Spiral-welded steel pipeis a durable piping solution manufactured by rolling steel plates into a spiral shape and welding the seams, designed for high-pressure, large-diameter fluid and gas transport. It is widely used in oil and gas pipelines, municipal water supply networks, sewage systems, and industrial process lines, where reliable performance under heavy loads and long-distance transport is essential.
A key advantage ofSpiral-welded steel pipelies in its structural efficiency and cost-effectiveness. The spiral welding process allows for larger diameters (up to 3000mm) and flexible length customization, reducing the number of joints needed for long pipelines. This design also distributes stress evenly across the pipe wall, enhancing its pressure-bearing capacity and resistance to external impacts, making it suitable for both underground burial and above-ground installations.
Spiral-welded steel pipefurther offers versatility and adaptability. It can be made from various steel grades (e.g., Q235, X70) to match different media—from water and natural gas to corrosive industrial fluids (when paired with coatings). Its smooth inner wall minimizes fluid friction, ensuring efficient transport, while the welded structure ensures leak tightness. Whether used in cross-country gas transmission or urban drainage projects, it delivers consistent performance across diverse engineering scenarios.
