Seamless Steel Pipe Price List

As of 2026, 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.

Global Seamless Steel Pipe Market Price Trends

1. North America and Europe (Significant Increase)

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

2. Middle East and South America (Strong Demand for High-Pressure Energy Pipes)

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

3. Southeast Asia and India (Relatively Stable Prices)

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

Notes:
1. Prices above are ex-factory prices, including tax. A small delivery fee will be charged upon customer pickup. Shipping costs are not included.
2. The selection of domestic and international materials (grades) is based on publicly available data, choosing products with the closest specifications, but complete consistency of materials (grades) is not guaranteed.
3. The weights of the products in the table are the results of weighing at the time of the actual transaction.
4. Other commonly used materials include: Q235B/Gr.D/ss400, Q345/Gr.50/S335JO, 20Cr/ASTM 5120/SCr420, 40Cr/ASTM 5140/SCr440, etc.

Factors Affecting the Cost of Seamless Steel Pipes

1. Raw Material Costs

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.

2. Manufacturing Processes and Equipment

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.

3. Seamless Steel Pipe Sizes

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.

4. Material Grades and Quality Standards

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.

5. Surface Treatment and Coating

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)

6. Order Quantity and Delivery Time

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.

7. Logistics and Origin

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.

FAQ

1. How much more expensive are seamless steel pipes than welded steel pipes?

Seamless steel pipes are typically 30% to 100% more expensive than welded steel pipes, depending on the material grade and application.

2. Is seamless pipe more expensive?

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.
