Benchmark Project: Dual-Track Workshop – 219–4220 mm Spiral Welded Pipe Production Line
2026-03-19
This is our latest benchmark project completed in China, featuring a state-of-the-art overall plan and equipped with two spiral welded pipe production lines that comprehensively cover a diameter range of 219–4,220 mm. The facility can reliably produce a full spectrum of spiral steel pipes meeting national standards, fully satisfying the diverse requirements of various engineering applications.
The project constructs its workshop to world-class standards, featuring a well‑planned layout and an excellent production environment. Comprehensive supporting facilities cover the entire process flow, including material feeding, forming, welding, inspection, end‑flattening, and hydrostatic testing. The fully integrated line operates with high efficiency and stability, boasting a high degree of automation, thereby providing robust assurance for customers to achieve continuous, high‑quality, and highly efficient production.
