Seamless pipe (SMLS pipe) price fluctuations are influenced by multiple factors, from raw materials to end-user demand. The following are the key factors influencing seamless pipe prices and their quantitative analysis:
Raw material cost is a key variable:
1. Steel price fluctuations: The primary raw materials for seamless pipes are carbon steel, alloy steel, and other materials, and their prices directly determine the cost of the finished pipe. For example, the average price of domestic 20# hot-rolled steel billets in 2023 was 3,800-4,200 yuan/ton (Source: Mysteel.com), accounting for over 60% of the total cost of seamless pipes. A 10% increase in steel prices typically translates to a 6%-8% increase in seamless pipe prices.
2. Additional costs due to alloying elements: Alloy steel pipes containing elements such as chromium and molybdenum (such as P91) are 30%-50% more expensive than ordinary carbon steel pipes due to material scarcity.
Production Process and Technical Requirements:
1. Differences between cold rolling and hot rolling: Cold-rolled (drawn) seamless pipes offer higher precision (tolerance ±0.1mm) and a smoother surface, but processing fees are 2,000-3,000 yuan/ton more expensive than hot-rolled pipes. Hot-rolled pipes are more suitable for large diameters (e.g., Φ426mm and above) requiring lower costs.
Market Supply and Demand and Industry Applications:
Policy and International Trade Factors:
Other Key Variables:
Seamless pipe prices are the result of the dynamic interaction of multiple factors, and buyers should make a comprehensive assessment based on real-time data and industry trends. For example, if iron ore prices exceed $150/ton in 2024 (currently $130), seamless pipe costs are expected to increase by another 10%-12%.
