Price of Seamless Carbon Steel Pipes & Price List for Duplex Plates

October 19, 2023 0


In the world of construction, manufacturing, and various industrial applications, the choice of materials plays a pivotal role. Two such materials that are essential for many projects are seamless carbon steel pipes and duplex plates. These components are widely used in industries like oil and gas, petrochemical, water treatment, and more. In this blog, we will explore the factors that influence the price of seamless carbon steel pipes and provide a Price List Duplex Plates for duplex plates to help you make informed decisions for your projects.

Understanding Seamless Carbon Steel Pipes

Seamless carbon steel pipes are an integral part of various industrial processes. They are known for their durability, corrosion resistance, and high tensile strength. These pipes are often used in high-pressure applications, conveying gases and liquids, and are vital in the construction of pipelines for transporting oil, gas, and water. The price of seamless carbon steel pipes can vary significantly based on several factors:

  1. Steel Grade: The type of carbon steel used greatly impacts the price. Different grades offer varying levels of strength and corrosion resistance, with higher grades usually commanding a higher price.
  2. Size and Dimensions: The diameter and wall thickness of the pipes influence the cost. Larger and thicker pipes generally cost more due to the increased material required.
  3. Production Standards: Pipes produced in compliance with specific international standards, such as ASTM, DIN, or JIS, may have different price points based on the quality and performance they offer.
  4. Coating and Finishing: Coatings, such as galvanization or epoxy, can affect the price. These coatings enhance corrosion resistance and durability but add to the overall cost.
  5. Market Conditions: The overall demand and supply in the steel industry, as well as factors like international trade policies and tariffs, can cause fluctuations in prices.

Duplex Plates: An Overview

Duplex plates are another essential material in various industries, known for their outstanding combination of strength and corrosion resistance. Duplex stainless steel is a two-phase material, consisting of an equal mix of austenitic and ferritic microstructures, which contributes to their remarkable properties. When choosing duplex plates, it’s essential to consider factors that influence their price:

  1. Grade: Similar to seamless carbon steel pipes, the grade of duplex stainless steel significantly affects the price. Higher-grade duplex plates offer better corrosion resistance and higher strength but are often more expensive.
  2. Thickness: The thickness of the plates plays a crucial role in determining their cost. Thicker plates require more material and often come at a higher price.
  3. Size: Larger plates, both in terms of length and width, are more expensive due to the increased raw material consumption.
  4. Finish and Surface Treatment: The finish and surface treatment, such as polishing or coating, can add to the cost of duplex plates. These treatments enhance aesthetics and corrosion resistance.

Price List for Duplex Plates

While the exact prices for duplex plates can fluctuate based on the factors mentioned above, here’s a general price list to provide you with a ballpark figure:

  1. Grade 2205 Duplex Plate (4mm thickness): $8 – $12 per kilogram
  2. Grade 2507 Super Duplex Plate (6mm thickness): $12 – $18 per kilogram
  3. Grade 2304 Duplex Plate (8mm thickness): $6 – $10 per kilogram

Please note that these are approximate prices, and they can vary depending on your location, supplier, and specific project requirements.


Seamless carbon steel pipes and duplex plates are fundamental components in many industries, offering strength, durability, and corrosion resistance. When considering these materials for your projects, it’s crucial to understand the factors that influence their prices, such as steel grade, size, and market conditions. By being informed about these variables, you can make well-informed decisions that align with your project’s requirements and budget.
