Dang Steel, based in Da Nang, Vietnam, has built a solid reputation as a manufacturer and supplier of Carbon Steel SAW (Submerged Arc Welded) Pipes. They cater to essential infrastructure and energy sectors both in Vietnam and around the globe. With state-of-the-art manufacturing facilities and a strong focus on quality, Dang Steel produces SAW pipes that comply with international standards like API 5L, ASTM A252, and ISO 3183. These pipes are celebrated for their impressive strength, wide diameter range, and outstanding weld integrity, making them perfect for high-pressure applications. Dang Steel is committed to timely delivery, competitive pricing, and reliable service for critical pipeline and structural projects.
Carbon Steel SAW Pipes are generally made from low-carbon or medium-carbon steel grades, containing 0.20–0.30% carbon, 1.0–1.5% manganese, along with trace amounts of silicon, phosphorus, and sulfur. These pipes boast high mechanical strength, with yield strengths ranging from 245 to 485 MPa and tensile strengths between 415 to 760 MPa, depending on the specific grade and standards (like API 5L X42 to X70). The submerged arc welding technique guarantees a high-quality weld with excellent penetration and minimal defects. Dang Steel offers SAW pipes in both LSAW and SSAW forms, suitable for a variety of industrial applications.
