  • Rust-proof spiral welded pipe

    Rust-proof spiral welded pipe

    Rust-proof spiral welded pipe is a type of pipe made from hot-rolled steel strip through a spiral forming process. Its core advantage lies in the special rust-proof treatment technology applied to its surface, which effectively resists the erosion of the pipe body by humid and corrosive environments. Tianjin Xinlida Steel Pipe Co., Ltd. has upgraded the traditional spiral welded pipe manufacturing process to an automated production line by introducing intelligent production equipment. While ensuring the uniformity of welding, the three processes of pretreatment, coating spraying, and curing and drying make the rust-proof layer bond more tightly to the pipe body, extending its service life by 3-5 times compared to ordinary welded pipes.
