Known for its dedication to excellence and innovation, Bulan Pipes and Tubes provides outstanding piping solutions that cater to a wide range of industrial needs. The company focuses on Duplex Steel S31803, a premium material celebrated for its remarkable strength and resistance to corrosion. With a strong distribution network and a customer-centric approach, Bulan Pipes and Tubes guarantees timely deliveries and dependable service across various sectors, including oil and gas, petrochemical, and marine industries.
The composition of Duplex Steel S31803 pipes includes primarily chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), along with manganese and nitrogen. This unique blend significantly boosts both corrosion resistance and strength. On the mechanical side, these pipes boast a tensile strength of about 620 MPa and a yield strength of roughly 450 MPa, along with impressive elongation and impact toughness. Their dual-phase microstructure, which combines austenite and ferrite, provides exceptional fatigue resistance and stress corrosion cracking resistance, making them perfect for high-pressure and corrosive environments where standard stainless steels might not hold up.
