  • Galvanized Cold-Rolled Seamless Steel Pipe

    Galvanized Cold-Rolled Seamless Steel Pipe

    Xinlida's China Galvanized Cold-Rolled Seamless Steel Pipe is a seamless steel pipe produced by the cold-rolling process. Compared with hot-rolled steel pipes, the cold-rolling process endows it with higher precision and better surface quality. The wall thickness of its pipes is uniform and the dimensional accuracy is high. Generally, the outer diameter tolerance is controlled within ±0.1mm, and the wall thickness tolerance is about ±0.05mm. It can meet the demands of high-precision processing. Meanwhile, the surface of cold-rolled seamless steel pipes is smooth, which reduces the resistance of fluid flow in the pipeline and improves the transportation efficiency. They are widely used in industries such as petroleum, natural gas, chemical engineering, boilers, and mechanical manufacturing.
  • Longitudinal Welded Pipe
