SILMET PVC GAS, a copper tube pre-insulated with PVC, produced with cutting-edge machinery, complies with all the international reference standards, is manufactured according to  D.P.R. 1095/68 and  D.M. n. 174 of 06.04.2004 of Italian Department of Health - ref. European Council Directive n. 98/83/EC as far as the transport of drinking water is concerned and is suitable for building plants for transporting gas (UNI CIG 7129:2001). It is coated with a yellow polyvinyl chloride (PVC) sheath that makes it easy to recognise during installation; it is non-toxic, odourless and free from chlorofluorocarbons (CFC).

The characteristics of our coating in PVC GAS make the tube resistant to abrasions and corrosion and the particular internal structure allows the correct expansion of the copper tube without jeopardising the condition of the coating.

The PVC coating is odourless, non-toxic and is made without the use of CFC. It is suitable to be used in plants with operating temperatures ranging from -80°C to +100°C.

The PVC GAS copper tube is supplied in 50-meter coils (25 meters with Ø 22 mm)  marked at intervals also indicating the relative meters.

The main characteristics of the PVC GAS sheath are excellent plasticity, mechanical resistance to abrasions and corrosion, all ensuring that the tube lasts for a long time. Perfect adherence to the tube without insulation: the coating complies with UNI 10823:2000 "Coated copper tubes for gas application in underground zones".
