| Production Step | Description |
| Raw Material Inspection | High-quality carbon steel coils are inspected to ensure chemical composition and mechanical properties meet ASTM A53 requirements. |
| Coil Slitting | Steel coils are cut into suitable widths according to the required pipe size. |
| Forming Process | The steel strip is gradually formed into a round pipe shape through forming rollers. |
| ERW Welding | The pipe edges are welded together using Electric Resistance Welding technology to create a strong and uniform weld seam. |
| Heat Treatment & Sizing | The welded pipe is processed through sizing rollers to achieve accurate dimensions and improve stability. |
| Cutting & End Finishing | Pipes are cut into specified lengths, with ends processed as plain, beveled, or threaded according to customer requirements. |
| Surface Treatment | Pipes are finished with black coating, oiling, galvanizing, or customized surface protection. |
| Quality Inspection | Finished pipes undergo dimensional checks, mechanical tests, and weld inspections before shipment. |
| Packing & Delivery | Qualified pipes are bundled, labeled, and prepared for safe transportation to global destinations. |
