Spiral pipes, also known as spiral steel pipes or spiral welded pipes, are manufactured by rolling low-carbon structural steel or low-alloy structural steel strips into a tubular blank at a specific helical angle—referred to as the forming angle—and then welding the seam. This process enables the production of large-diameter steel pipes from relatively narrow steel strips.

For liquid conveyance: water supply, drainage, wastewater treatment projects, slurry transport, and offshore water transport. For gas conveyance: coal gas, steam, and liquefied petroleum gas. For structural applications: pile‑driving casings, bridge construction, marine pile‑driving casings, as well as pipes used in wharves, roads, and building structures.
