| Detailed Introduction
Straight-seam steel pipe is a commonly used welded steel pipe whose weld runs parallel to the pipe’s longitudinal axis. It is manufactured by rolling and welding high‑quality carbon steel or low‑alloy steel, featuring a mature production process and stable performance. The product boasts uniform wall thickness, smooth and even welds, and high dimensional accuracy, with excellent overall toughness and compressive strength. It resists deformation and cracking and exhibits superior pressure resistance, corrosion resistance, and aging resistance. Throughout the manufacturing process, precision forming, automated welding, and nondestructive testing are employed to eliminate weld defects and ensure compliance with quality standards. With a full range of specifications and standardized dimensions, the product supports cut‑to‑length processing and custom non‑standard fabrication, offering easy installation and excellent sealing performance. It is widely used in municipal water supply and drainage, district heating, oil and gas transmission, steel structure projects, chemical equipment, bridge construction, and other fields, making it the preferred choice for medium‑ and low‑pressure fluid conveyance and structural applications.
