1. Standard Overview and Current Status
EN 10255 is a European standard, officially titled "Non-Alloy steel tubes suitable for welding and threading — Technical delivery conditions." This standard primarily specifies the technical requirements for round non-alloy steel tubes used for welded and threaded connections.
2. Scope of Application
The scope of application of the EN 10255 standard is clearly defined, mainly encompassing the following dimensions:
Applicable Products: Applicable to non-alloy steel tubes with circular cross-sections.
Manufacturing Process: The steel tubes must be suitable for both welded and threaded connections. This means that the chemical composition and mechanical properties of the material must support these two common connection methods without damage.
Size Range:
Outer Diameter: 10.2 mm to 165.1 mm.
Thread Size: Corresponding to 1/8 inch to 6 inches.
Series: Divided into two series: Medium and Heavy, providing three specified wall thickness types.
Applicable scenarios: According to the notes in the standard, steel pipes manufactured in accordance with this standard can be used for conveying fluids (such as water pipes, gas pipes, and compressed air pipes) as well as for other general engineering purposes.
