On the other hand, EN pipe specifications also consider material toughness, impact resistance, and ductility, among other properties. This means EN pipe specifications are more comprehensive and detailed regarding material properties and suitability for different applications.

Manufacturing Process:

ASTM and EN pipe specifications also differ in the manufacturing process. ASTM pipe specifications apply to welded and seamless pipes, while EN pipe specifications are categorised into welded and seamless pipes. Seamless pipes are generally produced using hot-rolled or cold-drawn methods while welding metal sheets fabricate welded pipes. EN specifications also take into account the use of heat treatments for the production of certain types of pipes, which is not a requirement for ASTM pipe specifications.

Acceptance criteria:

The acceptance criteria for ASTM and EN pipe specifications also varies. ASTM pipe specifications are generally more stringent and require tighter tolerances, which means that pipes must be tested and validated to strict specifications to be considered up to standard. On the other hand, EN pipe specifications allow for greater tolerances, which means that pipes may be considered up to standard even if they do not meet all the specific requirements.

Design and Application:

Finally, ASTM and EN pipe specifications have different design and application considerations. ASTM pipe specifications are generally used in various industrial applications, including oil and gas, refineries, petrochemicals, and power generation. EN pipe specifications, however, are more suitable for high-pressure, high-temperature applications, such as those found in the chemical, pharmaceutical, and food and beverage industries.

Conclusion:

While both ASTM and EN pipe specifications have their strengths and suitable applications, it is essential to understand their differences to make an informed decision when choosing the right steel pipe for your project. ASTM pipe specifications are well suited for industrial applications, while EN pipe specifications are more comprehensive and detailed, focusing on high-pressure and high-temperature applications. Whichever standard you choose, understand your requirements and work with an experienced supplier to get the right materials for your project.
