes are recognized for their impressive strength, ductility, and weldability. They boast a minimum tensile strength of 415 MPa, a yield strength of 255 MPa, and an elongation of 30%, depending on the grade (A, C, or D). After welding, SA178 tubes undergo heat treatment to restore their mechanical integrity and eliminate internal stresses, ensuring they perform reliably in high-temperature steam and pressure environments, such as boilers and heat exchangers.
