    I was going to use it for a block-off plate on an engine, but it ended up using 8mm aluminum, instead, as it's easier to cut, shape, and drill, but this is quality SS, and I'll definitely use it on another project.

    It is what it is. What more can really be said? I've ordered two of these. Both arrived packaged very well. No warps, bends or scratches. Recommended!

Product Description

Product Description:

Product Overview: Carbon Steel Pipe

Carbon steel pipe is a type of metal pipe made from a combination of iron and carbon, with a low carbon content of 0.05%-0.25%. It is commonly used in various industries such as construction, oil and gas, and transportation due to its high strength and durability.

DIN Standards

Our carbon steel pipe is available in various DIN standards, including ST33, ST37, ST35.8, ST42, ST45-8, and ST52. These standards determine the chemical composition and mechanical properties of the pipe, ensuring its quality and suitability for different applications.

Length Options

We offer two options for the length of our carbon steel pipe - random length and fixed length. Random length pipes are cut to a range of lengths, typically between 5-7 meters, while fixed length pipes are cut to a specific length according to customer requirements.

Processing Services

Our carbon steel pipe can be processed in various ways to meet the specific needs of our customers. We offer cutting, bending, welding, and other services to customize the pipe to the desired shape and size.


Our carbon steel pipe has a tolerance level of ±6%, meaning that the actual dimensions of the pipe may vary by up to 6% from the specified dimensions. This ensures that our pipes meet the required standards and have a consistent quality.


Our carbon steel pipe complies with various international standards, including ASTM A106, ASTM A53, API 5L, EN10216, and DIN1629. These standards ensure that the pipe meets the necessary specifications for its intended use, such as pressure and temperature ratings.

With our high-quality carbon steel pipe and various processing services, we are committed to providing our customers with durable, reliable, and customized solutions for their piping needs. Contact us today for more information or to request a quote.
