DN 1200/1800 Large Diameter Spiral Steel Pipe

Release Tme: 2024-02-29

DN 1200/1800 large diameter spiral steel pipe refers to a large diameter spiral steel pipe with a nominal diameter (DN) of 1200 mm or 1800 mm. This kind of steel pipe is usually used to transport fluids, such as water, oil, natural gas, etc., especially in projects that require large flow transportation.

The manufacturing of large-diameter spiral steel pipes usually uses the spiral submerged arc welding process, that is, after the steel plate is curled into a tube shape, it is welded through a spiral weld. This process can produce larger-diameter steel pipes with high-quality welds and stable and reliable overall performance of the steel pipes.

DN 1200/1800 large diameter spiral steel pipe has good mechanical properties, corrosion resistance and durability, and can adapt to various harsh environmental conditions and usage scenarios. In the fields of oil, natural gas, water conservancy, electricity and other fields, this kind of steel pipe is widely used in transmission pipelines, bridges, highways, construction and other projects.
