PVC

SILMET PVC, 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

The characteristics of our PVC coating make the copper tube resistant to abrasions and corrosion and the particular internal star-shaped 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 copper tube is supplied in 50-metre coils (25 metres with Ø 22 mm) marked at intervals also indicating the relative metres.

The core of the SILMET PVC is the ESENCOR copper tube providing excellent protection against corrosion and is the result of scientific studies and tests that guarantee a considerably lower level of residual carbon than that required by manufacturing standards.

The main characteristics of the SILMET PVC sheath are excellent plasticity, mechanical resistance to abrasions and corrosion, all ensuring that the tube lasts for a long time.

The pre-insulated copper PVC SILMET tube is mainly used in under-floor heating plants, water distribution systems and in the production of gas and air lines.


Supply

The copper tube EN 1057 is marked СЄ as required by EU 305/2011 EU Construction Products Regulation (CPR).
