copper tubes for LPG vehicles

 

Driving an LPG vehicle is safe, easy and, best of all, much cheaper than petrol or diesel.

 

Further to the recent enforcement of the new ECE/UNO R67- 01 norms, COPTECH  doo has developed high pressure copper pipes for LPG (auto gas) vehicles able to successfully get through the very stringent tests it contemplates.

 

::  Our offer: High pressure soft copper tubes for LPG vehicles

 

Our copper tubes for LPG (autogas) vehicles are produced according to UN EC R67-01 regulative.

                       

 

In our offer we have copper tubes with or without PVC cover with outside diameters Ø 6 and 8 mm with wall thickness 0.8, 0.9 and 1.0 mm.

 

Tubes have "LPG 67r01" mark printed on it PVC cover.

Copper tubes are produced in Serbia according to Quality Management System ISO 9001:2000 and with mechanical properties according to EN 1057:2006 standard. EN 1057 is the European reference standard at continental level for the manufacture of copper gas and water tubes in water and heating applications. Copper tubes have minimally 99.90% of copper.

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:

Auto gas is the term generally used for Liquefied Petroleum Gas (LPG), when it is used for the propulsion of road vehicles. LPG provides high quality energy for Civil, industrial, handicraft, agricultural and motor use.
The main component gases of Auto gas are propane (C3H8) and butane (C4H10).
Auto gas is colorless, odorless and heavier than air. A sulphur based chemical (ethyl mercaptan) is added to give it a smell, so that even a very small leak can be easily detected. LPG Auto gas burns readily in air and has an energy content similar to petrol, which makes it an excellent fuel for automotive use. Already 4 million cars worldwide are running on LPG/ Auto gas and this figure is fast increasing everyday.

 

The Safety Record

LPG (Autogas, Elpiji, GPL, TNG, UNP..) has an excellent safety record throughout the world, both in terms of its storage, transportation and use. Extensive safety tests have been undertaken with respect to its use and the conclusions reached are that it is substantially safer than petrol due to its more robust fuel tank being more resistant to impact damage. Also the electronic solenoid valves trip in case of an impact not allowing fuel to go beyond the circuit to the engine. All tanks are fitted with relief valves that provides an escape for the gas should the tank come in contact with extreme heat. Tanks are not filled with more than 80% of total capacity. This ensures there is sufficient room for the liquid to expand when heated or the temperature being high.
 

Morever, in any eventuality of a leakage the gas escapes in the air and not remain in the engine like petrol to catch fire.

In fact the use of Auto gas is safer than Petrol as cylinders/tanks are kept horizontally in a car and adapter allows the liquid to flow all the way to magnetic valves before converting to gas.
