System Gas

The SYSTEM GAS copper tube in Cu DHP 99.9% copper - EN 1057, insulated with sheath in closed cell, expanded polyethylene, is produced with cutting-edge machinery and explicitly made for building gas distribution plants in civil residential buildings and according to the provisions under the UNI CIG 7129 standard for chased in pipes.

Characteristics

The internal air chamber between the copper tube and the coating itself allows gas to exit the building if there are any leaks from the feeding plant.

Silmet SYSTEM GAS is the optimal solution for building chased in gas distribution systems.

The core of the SILMET SYSTEM GAS 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.


Supply

The Silmet SYSTEM GAS copper tube is supplied in 50-metre coils (25 metres with Ø 22 mm) marked at intervals also indicating the relative metres.

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