Automotive liquefied petroleum gas or autogas is a term broadly used for liquefied petroleum gas (LPG), when used for land vehicle propulsion. The calorific value of LPG is similar to that of petrol, and thanks to this property, it constitutes an excellent automotive fuel. The main ingredients of autogas are propane gas (C3H8) and butane gas (C4H10). Subsequent to the recent adoption of European Regulation ECE-R67, Halcor developed TALOS LPG copper tubes for LPG vehicle use. These tubes are successfully subjected to especially stringent tests.

TALOS LPG copper tubes are manufactured according to the Harmonised European Specification ΕΝ 12449. Their plastic outer coating reduces heat losses, prevents burns to users, protects copper tubes against harsh environmental factors, and provides longer tube service life. The outer plastic coating is flexible and allows bending or other operations during installation.

TALOS LPG copper tubes meet the requirements of ECΕ-R67, and also comply with the German Code AD 2000/W6 for pressurized containers.

* The values noted in the table refer to the outer diameter of the copper tube, excluding the plastic coating.

Coating thickness varies between 0,7 and 1,0 mm.

** Copper tube weight only (excluding plastic coating)
The maximum permissible operating pressure values are calculated for R200 material condition. The safety factor is considered equal to 3.5. Due to manufacturing tolerances, the minimum coating thickness is considered.Any treatment following product delivery is not taken into consideration. For operating temperatures up to 100°C inclusive.
