Spirally Welded Steel Pipe

Tianjin Xinlida Steel Pipe Co., Ltd. has been focusing on producing all kinds of Spirally Welded Steel Pipe for many years.Different from the straight seam welding of straight seam welding pipe, our spiral welded pipe adopts double-sided submerged arc welding process, and the weld is spirally evenly distributed. This unique structure makes its ability to withstand internal pressure increase by 25% compared with straight seam welding pipe, especially suitable for harsh scenarios such as high pressure gas transmission and steam pipe network.The products cover a wide range of outer diameter 10-1200mm and wall thickness 1.5-20mm, from small diameter pipes in urban water supply and drainage systems to large diameter transmission pipes in petrochemical fields.

The production process is that after uncoiling, leveling and spiral forming, high frequency welding is formed to form welds, and some products need online heat treatment to improve weld toughness.Before delivery, each steel pipe shall pass the triple check points of hydrostatic test, ultrasonic flaw detection and size accuracy detection.Continuous forming welding, daily output up to hundreds of tons, more suitable for large-scale industrial production.Prices are also more competitive.

Why choose Xinlida?Not only because of reliable product strength and flexible specifications, but also because of cost-effective pricing, quality assurance of the whole process, and one-stop service from sample application to after-sales follow-up.Whether it is large-scale engineering procurement, or small batch customization needs, Xinlida can provide suitable spiral welded pipe solutions, there is a need to contact the consultation at any time.

Galvanized Oval Steel Pipe

Galvanized oval steel pipes use ordinary carbon structural steel or low-alloy structural steel round pipes as the base material. Through hot-dip galvanizing or electro-galvanizing processes, a uniform and dense zinc layer is formed on the inner and outer surfaces of the pipe. Its core function is to achieve long-term corrosion resistance through the sacrificial anode protection of the zinc layer, while also possessing basic properties such as pressure resistance, transportation, and support. Custom lengths are available, and further processing is possible. They are widely used in agricultural greenhouses and greenhouse frames!

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.
