SILMET PVC GAS, a copper tube pre-insulated with PVC used for gas distribution. It is produced with cutting-edge machinery, in compliance with all the international reference standards and manufactured according to Presidential Decree no. 1095/68 and Ministerial Decree no. 174 of 6 April 2004 of the Italian Department of Health - ref. European Council Directive no. 98/83/EC regarding the transport of drinking water and suitable for building gas distribution plants (UNI CIG 7129).
Characteristics
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 (CFCs).
The characteristics of our coating in PVC GAS make the copper tube resistant to abrasions and corrosion and the particular internal structure allows its correct expansion without jeopardising the condition of the coating.
The PVC coating is odourless, non-toxic and is made without the use of CFCs. 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-metre coils (25 metres with Ø 22 mm) marked at intervals also indicating the relative metres.
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 "Coated copper tubes for gas application in underground zones".
Supply
The copper tube EN 1057 is marked СЄ as required by EU 305/2011 EU Construction Products Regulation (CPR).
