DIN and EN Standards: DIN and EN standards are established by organizations in Europe to regulate the manufacturing and performance of various products, including pipes. DIN standards are primarily used in Germany, while EN standards are European-wide standards developed by the European Committee for Standardization (CEN).

Classification: DIN and EN standards classify pipes based on their material, dimensions, and specific applications. These standards cover a wide range of pipe types, including steel pipes, plastic pipes, copper pipes, and more.

Material Specifications: DIN/EN series pipes specify the materials used in their construction. For example, DIN 2440 covers steel pipes suitable for conveying gas and oil, while EN 12201 regulates polyethylene pipes for water supply.

Dimensions: These standards provide precise measurements and tolerances for various pipe sizes and shapes. This ensures that pipes are manufactured consistently and can be easily interconnected with other components.

Performance and Testing: DIN/EN series pipes also outline performance criteria and testing procedures. They may include tests for pressure resistance, leakage, corrosion resistance, and other important properties to ensure the pipes meet quality and safety standards.

Interchangeability: Standardization through DIN/EN series pipes ensures that products from different manufacturers can be interchanged easily, promoting compatibility and reducing the risk of compatibility issues during installation and maintenance.

Safety: Compliance with DIN/EN standards helps ensure the safety of pipes and the systems they are used in. This is especially important in critical applications such as transporting hazardous materials.

DIN/EN series pipes are integral to various industries, providing standardized specifications for pipes in terms of material, dimensions, performance, and safety. These standards facilitate efficient manufacturing, installation, and maintenance of pipelines, contributing to the reliability and safety of infrastructure and industrial processes across Europe and beyond.

Seamless Pipes and Tubes for Pressure Applications

The EN 10216 Euronorm replaces the old DIN 17175 and 1629 standards. This standard is designed for pipes used in pressure applications, such as a pipeline. This is why the associated steel qualities are designated by the letter P for 'Pressure'. The value that follows this letter designates the minimum yield strength. The subsequent letter designations provide additional information.

The EN 10216 comprises several parts. The parts that are relevant to us are as follows:

Some examples:

Normalized is defined as: normalized (warm) rolled or standard annealing (at a min temperature of 930°C). This applies to allqualities designated by the letter 'N' in the new Euro Standards.
