General characteristics PVC-U Developed in 1930 in Germany, PVC-U (rigid polyvinyl chloride - unplasticized) is obtained through the polymerization of a vinyl chloride monomer. The presence of chlorine in the PVC-U molecule results in a high performance resin, in terms of thermal stability and chemical and mechanical resistance, up to temperatures of 60° C. The different formulations obtained by adding suitable additives and stabilizers render the PVC-U the most versatile of all plastic materials, allowing it to be adapted to many applications involving fluids under pressure. PVC-U...

Per maggiori dettagli consultare la tabella “Caratteristiche e dimensioni dei pennelli - applicatori”. Si consiglia comunque, di usare un applicatore/pennello con dimensioni non inferiori alla metà del diametro del tubo. L’applicazione del collante sul tubo e raccordo, deve essere estesa per l’intera lunghezza delle superfici di accoppiamento: - per l’intera lunghezza di incollaggio del tubo, segnata in precedenza sulla sua superficie esterna (fig. 6) - per l’intera profondità del bicchiere del raccordo fino alla battuta interna (fig.7) 6) Inserire immediatamente il tubo nel raccordo per...

Warnings l In the case where the external diameter of the pipe and the internal diameter of the fitting are at opposite extremes of their tolerance values, the dry pipe cannot be inserted in the dry socket of the fitting. Insertion will only be possible after having applied the Cleaner and Solvent Cement to both parts to be joined. l The solvent cement is manufactured from the same PVC resin used for the production of the pipes, fittings and valves. Unless otherwise specified, the solvent cement used on the surfaces to join must also be usable with the following tolerances: - maximum...
