Tubes

Due to their excellent properties, good processing and attractive appearance, brass and copper pipes are used in a wide range of industries (construction, roofing and gutter systems, architectural elements, for interiors, gas distribution in medical facilities and others). We only keep lengths of 3000 and 5000 mm in stock. In terms of hardness, we offer a predominantly ½ hard state. Soft or hard only to order from the factory. For copper pipes, we offer Cu-ETP and Cu-DHP alloys. For brass, mainly CuZn37. We supply materials outside the stock range from production or from our external suppliers.

Application:

  • CUPORI 210 (Frigo) -> special tube for air conditioning and refrigeration acc. EN 12735-1
  • CUPORI 430 LWC -> industrial copper tube in Level Would Coil acc. EN 12735-2

Standard:

  • meets EN 12735-1, 12735-2 and ASTM B280 standard requirements

Inner clean:

  • sealed after the cleaning process
  • bright, clean and dry internal surface

Working pressure*:

Maximum allowable internal working pressure of the tube is calculated and based on a calculation method according to German standards with safety factor 3.5 and working temperature of +20 °C. In calculation tensile strenght (Rm) is 200 N/mm2, which corresponds the temper of soft annealed tube. Calculated values are valid only for tubes not fittings.
