High-Quality EN12451 Copper and Copper Alloy Seamless Tubes for Heat Exchangers Supplier, Factory
Scope  - Applies to seamless tubes made of copper and copper alloys used in heat exchangers, condensers, and similar heat transfer applications.  - Covers tubes for general industrial use, including refrigeration, petrochemical, and power plants.
EN 12451 is the European standard specifying requirements for seamless round copper and copper alloy tubes intended for use in heat exchangers, condensers, and related equipment.
Which material is best for seawater applications?
Cupronickel alloys such as CW702R (90/10) and CW704R (70/30) are ideal for seawater and brine applications due to their superior corrosion and erosion resistance.
What are the mandatory inspection tests for these tubes?
Mandatory tests include dimensional inspection, visual examination for surface defects, tensile testing per batch, and material-dependent flattening or expansion tests.
Is CW020A (Cu-DHP) suitable for welding?
Yes, CW020A Phosphorus-Deoxidized Copper is preferred for welded heat exchangers because the phosphorus content provides good weldability and prevents embrittlement.
What dimensional tolerances should I expect?
Tolerances for the outer diameter typically range from ±0.1 mm to ±1%, while wall thickness usually carries a ±10% tolerance, depending on the specific size and standard requirements.
Can I request specific certification for my order?
Yes, an Inspection Certificate 3.1 according to EN 10204 can be provided upon request to verify material quality and test results.
