As of the third quarter of 2025, the global seamless steel pipe market exhibited a price trend of moderate increase with regional differentiation. Key factors driving price fluctuations included: rising raw material costs, increased energy costs, increased oil and gas investment, the recovery of global infrastructure projects, and the impact of geopolitics on logistics.
API series seamless steel pipes and structural seamless steel pipes:
950 – 1150 USD/ton
Reasons for the increase:
Recovery of US oil and gas activity (increased number of shale gas drilling rigs)
Continued demand driven by European energy structure adjustments
Recovery in manufacturing PMI + increased local labor costs
Prices for oil casing pipes and line pipes generally rose due to the continued expansion of oil and gas exploration projects:
Some API 5CT and API 5L high-grade products: ≥ 1200 USD/ton
Prices fluctuated less due to the release of new local production capacity:
Structural pipes and medium- and low-pressure fluid pipes:
850 – 980 USD/ton
The following are typical specification FOB price ranges (2025 Q3) for international procurement reference.
Different countries, modes of transportation, packaging, and certification requirements may cause some fluctuations.

Fluctuations in iron ore, scrap steel, and coke directly impact production costs;
Stainless steel is most affected by nickel prices: 316L > 304;
Higher material grades result in higher costs.
Typical Price Difference:
316L seamless pipes are 3–4 times more expensive than carbon steel.
The production of seamless steel pipes requires specialized equipment and technologies, including hot rolling, cold drawing, and heat treatment, etc.
Hot-rolled seamless steel pipes: Low cost, moderate precision, lowest price.
Cold-drawn seamless steel pipes: High precision, smooth surface, 10%–30% more expensive.
Heat-treated (normalizing, tempering) seamless steel pipes: Improved mechanical properties, 30–80 USD/ton more expensive.
Ultrasonic testing, hydrostatic testing: Meets high standards, 20–60 USD/ton more expensive.
Outer diameter (OD), wall thickness, and length directly affect cost.
Increased OD increases cost.
A 100% increase in wall thickness increases cost by almost 90–110%.
Custom lengths require additional processing fees.
High-grade steels and those meeting stringent standards (e.g., API 5L, ASTM A335, EN 10216) require more rigorous quality control and additional testing, including ultrasonic testing, hydrostatic testing, and certification.
These quality assurance steps increase costs but are crucial for demanding applications such as oil and gas pipelines or high-pressure boilers.
Many seamless steel pipes undergo surface treatments such as galvanizing, anti-corrosion coatings, or specialized paints to extend their service life.
Depending on the coating method and thickness, these treatments can increase the cost per ton of steel pipe by $100 to $500.
Black Painting: +10–25 USD/ton
3LPE/3LPP Anti-corrosion Coating: +80–150 USD/ton
Zipper: +120–500 USD/ton (varies with zinc prices)
Bulk orders typically enjoy volume discounts because fixed setup costs and processing time can be spread over larger quantities.
Conversely, small or urgent orders may incur additional costs due to increased labor, setup, and expedited shipping expenses.
The origin of the steel pipe also affects costs. Pipes from countries with lower labor and energy costs (such as China, India, and Turkey) generally have lower upfront prices.
However, international shipping costs, customs duties, and longer delivery times may offset these savings, depending on your location.
Seamless steel pipes are typically 30% to 100% more expensive than welded steel pipes, depending on the material grade and application.
Yes.
This is because its manufacturing process is more complex, quality standards are higher, material selection is more stringent, and more waste is generated during production.
ASTM A106 Grade B: $1,800-$2,300 per ton
API 5L Grade B: $1,900-$2,400 per ton
API 5L X52-X70: $4,500-$9,000 per ton
