Cooling tubes for piping

Round copper tubing specialised in refrigeration systems and ducting with an outer diameter of 3.18 to 108 mm.

Medidas:

Exterior Ø 3.18 to 108 mm.

Data sheet: Cooling tubes for piping

Copper tubes for air conditioning and refrigeration systems have good heat conduction and corrosion resistance properties, suitable for this type of application. In our catalogue you will find a wide range of sizes from 3.18 to 108 mm diameter with the corresponding nominal wall thickness. Various delivery options are available: in straight lengths or in coils for duct and equipment cooling. You can also use our weight calculator to determine the weight of the product by entering the material, format and type of product, as well as the dimensions to suit your needs.

In the technical data sheet section you will find details of the technical characteristics, measurements and tolerances on the external diameter and wall thickness. To guarantee a correct application, both the interior and exterior surfaces must be smooth, so that the coolant is properly distributed.

Bronmetal is ISO 9001:2015 certified, which guarantees the quality in the management of all processes with the objective of the wellbeing of our customers.

SURFACE QUALITY

The interior and exterior surfaces of the piping must be clean and smooth. Any residue left over after solvent has evaporated must not exceed 38 mg/m2 of the internal surface.
