What is the EN 10255 standard?

The EN 10255 standard is a technical specification that sets out the requirements for the production, testing, and certification of steel tubes for applications in gas, water, and other pressure purposes. It is widely recognized and used throughout Europe as a benchmark for ensuring the quality and safety of these types of tubes.

Background and Scope

The EN 10255 standard was first published in 1995 by the European Committee for Standardization (CEN), with a revised version released in 2004. It supersedes the older national standards of European countries, harmonizing the requirements and facilitating trade between different member states. The standard covers both seamless and welded steel tubes, with various options for surface finishes.

Technical Specifications

The EN 10255 standard specifies the dimensions, tolerances, mechanical properties, and testing procedures for these steel tubes. It provides guidelines for the chemical composition, which ensures the required strength and durability. The standard also includes additional requirements for threads, zinc coating, and marking of the tubes.

One of the critical aspects of this standard is the pressure testing of the tubes. They undergo rigorous hydraulic or non-destructive testing to ensure that they can withstand the intended working pressures without leakage or failure. This ensures the safety and reliability of the tubes during their lifespan.

Certification and Compliance

To meet the EN 10255 standard, manufacturers must have proper quality management systems in place to maintain consistent production and compliance. These systems are audited and certified by independent bodies, ensuring that the products conform to the specified requirements. The certification process involves regular inspections, test samples, and assessments of production processes.

The use of EN 10255-compliant tubes provides confidence to end-users, such as contractors, engineers, and project owners, that the products they are using meet high-quality standards. Compliance with this standard also facilitates international trade, as it ensures compatibility and interchangeability between different manufacturers and suppliers.

In conclusion, the EN 10255 standard plays a crucial role in ensuring the quality, safety, and compatibility of steel tubes used in gas, water, and pressure applications. Its widespread acceptance and adoption across Europe demonstrate its importance in maintaining reliable and efficient infrastructures. By adhering to this standard, manufacturers and end-users can trust in the performance and longevity of these essential components.
