SMISOL® Gas
Resistant and gas-proof.
Applications
- Distribution of liquid and gaseous fuels with particular reference to underground trenching.
Advantages of the product
Tested and guaranteed stabilised polyvinyl resin sheath. It allows for underground trenching tube installation, as indicated by UNI 10823.
Electrical Insulation resistance that, as per UNI 10823, must be equal to or greater than 100 MΩm2, it also meets the requirements for UNI 7129.
Extremely low eccentricity values, a very important feature for jointing operations.
CE marking
Main features
This copper tube is manufactured according to standard EN 1057, during production it is sheathed in a PVC full cross-section protective covering (without air channels) according to UNI 10823.
The properties of SMISOL® Gas in terms of melting point, resistance to fire and pressure, gas impermeability and the absolute sealing performance of brazed and soldered joints, become indispensable in the case of domestic distribution of gas fuel, where the utmost safety guarantees are mandatory and enforced by technical standards and by legal provisions.
Furthermore, in accordance with EU Regulation 305/2011 for construction products (CPR), SMISOL®Gas copper tubes are CE marked. A further guarantee of compliance with prevailing regulation standards is assured with the achievement of UNI-IGQ Quality certification.
Internal protection
During production, the tubes are subjected to a patented passivation treatment and stabilisation of the inner wall. SMISOL® Gas copper tube has a carbon residue C<0,06 mg/dm2, much lower than that required by EN 1057 which defines a carbon content limit of C≤0,20 mg/dm2.
External protection
Tested and guaranteed stabilised polyvinyl resin sheath. The sheath protects against damage from external agents such as building materials (eg. quick-setting cement) and damage caused by impact during the construction site transportation. It allows for underground trenching tube installation, as indicated by UNI 10823: “the coating is obtained by extrusion, in a seamless and continuous manner, externally and internally smooth, with a uniform nominal thickness, with full adhesion to the copper tube external wall along its entire surface to ensure absence of air pockets and prevention from slipping off”.
It is tested in line in order to ensure the required electrical Insulation resistance that, as per UNI 10823, must be equal to or greater than 100 MΩm2.
Scope of supply
Seamless, drawn copper tube, produced in accordance with EN 1057, R220 annealed physical status, phosphorised Cu DHP (Cu + Ag : 99.90% min. – P: 0.015÷0.040%) according to EN 1412, treatment of pre-passivation on the internal surface of the tube with a carbon residue of less than 0.06 mg/dm2, indelible labelling every 60 cm with punching of the external surface of the copper tube, produced in compliance with the measures set out in UNI 7129, covered at the production stage with a PVC insulation with star shaped section, yellow RAL 1003 colour, covering thickness of 1.5mm complying with UNI 10823 standard with insulation electric resistance equal to or greater than 100 MWm2, specific for the transportation of gas for domestic use in underground areas as foreseen by UNI 7129, ink labelling on the external surface of the insulation with progressive indication of the measurement in metres with SMISOL® Gas label.
