product range

In our offer we have a wide range of copper tubes for various industrial applications.

  

Delivery Form:

            Level Wound Coils (LWC)

            Straight Lengths (half-hard  and hard)

            Coils

            Capillary tubes

 

The copper tubes are produced in Serbia of high phosphorus copper, designation Cu-DHD (according to EN 1057), with guaranteed copper content of 99.90% min. and phosphorus content 0.015 - 0.040%. We have copper tubes made of some other copper alloys.

Product range:

In our offer we have copper tubes with inner diameter Ø 5 - 76 mm and wall thickness 0.35-2.5 mm, in soft, half-hard and hard conditions with Imperial and Metric dimensions..

 

Copper tubes are widely applied:

                       

                         OD (Outside diameter)

 

                         Bore

 

                         Thickness or gauge (swg)

 

 

Conversion of bore to wall thickness = (OD – bore) / 2

Weight and  working pressure

 Weight and maximum allowable working pressure of fluids are computed using the following equations for each copper tube size:

For weight:

For pressure:

Q = (D - S) x S x π x γ, gr/m

P = 200 Rm S / DN, bara

where: where:
D - outer diameter, mm 200 - conversion constant
S - wall thickness, mm Rm - tensile strength, N/mm²
γ - specific weight of copper, 8.94 kg/dm³ S - wall thickness, mm
π - 3,14 D - outer diameter, mm
  N - safety factor (5)

In our offer we have sanitary and industrial copper tubes mostly of the following standards:                          EN 1057, EN 12735-1, EN 12449, ASTM B280, ASTM B68/251, ASTM B88, GOST 617, GOST 11383, JUS C.D5-500, JUS C.D5-502 ...
