Product Description

LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for straight seam submerged arc welded steel pipe. Pipes produced by submerged arc welding and expanded diameter. LSAW steel pipe has a wide range of finished product specifications, and the weld has good toughness, plasticity, uniformity and compactness, and has the advantages of large pipe diameter, pipe wall thickness, high pressure resistance, low temperature resistance and strong corrosion resistance. In the construction of high-strength, high-quality long-distance oil and gas pipelines, most of the steel pipes required are large-diameter thick-walled straight seam submerged arc welded pipes. According to API standards, in large-scale oil and gas pipelines, when passing through Class 1 and Class 2 areas such as alpine regions, seabeds, and urban densely populated areas, LSAW pipe is the only designated applicable pipe type.
Main features of LSAW steel pipe:
1. The steel pipe has a longitudinal weld, and the inner and outer welds are welded by a submerged arc welding.
2. After the overall mechanical expansion treatment, the internal stress of the steel pipe is small and evenly distributed, which can effectively prevent stress corrosion cracking, and has high dimensional accuracy, which is convenient for on-site welding construction.
3. Using the pre-welding and fine-welding process, the welding process is stable and the welding seam quality is high.
4. The welding seam is easy to realize the non-destructive inspection in the production process and the non-destructive inspection in the field during the use process.
5. The product has a wide range of specifications, which can produce steel pipes with small diameter and large wall thickness as well as large diameter and large wall thickness.
