The domestic macro-economic landscape has recently seen a surge in the issuance of special and local bonds, while international geopolitical tensions have driven oil prices and commodity sentiment higher. Despite these tailwinds, the seamless pipe market is currently exhibiting a "strong cost floor, slow price ascent" characteristic. While prices for rebar and hot-rolled coils have surged, the national average for 108*4.5mm seamless pipes stood at 4,248 RMB/ton as of March 22, a modest monthly increase of 33 RMB/ton. This report analyzes whether this rally can be sustained through the lens of raw materials, supply-demand dynamics, and downstream consumption.
As the primary raw material—accounting for over 70% of production costs—pipe billet prices dictate the absolute floor for seamless pipe quotes.
Regional Divergence & Convergence: Throughout March, the billet market showed a "North-South divergence" that eventually stabilized. As of March 22, Shandong 20# hot-rolled billets were quoted at 3,230–3,290 RMB/ton (up 50–100 RMB MoM), while Jiangsu billets reached 3,510–3,570 RMB/ton (up 30–50 RMB MoM). The regional price gap narrowed from 250 RMB to a more rational 170 RMB/ton.
Tight Supply: Environmental restrictions in Northern China have limited billet supply. Concurrently, rising operating rates at pipe mills have increased procurement demand, leaving major billet producers with full order books and low inventories, further cementing high costs.
Upstream Pressure: Fluctuations in overseas iron ore shipments and tight coke supply have raised blast furnace ironmaking costs. This "cost-push" effect leaves mills with little room or willingness to offer discounts, effectively capping any potential price downside.
Pipe mills significantly accelerated their production rhythm in March, despite localized environmental setbacks.
Operational Surge: The operating rate of 30 surveyed mills jumped from 56.92% in February to 80.06% by late March. Weekly output reached 399,200 tons, with capacity utilization hitting 79.21%.
Inventory Pivot: While mill-side stocks initially accumulated to 785,200 tons due to rapid production releases, social inventory growth has narrowed significantly.
Future Outlook: Current production levels are approaching a ceiling. As downstream demand continues to recover, the market is expected to shift into a "destocking channel" where mill inventory transfers more rapidly to social warehouses and terminal projects, creating conditions for further price firming.
Demand across the four core sectors—infrastructure, machinery, oil & gas, and pipe networks—is showing a steady "warm-up."
Infrastructure: The "15th Five-Year Plan" kick-off has accelerated special bond issuance. Major projects involving underground networks and high-speed rail have resumed, boosting demand for structural and low-pressure boiler tubes.
Machinery & Manufacturing: Equipment renewal policies are driving orders in the engineering machinery and pressure vessel sectors, leading to a MoM increase in alloy and high-pressure boiler tube procurement.
Oil & Gas: Rising international oil prices have stimulated domestic exploration and investment. Large-scale national trunk line projects are directly pulling demand for specialized seamless pipes.
Municipal Renovation: Underground pipe network renovations now account for over 20% of urban construction investment, providing a rigid demand base for gas and heating pipes.
Market Transactions: Daily transaction volume in March averaged 16,542 tons, a 4.42% WoW increase. Sentiment among traders is shifting from "cautious observation" to "cautious optimism."
The seamless pipe market is currently balanced between strong support and gradual recovery.
The Verdict: The rally has a solid foundation to continue, but a "sudden surge" is unlikely. We expect prices to fluctuate within a narrow, upward-biased range.
Price Target: The mainstream 108*4.5mm specification is expected to fluctuate between 4,200–4,300 RMB/ton.
Market Phase: We remain in a "Strong Expectation, Weak Reality" transition. While the "Golden March and Silver April" peak is deepening, the lack of concentrated, large-scale terminal procurement prevents aggressive price hikes.
Key Indicators to Watch: Watch for billet price trends, mill inventory drawdown speeds, and actual daily transaction fulfillment to judge the rally's longevity.
