As a trusted supplier of EN10217 steel pipes, I am often asked about the common sizes of these pipes. EN10217 is a European standard that specifies the technical delivery conditions for welded steel tubes intended for pressure purposes. These pipes are widely used in various industries due to their high-quality and reliability. In this blog post, I will discuss the common sizes of EN10217 steel pipes, their applications, and why choosing the right size is crucial for your projects.
Understanding EN10217 Steel Pipes
EN10217 steel pipes are known for their excellent mechanical properties, including high tensile strength and good corrosion resistance. They are manufactured using different welding processes, such as submerged arc welding (SAW), which ensures a strong and durable weld. These pipes are suitable for transporting fluids and gases under pressure, making them ideal for applications in the oil and gas, petrochemical, and power generation industries.
Common Sizes of EN10217 Steel Pipes
The sizes of EN10217 steel pipes are typically specified by their outer diameter (OD) and wall thickness. The outer diameter can range from as small as 10.2 mm to as large as 2000 mm or more, depending on the application requirements. The wall thickness also varies, usually from 2.0 mm to 50 mm or greater.
Here are some of the most common size ranges for EN10217 steel pipes:
- Small Diameter Pipes: These pipes usually have an outer diameter ranging from 10.2 mm to 168.3 mm. They are commonly used in applications where space is limited, such as in plumbing systems, small-scale industrial installations, and instrumentation.
- Medium Diameter Pipes: With an outer diameter between 168.3 mm and 610 mm, medium diameter pipes are widely used in various industries. They are suitable for transporting water, oil, and gas in medium-sized pipelines, as well as in structural applications.
- Large Diameter Pipes: Pipes with an outer diameter greater than 610 mm are considered large diameter pipes. These pipes are often used in major infrastructure projects, such as long-distance pipelines, offshore platforms, and power plants. They can handle high-pressure and large-volume fluid or gas transportation.
In addition to the outer diameter and wall thickness, the length of EN10217 steel pipes can also vary. Standard lengths are typically 6 meters, 12 meters, or as per the customer's specific requirements.


Applications of Different Sizes
The choice of pipe size depends on the specific application and the requirements of the project. Here are some examples of how different sizes of EN10217 steel pipes are used:
- Small Diameter Pipes: In plumbing systems, small diameter pipes are used to distribute water to individual fixtures. They are also used in the manufacturing of heat exchangers, where their small size allows for efficient heat transfer.
- Medium Diameter Pipes: These pipes are commonly used in the oil and gas industry for transporting crude oil, natural gas, and refined products. They are also used in the construction of buildings and bridges for structural support.
- Large Diameter Pipes: Large diameter pipes are essential for major infrastructure projects. For example, in long-distance pipelines, they can transport large volumes of oil or gas over long distances. In offshore platforms, they are used for risers and flowlines to connect the subsea wells to the surface facilities.
Why Choosing the Right Size Matters
Selecting the appropriate size of EN10217 steel pipe is crucial for the success of your project. Here are some reasons why:
- Flow Capacity: The size of the pipe directly affects the flow capacity of the fluid or gas being transported. If the pipe is too small, it may restrict the flow, leading to reduced efficiency and potential operational problems. On the other hand, if the pipe is too large, it can result in unnecessary costs and increased energy consumption.
- Pressure Rating: The wall thickness of the pipe is related to its pressure rating. A pipe with a thicker wall can withstand higher pressures. Choosing the right wall thickness ensures that the pipe can safely handle the pressure requirements of the application.
- Structural Integrity: In structural applications, the size and strength of the pipe are important for maintaining the integrity of the structure. Using the correct size of pipe ensures that the structure can support the intended loads without failure.
