How it was executed
The pipe-rack package was awarded to China Communications Materials Group; Youcheng supplied the pipes and fittings. A dedicated 30-person project team handled plate procurement, pipe forming, blasting, coating, inspection, welded bracing, packing and port booking, so procurement, production and coating ran in parallel instead of one after another.

Export packaging was the critical path
With more than ten sizes on a single contract, packaging decides the shipping date. Pipes and fittings were packed size by size into wooden cases, steel frames, U-racks and pallets, each marked to the shipping mark, so the site could receive and install straight from the container.

Why it matters for your project
DN3400 capability — proof the mill goes beyond the usual DN2000 ceiling for pipe-rack and large-diameter work.
Coating in-house — three-layer anti-corrosion applied in our own shop, no external coater and no schedule slip.
Port logistics — 240+ truckloads inside one window is a logistics result, not only a production one.
