Stainless Steel 347 and 347H Electropolished Pipes Manufacturer, Supplier and Exporter in Indonesia, Jakarta

Bulan Pipes and Tubes is a reputable manufacturer and supplier located in Jakarta, Indonesia. They specialize in high-quality Stainless Steel 347 and 347H Electropolished Pipes, designed to offer exceptional corrosion resistance, smooth hygienic surfaces, and reliable performance at high temperatures. These pipes are crafted according to ASTM A312 and ASTM A358 standards and feature stabilized austenitic stainless steels with niobium to prevent carbide precipitation during both welding and service. The electropolishing process results in an ultra-smooth, chromium-rich surface that minimizes product contamination and enhances cleanability. Available in various sizes, schedules, and finishes, these pipes find extensive use in pharmaceuticals, food processing, chemical plants, and high-purity applications that demand top-notch surface quality.

Stainless Steel 347 and 347H Electropolished Pipes are composed of approximately 17–20% chromium, 9–13% nickel, and niobium for stabilization. The 347H grade features a higher carbon content (around 0.04–0.10%) to boost high-temperature creep strength. Their tensile strength typically falls between 515–750 MPa, while yield strength is about 205 MPa. The electropolishing process effectively removes surface impurities, lowers micro-roughness, and enhances corrosion resistance, especially in chloride and acidic environments. The bright, passivated finish not only improves cleanability but also reduces bacterial adhesion, making these pipes perfect for applications that require outstanding purity and long-lasting corrosion protection.
