What is BS EN 12451 - Seamless, round tubes for heat exchangers about?
BS EN 12451 is a European standard on copper and copper alloys that discusses the best procedures and specifications required for manufacturing high-quality seamless, round tubes for heat exchangers.
BS EN 12451 specifies the composition, property requirements, and tolerances on dimensions and forms for seamless round drawn copper and copper alloy tubes for heat exchangers, condensers, evaporators, and desalination equipment. It applies to copper and copper alloy tubes supplied in the size range from 6 mm up to and including 76 mm outside diameter and from 0,5 mm up to and including 3 mm wall thickness. The sampling procedures and the methods of testing for verification of conformity to the requirements of BS EN 12451 are also specified.
Who is BS EN 12451 - Seamless, round tubes for heat exchangers for?
BS EN 12451 on seamless, round tubes for heat exchangers is relevant to:
- Manufacturer of seamless round drawn copper and copper alloy tubes
- Manufacturer of heat exchangers, condensers, evaporators, and desalination equipment
Why should you use BS EN 12451 - Seamless, round tubes for heat exchangers?
Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper. BS EN 12451 provides guidance on designations, material composition, mechanical properties, dimensions and tolerances, surface quality, mechanical tests, stress corrosion resistance tests, test methods, declaration of conformity, and inspection documentation.
As a user of BS EN 12451, you can be ensured of the technological requirements of seamless, round copper capillary tubes. With obedience and compliance to BS EN 12451, you can efficiently manufacture high-quality seamless, round copper tubes for heat exchangers. With BS EN 12451 you can be ensured that the products consistently meet and exceed quality assurance targets. BS EN 12451 exemplifies the required material composition, mechanical properties that help you achieve precision in terms of product functionality and specification. BS EN 12451 provides you with comprehensive information useful throughout the process of production.
What’s changed since the last update?
BS EN 12451:2012 supersedes BS EN 12451:1999 which is withdrawn. In comparison with EN 12451:1999, the following significant technical changes were made:
- For Cu-DHP (CW024A):
- The material condition R220 in Table 2 was added
- Elongation values were modified for R250 and R29
