Filtri spirale a luce continua in acciaio al carbonio grezzo, zincato caldo, acciaio inox aisi 304/316

Le crescenti problematiche che intervengono nella infissione di pozzi per acqua – legate in particolare alle varie tipologie di terreni da filtrare – ci hanno portato a studiare e realizzare una gamma completa di filtri in acciaio al carbonio e acciaio inox fabbricati col sistema della saldatura continua in elicoidale, indispensabile per ottenere determinati fattori di pregio quali:

  • Massima rotondità.
  • Uniformità di spessore.
  • Diametri di qualsiasi misura intermedia.
  • Nessun limite di lunghezza degli elementi prodotti.
  • Alta resistenza meccanica allo schiacciamento.

Diametri standard prodotti: dal 114 mm al 1060 mm. Spessori disponibili: 3 – 4 – 5 – 6 – 7 – 8 mm.

I materiali impiegati sono di prima qualità; accuratissima la scelta delle lamiere coils, decappate e cesoiate a regola d’arte, senza sbavature. Finita la lavorazione, i tubi vengono
controllati ad uno ad uno. Inoltre ogni tubo può essere opportunamente smussato per facilitare
la saldatura testa con testa. I sistemi di giunzione possibili sono illustrati in figura.

A richiesta possiamo fornire altri filtri di dimensioni, generatrici e filo diverse.
