Seamless Steel Pipe
HIGH QUALITY PRODUCTS
Seamless Steel Pipe
Seamless Steel Pipes are hollow cylindrical tubes made from solid steel billets or ingots without any welding or seams. They are produced through a process called hot or cold drawing, where the steel is heated or cooled to the desired temperature and then formed into a seamless tube using various shaping methods. Seamless pipes offer uniformity in composition and structure, ensuring high-quality and reliable performance.
