Copper pipes are produced in Serbia of 100% Serbian copper. Therefore,  we can supply copper tubes with  ~ Eur 1~  form. This means that the tubes are not subject to additional 4.8% European duty..

::  LPG (Auto gas) copper pipes

 

 

 

Further to the recent enforcement of the new EEC/UNO

R67- 01 norms, COPTECH  doo has developed and

approved high pressure copper pipes for LPG (auto gas)

vehicles able to successfully get through the very stringent tests it contemplates.

 

 

Copper pipes:                                with and without PVC cover

Outside diameters :                        6 and 8 mm

Wall thickness :                             0.8,  0.9  and 1.0 mm

Guaranteed copper content :           99,90% min.

System type :                                automotive

Available in rolls :                           66 m, 50 m, 25 m.

Minimal quantities per order :          10.000 meters.

 

 

 

Pipes have "LPG 67R01" mark on it  PVC cover.

* Values indicated in the table relate to outer diameter (excluding PVC coat). PVC coat thickness ranges from 1.4 to 2.0 mm.

** Copper  tube weight only (excluding PVC coat).

*** Values indicated for pressure in the table above are computed for soft tubes, without PVC cover, with safety factor N=5. Values indicated for allowable pressure relate only to tubes, not to their joints. 

 

Copper tubes are produced according to Quality Management System ISO 9001:2000

 

Our copper tubes are produced in Serbia of high phosphorus copper, designation Cu-DHP (according to EN 1057), with guaranteed copper content of 99,90% min. and and phosphorus content 0.015 -0.040%.

 

PVC coating reduce heat loss, prevents burns in users, protects copper tubes from aggressive environments and prolongs its service life. Plastic insulation layer is elastic and enables bending and all other working operations during installation.

Material used to coat copper tubes is polyvinylchloride (PVC) of the following characteristics:

  • Density: 1400 - 1500 kg/m³
  • Elongation: 207 %
  • Breaking strength: 14 N/mm 2
  • Maximum working temperature: +95C
  • Minimum bending temperature: -10C
